All About Vision

Children's Vision & Learning

According to experts, 80% of learning is visual, which means that if your child is having difficulty seeing clearly, it can adversely affect their school performance.

20/20 Vision Is Not Enough

If your child has been told they have ‘20/20 sight’, it means you can clearly see the letters on the vision chart at 20 feet away. However having 20/20 eyesight is not enough.

With 20/20 vision, your child may pass the vision screening and excel in seeing all the letters on reading the vision charts on the wall, but still lack the necessary visual skills needed for reading, writing, and learning, all of which can adversely impact your one's scholastic achievements.

Visual Skills and Learning

As mentioned above, poor visual skills, rather than poor eyesight, is often at the root of learning problems. Many children struggle with schoolwork because of one or more of the following critical vision skill deficiencies:

EYE MOVEMENT CONTROL Poor eye movement control often results in errors, such as reversing letters, losing one’s place, and inserting or skipping letters, numbers, or words.

FOCUSING This allows the eyes to quickly refocus from near to far objects and vice versa — essential for reading the board and writing notes.

EYE ALIGNMENT Your eyes need to point accurately and simultaneoulsy, to the object viewed. If one of the eyes deviates it can result in double vision, and affect reading skills and classroom learning.

CONVERGENCE To look at a near object, the eyes must converge toward each other. If convergence is not maintained, one eye turns in or out, causing the object or word to appear double, blurry, or mislocated.

VISUAL PERCEPTION Those with poor visual perception typically confuse numbers and letters, such as “b” with “d”, “p” and “q”, or “6” and “9”, have difficulty recognizing words, frequently lose their place in a text, and are unable to distinguish right from left, among other things.

How Undeveloped Visual Skills Affect Kids Learning

All too often, it is an undiagnosed vision problem that’s at the root of the struggle to focus at a distance (such as the board), maintain concentration, or skip lines when reading. This makes bright children seem like they can’t grasp the subject at hand, which, in turn, can result in secondary behavioral issues, such as frustration and boredom — an overlooked component of a child’s diagnosis with ADD/ADHD or a learning disability.

If your child is struggling at school, contact us today for an in-depth vision exam to assess their essential visual skills.

Learning-Related Vision Problems

Signs and Symptoms

Some of the most common roadmap symptoms of learning-related vision disorders are:

Double vision, particularly during or after reading
Poor handwriting
Hyperactivity or recklessness during class
Word and letter reversals
Easily distracted during reading
Poor reading comprehension
Poor overall school performance
Circumventing of reading
Blurred vision, especially after reading or working closely
Eye Strain or frequent headaches

Call us to schedule a comprehensive child’s vision exam if your child exhibits one or more of these signs or symptoms and is exhibiting these types of problems in school.

Comprehensive Child Vision Exam

A comprehensive child's vision exam includes tests performed in a routine eye exam, plus specific additional tests for detecting learning-related vision problems.

Extra tests would include accommodation, binocular vision, and ocular motility testing. In addition to these—and depending on the type of problems your child displays— we may recommend additional testing, either with one of our optometrists or with a vision development specialist.

Vision Therapy

Special reading glasses or vision therapy may help your child if s/he has a learning-related vision problem that cannot be corrected using regular glasses or contact lenses. Vision therapy entails eye exercises and other activities specifically tailored for each patient to strengthen vision skills.

Are Contact Lenses a Good Choice for Kids?

Many children who wear glasses want to switch to contact lenses, especially older children who are concerned with their appearance. So, how do you know if and when contact lenses might be an option for your child?

Contact lenses may not only improve a child’s confidence in their appearance but they can also be very convenient for active children who play sports or those who tend to lose or break their glasses.

Yet before you jump to schedule an appointment with the optometrist, it’s important to know that while contact lenses are a great solution for many, they are still medical devices that require care and responsibility. Carelessness with contact lenses can lead to infections, irritation, scratched corneas, pain, and sometimes even vision loss. So if you want to know if contact lenses are a good choice for your child, read below and think about whether your child is mature and responsible enough to take proper care of his or her eyes.

At What Age Can a Child Start Wearing Contact Lenses?

