Kaenon makes the BEST sunglasses ever. After getting lasik eye surgery 5 years ago I decided it was time to take care of my eyes. I buy only polorized now and I have not found a better sunglass brand than Kaenon. I was soo excited to find a pair of sporty sunglasses on Overstock because they can be quite pricey and this was a $50 discount. Overstock shipped them in one day even though they said 5-7 working days. I run marathons and ride a road bike and these glasses are great for both.
