I believe the anti-glare has more to do with how you look in glasses than functional reduction of glare to which you are subjected. I wear very strong lenses, and anti-glare reduces the surface reflection of light, mostly keeping people from noticing that I essentially have magnifying glasses strapped to my eyes.
High index does significantly reduce thickness (for which my ears are profoundly thankful). Photogray is pretty easy to detect, and mostly saves me from needing sunglasses. All lenses start out round and are cut to fit frames. That means if they are embedding bifocals they have to know the final shape in advance in order to place the crystals correctly. Rectilinear shaped frames tend to necessitate shorter distance between focal center and bifocal. Tricky to make, but this also reduces the "coke-bottle effect" of strong lenses. Those of you who have seen my glasses and think I am delusional about the effects of these "extra features" should see what I look like in the cheapest possible lenses...and I can't wear cheap glasses for long because my ears hurt from supporting them. One more thing about price...there is such a thing as badly made glasses. I also have astigmatism, and some percentage of lenses I receive if not properly made, cut and mounted will give me headaches and have to be re-done. Since I pay a fortune for them I have no qualms requesting this action. A last consideration...I have more than one pair of glasses at all times. First, I am functionally blind without them (which means if break or lose a pair, I can't drive or read or even find my toothbrush without them). But also? You wear them ON YOUR FACE. How many pairs of shoes do you own? Shouldn't your face deserve some variety as well?