The recommended age for kids to start considering contact lenses varies however it is generally accepted that sometime between 11 and 14 is ideal. Some doctors will recommend them even for children as young as 8 years old who have shown that they are responsible enough to use them. Contact lens use requires good hygiene and cleanliness so if your child shows those traits, she may be ready. Additionally, if he is highly motivated to wear contacts and if he has the support of his parents, this will help in ensuring that the daily regimen is a success.

What is the Process of Getting Fitted for Contacts?

The first step is to schedule an appointment for a contact lens exam with your optometrist. The eye doctor will perform a vision exam and go over the different options for contact lenses, depending on the prescription, the health of the eye and lifestyle and personal preferences. Contact lenses are designed with a number of options including the lens materials used (soft or rigid gas permeable), the replacement schedule (if disposable, how often you replace the pair – daily, weekly, biweekly or monthly) and the wear schedule (daily or extended overnight wear). Often doctors will recommend daily lenses for children because they are thrown away after each use so there is less care involved, less buildup and less risk for infection.

Then the doctor will give a training on inserting and removing the lenses as well as instructions for proper care. Your child will probably be given a schedule for wearing the lenses for the first week or so in order to allow their eyes to adapt. During this time you may have to be in touch with your eye doctor to assess the comfort and fit of the lenses and you may have to try out a couple of options in order to find the best fit.

Purchasing Contact Lenses

As a medical device, contact lenses require a prescription and should only be purchased from a licensed distributor such as an eye doctor. Unauthorized or unmonitored contact lenses can cause severe damage to your eyes that could result in blindness. This is true also for cosmetic lenses such as colored lenses or costume lenses. Any time you are putting a lens in your eye, you must have a proper prescription.

Following are some basic contact lens safety tips. If your child is responsible enough to follow these guidelines, he or she may be ready for contact lens use:

Always follow the wearing schedule prescribed by your doctor.
Always wash your hands with soap before applying or removing contact lenses.
Never use any substance other than contact lens rinse or solution to clean contacts (even tap water is a no-no).
Never reuse contact lens solution
Follow the eye doctor’s advice about Don’t swimming or showering in your lenses
Always remove your lenses if they are bothering you or causing irritation.
Never sleep in your lenses unless they are extended wear.
Never use any contact lenses that were not acquired with a prescription at an authorized source. Never purchase cosmetic lenses without a prescription!

Contact lens use is also an ongoing process. As a child grows, the lens fit may change as well, so it is important to have annual contact lens assessments. Plus, new technology is always being developed to improve comfort and quality of contact lenses.

Contact lenses are a wonderful invention but they must be used with proper care. Before you let your child take the plunge into contact lens use, make sure you review the dangers and safety guidelines.

Low Vision Aids for Computer Users

Low vision is a condition, often caused by a number of eye diseases that damage parts of the eye, in which individuals have significantly reduced vision.

SCHEDULE AN APPOINTMENT

Computer Use and Low Vision

Individuals with low vision have some sight, but usually, it is not sufficient to get by in daily life without some assistance. Often they are not able to read, drive, cook, or work on a computer without a visual aid. Today there are many low vision aids available on the market to help those with low vision to function independently in performing daily tasks.

Computer use is one activity that often requires assistance and the good news is the technology to aid computer users with low vision is always improving.

Here are some devices and programs on the market to help:

Text Magnifying

There are a number of ways to enlarge the text on your computer screen in addition to handheld magnifiers.

Via Your Computer Operating System: Both newer generation Windows and Mac operating systems have screen magnifiers built-in. These do not have as many capabilities as purchased screen reader programs but for many with mild low vision, they may be sufficient.

Via Browser: When using the Internet most browsers (Chrome, Safari, Firefox, and Internet Explorer) allow you to change the size of the page or text on the screen to suit your needs. To enlarge the text on a PC simply hold down the Control (“Ctrl”) key on your keyboard and either tap the “+” key or roll the wheel on your mouse. To reduce the size tap the “-” key or turn the mouse wheel in the opposite direction. On a MAC, you press command and shift at the same time along with the “+” or “-” keys.

Additionally, the browser might have a drop-down option under the “view” tab that allows you to Zoom the screen in or out or make the text larger or smaller. Keep in mind that if you are using a larger higher quality screen, this will enable you to see bigger and more clearly as well.

