I know this has been done before, but I'm going to put a couple of new parameter on it. I was diagnosed a while back with age related macular degeneration (AMD dry) and drusen. I've been taking A-Reds and eating fish as much as I can. I don't think it's progressed much. I also had cataracts and had the first surgery a couple of days ago and looking to do the other one in a few weeks. The change on the fixed eye is amazing. I already can see better then I have in years, it may get to the point it's the best I've ever been able to see. UV is the biggest contributor to AMD and makes it worse. On the sunglasses, I'm going to need a wrap around style to keep as much of the sun knocked down that I can. I wear a Shoei Neotec II with the drop down visor, but it doesn't come down far enough to not need sunglasses. I'd like the straight legs in order to make it easier to put them one after the helmet is on. I'm thinking that even though I'll be seeing better, I don't think I'll be so lucky as to not need cheaters for map reading, etc. So on whether they are polarized or not, I'm thinking not. I have a very nice set of Maui Jims now that are polarized, and when the polarized shield is down and you have the polarization on the GPS and TFT displays, things get pretty wonky. Maybe someone with more technical knowledge can help with this. Let the over analyzing games begin.
