Ok, I've decided to buy some rayban aviators to cover up the cavernous pits that my eyeballs hang out in. I thought that it would be pretty simple to pick a pair of gold aviators, but they didn't have many in the NEX and I got overwhelmed looking at raybans website. You guys have any suggestions for me to look into? Is there any particular lens that is the best? Do you guys like the ones where the ear pieces are straight back or the ones that curve and go behind your ears? Also, what's the deal with those ones that have the plastic bar over the nose? is that supposed to keep them from slipping off or something? I'm just looking for a good place to start