Screen magnification programs: there are a number of free and paid software programs that will enlarge the text, picture and images on your computer screen.

Screen Readers and Text to Speech Programs

There are a number of programs that enable you to “read” what is on the computer without needing to see it - these are designed for people that are totally blind as well. These programs work by scanning the text and icons on a page and converting it to speech which is read aloud. Some of these programs also have a cursor on the page that moves along with the voice.

Up to date Microsoft and Apple operating systems do have simple, built-in screen readers but they may be limited. The Chrome browser and Android devices do as well. Nevertheless, depending on your abilities, you may prefer to purchase a program with more comprehensive options and usability.

If you are looking for something simpler, text-to-speech programs exist in which you select a portion of the text you want to read and the program reads it for you.

Screen Contrast

Adjusting your screen to the highest contrast will enable the letters and images on the monitor to stand out. Font should be adjusted to achieve a dark text on a light background. Further it is advisable to reduce glare as much as possible. This may require adjusting window shades and indoor lights or even purchasing an anti-glare screen to reduce glare that can’t be eliminated.

Hardware

You can purchase special keyboards, mice and monitor magnifiers made specifically to enhance usability for those with low vision. Purchasing a large LCD screen for your monitor will also help to enhance visibility.
Computers can be a window to open our world to information, connections, work and play. Individuals with low vision can access all of this as well with the assistance of specialized software, devices and programs using the strengths and senses that they do possess.

Ask your eye doctor for more information about how we can help.

Why are Eye Exams Important?

For both adults and children alike, eye exams are an important part of one’s general health maintenance and assessment. Your eyes should be checked regularly to ensure that you are able to see as best as possible. Regular eye health exams will also check for signs of eye disease or conditions that can affect not only your vision but your overall health. Vision and eye health is such a critical part in learning and development, therefore, we highly recommend eye exams for infants and children.

Vision Screening vs. an Eye Exam

When we recommend regular eye exams, this should not be confused with a vision screening. A vision screening is a basic test that indicates if you have difficulty seeing and require further assessment and corrective measures. It can be performed by anyone, whether it is a school nurse, a pediatrician or even a volunteer at a vision clinic. A vision screening usually only checks vision, it does not check eye health. Also, most vision screenings for kids only check for nearsightedness (when you can not see far), but what happens when the majority of children are farsighted? Most of the time many of these kids get overlooked.

A comprehensive eye exam on the other hand, can only be performed by an eye doctor as it requires special knowledge and equipment to look around and into your eye to check your eye and vision health. Such an exam can assess whether there are underlying causes for vision problems and whether there are any signs of disease which can threaten your site and the health of your eye. A comprehensive eye examination can also diagnose symptoms of diabetes, high blood pressure, high cholesterol, tumors, cancer, autoimmune disorders, and thyroid disorders. A comprehensive eye examination will also provide an accurate prescription for eyeglasses or contact lenses.

Eye Exams for Eye Health

Eye exams are critical because many vision threatening eye diseases such as glaucoma, macular degeneration, cataracts, or diabetic retinopathy have no or minimal symptoms until the disease has progressed. In these cases, early detection and treatment is essential to halting or slowing down the progression of the disease and saving eyesight. During a comprehensive eye examination, your eye doctor will be looking for initial signs of these diseases. If a problem with your eyes arises such as red eyes, eye allergies, dry eyes, eye swelling,eye pain, always seek an eye doctor as your first doctor to call since they are specifically trained to treat eye diseases.

Eye Exams and Children

If your child is having developmental delays or trouble in school there could be an underlying vision problem. Proper learning, motor development, reading, and many other skills are dependent upon not only good vision, but your eyes functioning together. Children that have problems with focusing or hand-eye coordination will often experience frustration and may exhibit behavioral problems as well. Often they don’t know that the vision they are experiencing is abnormal so they aren’t able to express that they need help. Many conditions are much easier to treat when they are caught early while the eyes are still developing, so it is important to diagnose any eye health and vision issues as early as possible.

