I had intra-lasik over 16 months ago, and I cant begin to tell you how important it is that you get a good pair of sunglasses. At this point, if i'm driving or outside and the sun is out, I have sunglasses on. Without it I find myself having to squint because everything is so damn bright.
I wear Arnette by the way. I have been wearing Arnette glasses since I was a teenager, and plan to continue wearing them as long as the company is in business. I think they are great.
PS- Aviator Sunglasses are really corny.
