About 2 weeks ago, I went to the bowling alley and left my sunglasses on the counter behind my uncle while he was sitting down watching. I am not sure what happend to my sunglasses. Either someone stole them or I left them behind by accident. These had no scratches, no nothing and fire iridium mirrored lens. I have severe eye problems. I have had a detached retina on my left eye, then the operation gave me a cataract then I had to get the lens removed and then I have scar tissue there. In my right eye, I have had a partial detached retina and had to have the top and bottom done with a laser. About a month ago, I didn't put my sunglasses on and I went outside about 10 feet to the car. I got into the car and then shut my eyes and I saw a big black splotch. I opened my eyes and say a whole lot of black lines and 1000's of dots. A long story short, that was a drop of blood from my optic nerve having a small hemorrhage. In this past month I now have a posterior detached vitreous that is giving me problems seeing. So I need the best pair of sunglasses on the earth bascially because I am so allergic to light. I got on ebay and was being a cheap ass and bought a pair of new oakley badman ferrari sunglasses from a dealer that never sold but been on ebay for 3 years. He was selling 5 pair at $122 each free shipping. My eyes hurt going outside with those. I think they are fake because they weigh 1.0 oz compared to the 1.4 of the real ones. Now I am forced to buy some x-metal ones again and have to go through ebay. I was wondering if I should buy new from there or used. Even if I buy new, the sunglasses can be 10-11 years old. I have heard from 1 seller that the lens can start to peel after 10-11 years. (mine didn't). But if I buy new I don't want them peeling. ANother option is that there is a seller, selling the ones I have that has the receipt, and he just got new lens put in along with all new rubber parts about 2 months ago. Oakley doesn't make anything this good any more so I don't know what to do. I was wondering should I buy new or is used fine? I appreciate any comments..