Eye Exams Over 40

Just like the rest of our bodies, our eyes begin to weaken as we age. There are a number of common age-related eye conditions such as presbyopia, cataracts, and age-related macular degeneration that can begin to affect your vision and your daily life. While some of these conditions are more of an inconvenience, others could lead to vision loss and dependency.

In addition to regular yearly eye exams, it is important to be aware of any changes in your eye health and vision. Also know your potential risk factors as well as your family ocular and medical history. Over half of the vision loss worldwide is preventable with proper treatment and care.

Preparing for an Eye Exam

For both adults and children, an eye exam is a critical part in maintaining your overall health and well-being, and therefore, regular eye exams should be incorporated into your health routine. Comprehensive eye exams assess your vision and the health of your eye, looking for early signs of disease that may not have obvious symptoms. You should not wait until you experience a vision problem or symptoms of an eye condition to schedule a routine exam.

Depending on your age, family history, general health and eye health, it is recommended to have an eye exam every one to two years. Of course if you experience any serious symptoms that affect your eyes or your vision, you should contact your eye doctor immediately.

The Difference Between an Optometrist (OD) and an Ophthalmologist (MD or DO)

Confusion about the difference between optometrists and ophthalmologists is common, and many people are not aware of how the two eye care professionals differ.

Optometrists

Optometrists or Doctors of Optometry attend optometry school which is usually at least four years of graduate level training. They are able to perform eye exams, provide prescriptions for eyeglasses and contact lenses, and diagnose and treat eye diseases as as glaucoma, dry eyes, or eye infections that may require medication or drops. They can consult with and co-manage patients in pre- or post-op surgical care, however they do not perform surgery.

Ophthalmologists

Ophthalmologists are medical doctors that attend medical school and later specialize in ophthalmology. They are able to do all of the services mentioned above but also perform eye surgeries such as cataract surgery, refractive surgery such as LASIK and deal with more urgent eye conditions such as retinal detachment.

Infant and Child Eye Exams

According to the American Optometric Association (AOA) children should have their eyes examined by an eye doctor at 6 months, 3 years, at the start of school and then at least every 2 years following. If there are any signs that there may be a vision problem or if the child has certain risk factors (such as developmental delays, premature birth, crossed eyes, family history or previous injuries) more frequent exams are recommended. A child that wears eyeglasses or contact lenses should have his or her eyes examined yearly.

Adult Eye Exams

Healthy adults under 40 with good vision and who do not wear eyeglasses or contact lenses are recommended to have an eye exam at least every two years. Those that do use vision correction or have a health issue such as diabetes, high blood pressure or another health condition that can have an impact on your eye health should schedule a yearly exam, unless the eye doctor recommends more frequent visits.

Once you reach 40, you become susceptible to a number of age-related eye conditions such as presbyopia, cataracts or macular degeneration, therefore annual or bi-annual exams are strongly recommended.

As you continue to age, particularly after age 55, the risks of eye disease increase, and early detection can be critical to preventing significant vision loss or blindness. Scheduling a yearly eye exam can make all the difference in maintaining your independence and quality of life.

How to Prepare for Your Exam

Prior to your exam you should decide whether you will be seeking special services such as a contact lens exam or LASIK consultation. These services may cost extra. Check with the doctor’s office or your insurance provider to see if they cover any of the exam expenses.

You need to know if you have medical insurance, vision plan coverage or both. Medical insurance usually does not cover “wellness/refractive” exams for glasses or contact lenses. Vision plans will cover exams for glasses or contacts, but usually cannot be used for red eyes, floaters, or other medical eye health problems. Please bring your insurance cards with you.

In addition to bringing your current pair of glasses or contacts if applicable, it is important to be aware of your personal and family history and to have a list of medications or supplements you are currently taking. Your pupils will probably be dilated as apart of your exam, so plan accordingly.

Your Comprehensive Eye Exam

Your eyes are one of the most complex organs in your body. A comprehensive eye exam to assess your visual system and eye health involves a number of different of tests. Unlike a simple vision screening, which only assesses your vision, a comprehensive eye exam includes a battery of tests in order to do a complete evaluation of the health of your eyes and your vision.

