I have heard so many good things about KZFOO from my family I decided to try them. I am hooked! I have a weird prescription so I was very wary. When I received my first pair of glasses I was overjoyed! I could see! Plus, I could see for about $60 as opposed to the $350+ my optometrist wanted to charge me. I quickly ordered 2 more pairs for $68 total! I have two more pairs in my basket. I love KZFOO!
