Anti-Reflective (AR) Coatings are designed such that they would allow more light through, whereas a normal lens would reflect about 20% of the light hitting it. Not only this improves the optical quality of the lens, but it will make your lenses look better, since reflections off of normal lenses will make it harder for people to see your eyes.
Another advantage of AR coating is that it will reduce halos and glares around bright objects at night (such as headlights of the incoming traffic), thus improving the night vision significantly.
Ultimately more light into your eyes and less glare will reduce eye fatigue and strain.
At LensOnUs, our high quality AR has even more coatings than usual that would provide extra benefits. These additional layers will make the lens more scratch-resistant, will block more UV radiations, and will make the lens harder to smudge and easier to clean (thanks to an extra hydrophobic coating).
