If anti-reflective lenses were not worth it would they be incorporated into your expensive binoculars, telescopes and camera lenses?  High index lenses can reflect approximately 12 percent of available light, thus allowing just 88% of light available to the eye for vision. This can be particularly troublesome in low-light conditions, such as when driving at night. Modern anti-reflective coatings allow 99.5 % of light to pass through the lenses and enter the eye thereby virtually eliminating the reflection of light from eyeglass lenses.

Anti-Reflective Lenses

AR coated lenses improve both vision and the appearance of your eyeglasses due to the coating’s ability to eliminate reflections of light from the front and back surface of eyeglass lenses.  Benefits of lenses with anti-reflective coating are sharper vision due to less glare when driving at night and greater comfort during prolonged computer use.  Anti-reflective coating also is a good idea for sunglasses, because it eliminates glare from sunlight reflecting into your eyes from the back surface of tinted lenses when the sun is behind you.

Advances in the coatings continue with new “media” coatings that help with the blue light that emanates from smartphone, tablets, and computers.  Most coatings now have a scratch coating built-in along with anti-smudge properties, and the tendency for some of the older coatings to “flake off” has also been corrected and eliminated.

If it is important for high-end optical products like cameras, scopes, and binoculars, shouldn’t it also be just as important for your eyes.
