Back-glare is a common problem that affects people who wear prescription eyeglasses or sunglasses. Described as light that hits your eyewear lenses and bounces into your eyes, back-glare can affect the quality of your vision, as well as be an irritating nuisance. Anti-reflective coating eliminates or diminishes these reflections off the lenses.
Our eye doctor will check your vision during a St. Charles eye exam to determine if you require prescription eyewear. Once you have an up-to-date and accurate vision prescription, it’s time to choose a pair of frames and eyeglass lenses to suit your vision condition and lifestyle requirements. A number of optional lens treatments are available, and anti-reflective coating is one feature that our optometrist recommends.
In the same way that a scratch-resistant coating is applied, anti-reflective treatment consists of a thin, yet very hard, film of metal oxides that is layered onto the front and back of your lenses. The index of refraction lies between glass and air, which means that the light intensity reflected from the outer surface and inner surface of the film is almost equal. Reflections from both sides of your lenses thereby cancel each other out and minimize any glare that could disturb your vision.
In particular, our optometrist recommends AR for patients with a high vision prescription or astigmatism. It will allow your eyes to appear more natural behind your eyeglasses. Other people who benefit greatly from anti-reflective lenses include those who work in a bright office space and/or gaze at a computer screen for extended periods. When you drive at night, you’ll also appreciate how AR reduces glare from oncoming headlights.
With AR coating, you will see better through the lenses of your prescription eyeglasses and sunglasses. In addition, other people will be able to look into your eyes without seeing their own reflection in your eyeglasses!
To preserve the durability of anti-reflective coating, you must clean your lenses only with solutions recommended by our optometrist. The technology of this lens feature is advancing constantly – providing crisp, higher quality sight for all vision conditions.
