Anti reflectioncoating

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.

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.

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.

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.

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.

Vision problems caused by prolonged computer use are common. A 2020 study published in the journal Cureus reported that computer vision syndrome—a condition characterized by headache, itchy eyes, and temporary vision changes—was higher in eyeglass wearers and those who reported glare on their computer screens.

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.

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.

EKSMA OPTICS neutral density (ND) filters attenuate VIS spectral region. The optical density varies from 0.1 to 3.0, 1 or 2 inches size square and roud shapes are available.

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.

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

Antireflective glasses vs blue light

Neutral density absorption type filters decrease the intensity of light without altering the relative spectral distribution of the energy. They are used to filter the entire visible spectrum evenly, allowing light reduction, without influencing color or contrast. Attenuation is accomplished by using a light-absorbing glass.

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.

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.

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.
