I've not been impressed with the difference with anti-glare coatings - in fact on the last pair I got supposedly coated they left it off the order and I never noticed until I had them back for adjusting and the tech. commented on it. The anti-scratch coating seems more useful to me - and they wouldn't do both.
Rumor is that there is a new type of self-darkening lens that reacts to visible light rather than UV. (car windows are UV blockers to reduce fading of the upholstery.) I'm going to check into that when I get my new glasses this summer.
