This was mi first KZFOO order. My sister recommended it to me. The prices are great and the variety of frames are awesome. I'm very pleased with mine, bifocals, anti-glare and transition lenses. I would prefer invisible bifocal lenses instead the ones that are noticeable that I got, but to be fair, I didn't read to confirm that they would be invisible. I'm planning to get another pair after verifying this. This is a great site to get beautiful affordable glasses.