The tests that you will undergo in a comprehensive eye examination may vary from eye doctor to eye doctor but here are are some common exams that you may encounter:

Patient Background and History

One of the most important parts in a comprehensive eye exam is your patient health history. This information will alert your doctor to any conditions that should be monitored closely, such as an allergy to any medications, current or family history of systemic or eye pathology or environmental conditions that could be affecting your vision or eye health. This will also help your doctor to determine any preventative eye care measures that are relevant to keep your eyes healthy for years to come.

Visual Acuity

Visual acuity is a measurement of your vision using an eye chart, the Snellen Eye Chart. In this test the patient is seated at a standard distance and is asked to read letters or symbols of various sizes, which get smaller as you move down the chart. The results are the familiar ratio of 20/20, 20/40 etc. which is a comparison of your vision compared to the average person with good vision, which is typically 20/20. For example, a patient that has 20/40 vision, can only see at 20 feet what the normal person can see from a distance of 40 feet. This test is a preliminary test of how clearly you are seeing in each eye but it does not give you a prescription for corrective lenses.

Refraction

Those who don’t have 20/20 vision have what is referred to in most cases as a “Refractive Error.” The patient may have nearsightedness, farsightedness, astigmatism or other eye conditions that prevent the patient from seeing 20/20. A refraction will tell the doctor which prescription lenses will correct your eyesight to achieve 20/20 vision or whichever amount your vision is correctable to.

A refraction may include a couple of steps.

Retinoscopy

Retinoscopy is a test that allows the doctor to obtain an approximate prescription for eyeglasses. In this test the doctor uses a hand-held instrument called a retinoscope that shines a light into the patient’s eye. The doctor then analyzes the reflex of the light from the patient’s eye to determine the patient’s prescription for glasses.

An instrument called a phoropter is something most patients associate with an eye exam. This space age appearing instrument, positioned in front of the patient’s face during the eye exam, gives the doctor the ability to determine the patient’s focusing ability as well as their eye alignment. The phoropter also determines which, out of the hundreds and hundreds of potential eyeglass prescriptions, will help the patient see as clear as possible. Using the phoropter, the doctor will ask the patient which series of lenses makes their vision the clearest.

While retinoscopy is quite effective for children and nonverbal patients, there are now a number of computerized or automated instruments available today to help doctors accurately determine a patient’s eyeglass prescription.

Autorefractors and Aberrometers

Autorefractors and aberrometers are computerized machines that are able to measure your refractive error to determine your prescription for glasses or contact lenses. These instruments are usually used in addition to testing described earlier:

– An autorefractor is similar to retinoscopy, which electronically analyses the light reflex from the patient’s eye.

– An aberrometer measures distortions or aberrations in the cornea and lens of the eye that disrupt proper focus of light on the retina. Using wavefront technology, the instrument measures the rays of light as they pass through your eye to look for imperfections which may indicate a refractive error.

Eye Focusing and Eye Teaming Tests

During the comprehensive eye exam, your eye doctor will also want to test how your eyes function individually and together from a mechanical perspective. In order to see clearly and comfortably, your eyes need to work together as a team.

Eye Health

The final and most important aspect of a comprehensive eye exam is a check of your overall eye health. These tests (below) are done to identify any eye conditions or diseases, both inside the eye as well as the external parts of the eye, that could affect your vision and general health.

Slit Lamp Test

The slit lamp or biomicroscope is an instrument that allows the doctor to examine the internal and external parts of the eye in detail, such as the conjunctiva, iris, lens, cornea, retina and the optic nerve. The patient rests their forehead and chin on a headrest to stabilize the head, while the doctor looks into the eye with the slit lamp microscope, which is magnified with a high-intensity light. A slit lamp test enables the doctor to evaluate the eyes for signs of normal aging and eye pathology, such as conjunctivitis, cataracts, macular degeneration or retinal detachment. Early diagnosis and treatment of eye diseases are essential for preventing vision loss.

Tonometry

Tonometry is a test to detect glaucoma by measuring the pressure inside your eye or IOP (intraocular pressure). Glaucoma can cause vision loss and even blindness if the IOP in the eye is too high and damages the optic nerve.

