The Journey is the Reward

"Do you know how cool you have to be to wear these frames? That’s what I was telling myself every time I tried them on. I finally excepted that I am that cool. I love the frame shape and color and how it balances my face. I’m really happy with Caddis eye appliances, I was going to get LASIK before I found your frames."
