Anti-reflective coating on eyeglasses is designed to reduce glare, making nighttime driving easier, and reducing eye strain from computer use. The coating is fused into the surface of the lens, giving it a very faint blue or green tinge. Despite their benefits, anti-glare glasses tend to scratch easily and would then need to be replaced.

Anti-glare glasses also may help people who are sensitive to light while driving in the daytime or those boating in bright daylight. AR coatings are available for sunglasses too.

It's worth asking your optician about other available AR coatings. Manufacturers are constantly updating their materials and may offer superior products specifically designed for night driving, sports, or computer use.

According to Vision Center, AR coating can add $20 to $150 to the cost of lenses. Insurance may cover some or all of that cost.

While it's not an outright necessity, anti-reflective coating is something you may want to consider if you have symptoms of eye strain or spend a lot of time in front of a computer.

The coating is made up of carefully calibrated layers of metal oxides that are applied to the front and back of the lens and then irradiated with high-intensity ultraviolet (UV) light to enhance their light absorbency. This reduces reflected light and allows more non-reflected light to be transmitted through the lens.

AOA Xinetics has preserved and improved critical deformable mirror technology for nearly 20 years. The lead magnesium niobate (PMN) electroceramic actuators used in the mirrors have characteristics ideal for precision adaptive optics applications. The commercial deformable mirror product has not only helped astronomers see the very beginnings of time, but has also helped ophthalmologists see the very beginnings of eye disease.

Yellow-tint glasses often touted to improve night driving vision, haven't been shown to be all that effective in clinical studies. Anti-reflective coating, on the other hand, does reduce glare and can improve nighttime driving performance.

In the past, anti-reflective coatings were either painted onto the lens or applied to the lens like a sticker. But that's not the case anymore. Today, anti-reflective coatings are fused onto the lens matrix, a technology first employed with high-powered telescopes and microscopes.

If you are considering anti-reflective coating, check the grading scale offered by your optician. Some opticians offer a choice of "good," "better," and "best" (or a similar scale) with the "best" grade costing considerably more.

AOA Xinetics makes several different active optical devices to enable the optics community to dynamically control the focus, tip / tilt and high / low order wavefront errors found in uncorrected optical systems. All of AOA Xinetics active devices are based upon internally fabricated PMN co-fired actuator stacks or custom PMN actuator geometries. Tip and tilt mirrors are available for high-speed beam steering and/or wavefront tilt compensation. Each deformable mirror comes complete with a driver electronics system and interface hardware to enable the stroke and temporal response required. AOA Xinetics has built and delivered more than 200 mirrors totaling over 25,000 actuators in its nearly 20 years of business.

The American Optometric Association lists eyeglass lens coatings as one of the more useful solutions for computer vision syndrome.

Anti-reflective coating on eyeglasses costs more, but it may be beneficial in specific situations, such as night driving and preventing eye strain from computer use. On the other hand, the lenses are easily scratched and may require replacement.

Anti-reflective coating (also known as AR, no-glare, or glare-free coating) reduces glare by absorbing and redirecting reflected light. This allows more non-reflected light to pass through, leading to fewer visual disturbances. Unlike reflective lenses with mirror-like finishes, anti-reflective coatings are transparent with a very faint green or blue tint.

Glare while driving at night is a common cause of accidents, especially for people with astigmatism. This eye disorder, which affects one in three Americans, can cause visual disturbances like halos and "whiteouts" with approaching headlights.

Even so, a higher-end coating can be well worth your money. In addition to the benefits, these lenses tend to have better warranties and may be replaced at no charge if your lenses are scratched within a year.