The applanation tonometer, typically attached to a slit lamp, is one of the most common instruments used to measure the pressure in the eye. Prior to doing this test the doctor will numb the patient’s eyes using an anesthetic, before gently applanating (putting pressure on) the patient’s cornea to measure the pressure in the eye.

Pupil Dilation

During your comprehensive eye exam, your doctor may decide to do a dilated eye exam. In this test, your doctor will instill dilating drops in each eye, which would enlarge your pupils to give the doctor a better view of certain parts of the back of the eye. Dilation is done at the discretion of the doctor, with some patients dilated every year and others at specified intervals; the frequency of dilation will vary for each patient.

Typically the drops take around 20 to 30 minutes to take effect and may last up to several hours following the exam; each patient is different. Since more light enters your eyes when your pupils are dilated, you will be more sensitive to bright light, especially sunlight. Although your doctor may provide disposable sunglasses, you may want to bring a pair of sunglasses to wear after the exam to make it more comfortable until the drops wear off.

A comprehensive eye exam is an important part of your overall general health maintenance and should be scheduled on a regular basis. The findings from your comprehensive eye exam can give your doctor important information about your overall health, particularly diabetes and high blood pressure.

Children’s Vision – FAQ’s

Most parents believe that if their child had an eye or vision problem they would know. However, this is far from the truth for a number of reasons. First of all, children often can’t express or don’t realize the difficulty they are having, and often vision problems will be overlooked by the associated behavioral issues that come as a result of frustration. Further, many eye or vision problems don’t show symptoms until they have progressed significantly which often makes the condition harder to treat.

Conditions such as amblyopia (lazy eye) or strabismus (crossed-eyes) can be corrected more effectively when they are diagnosed and treated early at a young age. Further, the sooner you diagnose and correct a vision problem, the sooner your child will be able to achieve his or her potential without struggling with these difficulties. This is why it is critical to have your child’s eyes examined by an eye doctor at regular intervals. Here are some FAQ’s and answers about Children’s Vision that every parent should know:

Q: At what ages should children have their eyes examined?

A: The official recommendations for the American and Canadian Optometric Associations are that infants should have their first eye exams at 6 months. Following that, children with no known vision issues should have another exam at 3 years and then prior to entering kindergarten. Children who do not require vision correction or therapy should have a vision checkup every year or two years and those who use vision correction should have an annual eye exam. Of course if your child is experiencing difficulty in school or after school activities that may be due to a vision problem schedule an eye exam immediately.

Q: My child passed a vision screening by the nurse at school. Does he still need an eye exam?

A: Yes. Many schools implement a basic vision screening test to assess whether the child sees clearly at a distance, however these tests are limited in scope. They do not assess functional vision such as the child’s ability to focus, track words on a page or the eyes’ ability to work in tandem. They also do not look at the health of the eye itself. These tests are essential to know the comprehensive picture of how healthy the eyes are and how well they are doing their job. In fact, studies shown that up to 43% of children with vision problems can pass a vision screening test! A comprehensive eye exam will assess all of these functions as well as color vision, depth perception, and eye coordination.

Q: My child was diagnosed with strabismus and amblyopia. Can this be treated and if so, what are the options?

A: Especially when diagnosed early, chances of a complete correction for strabismus and amblyopia are good when treated properly. The optimal age for this to occur is before 8-10 years old. Depending on the severity of the strabismus (crossed-eye), surgery may be required to straighten and properly align the crossed eyes. Amblyopia (lazy eye) can then be treated using eyeglasses, eye patching, or vision therapy to strengthen the weak eye and train the eyes to work together. A doctor that specializes in pediatric optometry can assess the condition and discuss treatment options on an individual basis.

Q: What is vision therapy?

A: Vision therapy is a doctor-supervised, individualized program of exercises to strengthen the functions of the eye. It is used to correct issues with eye alignment, focusing, coordination, tracking and more. Vision therapy often utilizes tools such as specialized lenses or prisms and involves exercises both during office visits and at home to reinforce the changes. The process usually takes about 6 months to see lasting improvement.

Q: My son’s nearsightedness keeps getting worse – he needs a new prescription every year. Is there a way to stop this?

