If prescription eyeglasses are purchased today, chances are the lenses will have an anti-reflective coating. This coating will not only improve vision, but will also improve how the glasses look on the face. Someone looking at a person with the anti-reflective lenses will not see a blurry effect on the lenses. Often the position of the sun will totally obscure a person’s eyes if they are not wearing glasses with anti-reflective lenses. If they are wearing glasses with the coating, looking at their eyes will be as clear as if the person were not wearing glasses.
The coating, often called AR coatings, is made of layers of metal oxides that are applied to both the front and back of the surface of the lens. Each layer will block reflective light, which results in the reduction of the glare effect and eye blur. The layers of anti-reflective coating can also be applied to the back of sunglasses, since clear eye contact is not so important when wearing sunglasses. Even being applied just to the back of the lens will reduce glare.
For those who wear the light, thin high-index lenses, the anti-reflective glasses are better since thinner lenses reflect more light. When the anti-reflective lenses are on the glasses, not only will the light-weight glasses be more comfortable to wear, they will also result in better vision day and night.
Benefits of Anti-Reflective Glasses
Working on a computer each day can cause eye strain. The glare from the computer screen can make it difficult to see, resulting in eye strain. Wearing lenses with the coating will cut down on the glare and ease the eyes. Since the anti reflective coating on the lens also reduces glare, they will eliminate the halo-effect around car headlights, which is a benefit when driving at night.
Taking Care of Glasses
The anti-reflective glasses should only be cleaned with special micro-fiber cloths purchased from an optician, as small scratches are more visible on the lenses. Wet the glasses first and use a dry cloth to blot them dry. Cleansing products with harsh chemicals can ruin the coating.
