I bought these in anticipation of my upcoming lasik procedure. These things look great and the seller even included a cleaning kit in box. As someone who is 6'3" with a larger head, these sunglasses are snug without being uncomfortable. I actually love that since my current prescription sunglasses are so loose on my head that they can fall off during light activity or when I sweat. Now that I have my pick of the litter with sunglasses, I could not be happier with the money I spent on these and the quality that comes with them.