A: There is research that shows that progressive myopia can be stopped or slowed during the childhood years. There are a number of therapies that are used for what is called “myopia control” including multifocal eyeglasses or contact lenses, orthokeratology (ortho-k) or atropine eye drops. Speak to a pediatric optometry specialist to learn more about the options and what might work best for your child.

Q: Every morning it is a fight to get my child to wear her glasses. What can I do?

A: It may take time for your child to adapt to the feel of the glasses and to be comfortable seeing with them. For little children, you can find glasses that come with integrated headbands that can help to hold the glasses in place. It helps to be consistent in putting them on to allow the child to adapt to the feel of the glasses.

Very often, especially for small children that can’t tell you what is bothering them, the reason for a child’s refusal to wear glasses is that something is not comfortable. It could be that the prescription is not right, that the glasses pinch or that are feeling heavy. It could be worthwhile to take the glasses back to the eye doctor to ensure that they are in fact a proper fit.

Q: At what age is it acceptable for a child to wear contact lenses?

A: Contact lenses can be a great convenience, especially for kids that are active or tend to break or lose their glasses. However, they are a medical device that must be treated with proper care and hygiene. If a child is not responsible enough to take care of them properly he could end up with a serious eye infection, a scratched cornea or worse. Most experts agree that the youngest age that contact lenses should be considered would be between 10-12 depending on the child’s maturity and cleanliness. Consult with your eye doctor about what would be best for your child.

Your Infant’s Visual Development

Your baby’s visual system is not fully developed at birth and continues to develop gradually over the first days and months of life. In fact, from your baby’s perspective at birth, the world is black and white, blurry and rather flat. As the days and months go on, they begin to focus, move their eyes and start to see the world around them. While each child will grow and develop on his or her own schedule, knowing an infant’s vision milestones will help you ensure that your infant is on track to achieving good vision and eye health and start treatment early if there is a problem.

Birth – 3 months

Because newborn babies’ eyes and visual system are underdeveloped, they can not focus their eyes on close objects or perceive depth or color. Babies need to learn to move, focus and coordinate eye movements to team the eyes (have them move together as a team). The brain also needs to learn how to process the visual information from the eyes to understand and interact with the world. In fact, until about 3 months, the optimal distance a baby can focus on is about 8 – 10 inches from their face, about the distance their parents face will be during feeding.

Your baby will start to be able to perceive color within the first 2-3 weeks, however it will take a few months to learn how to focus and use the eyes, to track objects, differentiate between two objects and shift from one object to the other. During this time you may notice that the eyes appear crossed and do not work together or team. This is quite common at the early stages of development, however if one eye appears to be constantly turned in or out, seek a doctor’s evaluation.

At around three months, as hand-eye coordination begins to develop, a baby should be able to follow a moving target with their eyes and reach for objects.

4-6 Months

By 6 months, your baby will begin to move his eyes with more speed and accuracy, seeing at farther distances and focusing well. Color vision should be fully developed and the eyes should be able to work as a team and follow moving objects with relative ease. Hand-eye coordination and depth perception should be greatly improved as your baby will begin to understand the 3-dimensional world around them.

At six months, you should take your baby for his or her first comprehensive eye exam to ensure that the eyes are developing on track and there are no signs of congenital or infant eye disease.

7-12 Months

At this stage of development babies will be coordinating vision and body movements by crawling, grasping, standing and exploring the surrounding world. They should be able judge distances accurately, throw a ball toward a target and pick up a small object with their fingers. Delays in motor development can sometimes indicate a vision problem.

The First Eye Exam

While at 6 months, your baby will not be able to read an eye chart, eye doctors can perform an infant eye exam through non-verbal testing to assess visual acuity (for nearsightedness, farsightedness or astigmatism), eye teaming abilities and eye alignment. The eye doctor will also be able to see inside the eye for any signs of disease or problems that could affect eye or vision health.

InfantSEE®

InfantSEE® is a public health program in which participating optometrists provide a free comprehensive infant eye exam to babies between 6 and 12 months of age. The program was initiated to provide accessible eye and vision care for infants to ensure they have the best chances for normal development and quality of life.

If your child has any unusual symptoms such as excessive tearing, constant eye misalignment, red or crusty eyes or extreme light sensitivity consult an eye doctor as soon as possible.
