A few questions for the folks who may know more than me about this subject.... 1. In general, will prescription lenses of the same type be a little darker than non-prescription lenses... For the simple reason that they may likely be a little thicker? If so, I'd like to take this into account when making my selection. 2. Same ole question, new student. I have narrowed down my choices to the G30 iridium polarized and the VR28 black iridium polarized. They will be going in my pair of Minute 2.0's. They will serve as my everyday, all day sunglasses for general use, with golf being my primary hobby/sport, followed by bass fishing in south Louisiana. As best I can tell by looking through sample lenses at Lenscrfters, there is not a world of difference between the two, although the vr28's appear to be just a shade darker (no pun intended). Any advice from you general users out there to get me off the fence one way or the other? 3. Are either one of these notably better than the other at the beach, in brighter light and more glare? I suppose the specs would suggest the vr28's would get the nod here. 4. Another question for the 100th time... Is either one of these lenses definitely gonna hide my eyes any more than the other from the outside? I would prefer that my eyes not be visible.. Well guys, thanks in advance for any input you may have. Need input quickly though, my frames are in the mail headed to the Oakley shop in CA.
