When it comes to the particular features of your eyeglasses lenses, a number of optional treatments are available. Anti-reflective coating is one feature that our optometrist strongly recommends.
What is AR Coating?
Just like scratch-resistant coatings, anti-reflective treatments consist of a thin, yet very hard film of metal oxides that is layered onto the front and back of your lenses. Each of these layers is made to block reflected light.
For your prescription glasses, 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 reduce any glare that could disturb your vision.
When Does AR Coating Help?
In general, anti-reflective coatings help you to see better through the lenses of your prescription eyeglasses and sunglasses at all times. In addition, other people will be able to look into your eyes without seeing their own reflection in your eyeglasses! There are certain circumstances that AR coatings are particularly beneficial:
