Too Young for Bifocals or Multifocals?

Need bifocal or multifocal glasses and you’re only in your 40’s? You’re not alone! Nearly 3 million Americans experience age-related vision changes in their 40s due to presbyopia —age-related farsightedness.

Our eyes naturally start to change as we get older. Presbyopia results from the lens inside the eye becoming more rigid. This affects your ability to focus on objects up close.

People with presbyopia will notice that reading a newspaper or a menu becomes increasingly more challenging. Tasks such as painting and sewing may cause you to squint or hold the object at arm’s length. If this sounds familiar to you, chances are you have presbyopia.

Having to switch glasses for near, medium and far vision gets tiresome pretty fast. The beauty of bifocal and multifocal lenses is that they offer two or more prescriptions in a single eyeglass lens.

Below we explain more about bifocal and multifocal lens options.

Bifocal Glasses

Bifocal literally means “two focuses.” Bifocal lenses contain two different prescriptions: the upper section allows you to see into the distance while the lower section is for near vision.

Bifocal glasses are a great option for people who want a wider lens area for computer work and reading.

Progressive Multifocal Lenses

Progressive multifocal lenses enable you to see clearly at different distance ranges through one lens. A progressive lens gradually changes power from the top to the bottom of the lens, giving you a smooth transition from distance to intermediate to near vision.

Progressive multifocal lenses do not have distinct lines or segments. They also offer clear vision over a large range of distances. This makes them a popular choice for many people.

What You Should Know About Fit Bifocal & Multifocal Lenses

After age 40, most people will experience presbyopia, a very common vision condition linked to aging. Typically, it becomes difficult to see objects close to your eyes clearly. Activities such as reading fine print or doing detailed craftwork become very challenging. Presbyopia is a normal part of aging caused by a loss of flexibility in your eye’s natural lens.

In the past, the classic treatment for presbyopia was to wear bifocals or reading glasses. However, a lot of people are resistant to putting on this unsightly eyewear. Fortunately, there are now alternative treatments that work just as well to correct presbyopia and provide crisp vision close-up. Multifocal contacts are a great option for many patients, and our eye doctors are experienced in fitting patients with multifocal contact lenses in Overland and St. Charles. Contact us to book your contact lens eye exam and fitting at our Overland Optical Family Eye Care office.

Contact Lenses for Presbyopia

Wearing contacts gives a level of freedom that glasses cannot achieve. With multifocal contacts, you can gaze in any direction and benefit from sharp vision. In contrast, with multifocal eyeglasses, you’ll need to move your eyes upward to see into the distance and downward to read a book. We offer a range of bifocal and multifocal contact lenses in Overland, including soft and rigid gas permeable types.

Bifocal versus Multifocal Contacts

What’s the difference between these two types of lenses? Bifocals are divided into two sections with different lens powers – one part for distance and one for seeing up close. With these lenses, you will be able to switch between far and near effectively, yet it may be impossible for you to focus on anything at a middle range away from your eyes. In comparison, multifocals have many built-in lens powers, thereby enabling you to switch between far, near, and in-between with more flexibility.

Types of Multifocal Contact Lenses

Multifocals come in a variety of designs:

1.Simultaneous Vision Lenses allow you to see both distance and close simultaneously – as the name states. After a rapid adjustment period, your eyes will learn to use only the part of the lens that is required for focusing on what you want to see.

Simultaneous vision lenses come in a concentric ring design and aspheric design. The most basic type is concentric, which is constructed with a central circle that has one vision power and an outer ring that has the alternate lens power. Extra rings can be added to form a multifocal contact lens, and the edges are blended to provide a smooth visual experience.

2. Aspheric design Lenses blend many vision powers over the entire surface of the lens. Lens powers for both near and far are situated in the central area, and your eyes will adjust naturally to use the part of the lens that’s needed to see clearly.

3.Translating/Alternating Vision Lenses are available only in hard, gas permeable versions. They are made with separate zones – top and bottom – and your eye will move to the necessary zone to see. Since contacts move around within your eye, these lenses are anchored in place with a thicker weighted area at the bottom of the lens, which aligns the lens with your lower eyelid.
