Great glasses at a great price. I never updated by glasses because going through the eye doctor was expensive, and i couldn't make a decision on what I wanted to invest in for the next couple years. With the low cost glasses that I get with KZFOO, I can purchase multiple pair, have different looks, and update my glasses more regularly. I went from only wearing my glasses when I needed to give my eyes a break from contacts, to wearing my glasses almost every day. Can't recommend this site highly enough.
