Previously I was paying $300+ for my bifocal glasses from a box store. I found KZFOO on the internet, looking for a less expensive alternative. I was pleasantly and happily surprised at the quality and beauty of the glasses I received. I was so happy that I bought a second pair of glasses and had them made into sunglasses. A huge bonus was both pair cost approximately half the cost of a single pair of glasses where I used to go.
