You may only know that AR-coatings are mostly applied to eyeglasses lenses to reduce the amount of external and internal reflections on the lens, actually, they can also improve quality of vision by decreasing unwanted glare at nighttime, as the lenses increases the amount of light transmitted through the lens, and these coatings are especially beneficial for those who have strong prescriptions as they also make the lenses appear somewhat invisible and thin! What’s more, you can get them for free if you buy eyeglasses lenses at ozglasses.com!
