Each AR coating manufacturer has its own proprietary formula, but generally all anti-reflective coatings consist of multiple microscopic layers of metallic oxides of alternating high and low index of refraction. Depending on the AR coating formula, most lenses with anti-reflective coating have a very faint residual color, usually green or blue, that is characteristic of that particular brand of coating.

By eliminating reflections, AR coatings also makes your eyeglass lenses look nearly invisible so people can see your eyes and facial expressions more clearly. Anti-reflective glasses also are more attractive, so you can look your best in all lighting conditions.

This was a birthday gift for my husband and he loved them! They look very nice and sleek keeping away the sun rays without sacrificing visual acuity

I bought these in brown tortoise with smoke lens over a year ago and they are wonderful! They are super lightweight and the polarized lenses are awesome. I get tons of compliments on them. I love them so much that I just ordered the blue tortoise ones and they are super cute!! These are my favorite sunglasses I’ve ever owned.

This is probably my 6th or 7th pair of optic nerve sunglasses! They look great and fit perfectly!! I always rec this brand to my friends :)

"...I’m a new fan of Optic Nerve and will be buying their eyewear for many years to come. I also ordered the Fixie Max Mirrored and am looking forward to testing them out as well. I’m sure I’ll be equally as pleased with my purchase now knowing just how good these Fixie Stealths are."

Some eyeglass lenses have factory-applied AR coating on both lens surfaces. Other lenses, particularly progressive lenses and other multifocal lenses (i.e., bifocals and trifocals), have the coating applied after the lenses have been customized to your eyeglass prescription by an optical lab.

I have Macular degeneration and needed sunglasses that give extra protection from the sun and the wrap around sunglasses seem to do that. I received my sunglasses today and the fit was perfect. Thank you Opticnerve

These have great coverage for fishing, skiing, biking and beer drinking. Basically everything. Price is right on! Perfect

Both benefits are due to AR coating's ability to eliminate reflections of light from the front and back surface of eyeglass lenses.

We bought our first pair from a store and the second directly from the brands website. We love the Kingfish sunglasses with the brown lens. Ultimate visibility for bowfishing murky/green waters. It's seriously like having XRAY vision. We have recommended this pair to ALL of our friends that come with us and every bowfishing group we are in on social media!

How to make your glassesantiglare at home

The first step in the AR coating process is to meticulously clean the lenses and inspect them for visible and microscopic surface defects. Even a tiny smudge, piece of lint or hairline scratch on a lens during the coating process can cause a defective AR coating.

The visual benefits of lenses with anti-reflective coating include sharper vision with less glare when driving at night and greater comfort during prolonged computer use (compared with wearing eyeglass lenses without AR coating).

Anti-reflective coatings are incredibly thin. The entire multilayer AR coating stack generally is only about 0.2 to 0.3 microns thick, or about 0.02 percent (two one-hundredths of 1 percent) of the thickness of a standard eyeglass lens.

For example, regular plastic lenses reflect roughly 8 percent of light hitting the lenses, so only 92 percent of available light enters the eye for vision. High index plastic lenses can reflect up to 50 percent more light than regular plastic lenses (approximately 12 percent of available light), so even less light is available to the eye for vision. This can be particularly troublesome in low-light conditions, such as when driving at night.

Purple is my favorite color. These sunglasses are nice for the price and hold up well. Wish there was some more colors though

I just ordered my 3rd pair of these glasses. I initially got them for hiking because they are so lightweight and stay in place. I find that I've stopped wearing my other sunglasses and just wear the Alpines all the time. Really comfortable on my face.

Applying anti-reflective coatings to eyeglass lenses is a highly technical process involving vacuum deposition technology.

Today's modern anti-reflective coatings can virtually eliminate the reflection of light from eyeglass lenses, allowing 99.5 percent of available light to pass through the lenses and enter the eye for good vision.

Anti reflective coatingmaterial

Typically, a production line includes multiple washing and rinsing baths, including ultrasonic cleaning to remove any traces of surface contaminants. This is followed by air drying and heating of the lenses in special ovens to further remove unwanted moisture and gases from the lens surface.

While the lens racks are rotating in the coating chamber, a power source within the machine focuses a beam of electrons onto a small crucible that contains a series of metal oxides in separate compartments. When bombarded by the beam of this electron "gun" in succession, the metal oxides are transformed into vapors that fill the coating chamber and adhere to the lenses in a specific order to form a precise multilayer AR coating.

These fit a little large, especially for smaller faces. But great glasses at a even better cost! I love that Optic Nerve is Colorado local. They also have an awesome customer service team.

Great eye protection, from damaging sun or when working. The polarized smoked lens make natural colors appear more saturated but not corrupted. When coming inside from outside, the transition is not abrupt and you will not need to take the glasses off to see comfortably. I like that feature especially in public. Lens resist scratching and clean nicely. Great price! For me best overall I ever owned.

The lenses are then loaded into special metal racks with spring-loaded openings so the lenses are held securely but with virtually all lens surfaces exposed for the coating application. The racks are then loaded into the coating chamber. The door of the chamber is sealed, and the air is pumped out of the chamber to create a vacuum.

Also, don't attempt to clean AR-coated lenses without wetting them first. Using a dry cloth on a dry lens can cause lens scratches. And because anti-reflective coating eliminates light reflections that can mask lens surface defects, fine scratches often are more visible on AR-coated lenses than on uncoated lenses.

AR coatings are especially beneficial when used on high-index lenses, which reflect more light than regular plastic lenses. Generally, the higher the index of refraction of the lens material, the more light that will be reflected from the surface of the lenses.

Most premium anti-reflective coatings include a "hydrophobic" surface layer that prevents water spots from forming and makes the lenses easier to clean. Some AR coatings also include an "oleophobic" surface layer that repels skin oils and makes it easier to remove smudges from the lenses.
