Non-Glare or “AR Coating” Eyeglass Lenses

Non-Glare or “AR Coating” Eyeglass Lenses are really a high tech way to get the best performance out of your glasses. The foundation of non-glare lenses is a scratch coat layer that can lengthen the life of your lenses and reduce the amount of surface scratches from daily life or cleaning. The lenses are similar to coating found on microscopes or camera lenses. Even the latest equipment used in our practice has non-glare properties. Did you ever wonder why you felt you saw better during your eye examination than with your new glasses? It may be just as simple as the lenses you purchased did not have non-glare coating.

Non-glare lenses consist of several layers of metal oxides applied to the front and back lens surfaces. Because of the layering effect, non-glare lenses sometimes have a hint of green, blue or purple color, depending on the individual manufacturer’s formula. Each layer is scientifically calculated to block reflected light; they also reduce both internal and external reflection on the lenses themselves, creating a nicer cosmetic appearance. Internal reflections appear as rings that make lenses look thick. Eternal reflections mask your eyes from a clear, complete view when someone is looking at you. So with a non-glare lens, reflections are eliminated and lenses look thinner or non-existent and your eyes are more visible so you can make a better eye contact with others. Not all non-glares are the same and the properties that allow more light to reach the eye or the cleanability vary tremendously.

At D’Ambrosio Eye Care our preferred brand is Crizal Avance with Scotchgard™ Protector. These lenses allow 99% of light to reach the eye, improving contrast sensitivity by 20%. The scratch coat layer is applied to both sides of the lens, where others only apply this layer to the front. There is a “hydrophobic” surface layer that prevents water spots (rain, snow and fog) and makes the lens very easy to clean. The “oleophobic” surface layer repels skin oils, smudges, dust, dirt and fingerprints better than leading competitors. These lenses have superior anti-static technology. After 20,000 cleanings this non-glare lens has 98.2% durability, meaning the benefits of the lens do not lessen over the life of the lens, preserving the premium qualities. Other non-glare lenses breakdown over time. Even the value non-glare package at D’Ambrosio Eye Care is 80.1% durable.
