In reply to UKC Gear:
I saw this thread occasionally with surprise, I really appreciate UKC writes the review, it is really excellent, it talks about all the things we want to express, and also mentions the shortage of them. I also would like to thank the guys above to leave their opinions. However, I notice the misunderstandings and want to make a few rational explanations:
1. Necessity to use belay glasses: actually that is the matter of hobby, it is like gloves, without them you still have no threat to your life but they bring comfort, while I like the metaphor from Lucy Creamer more: "A bit like what it was like when seat belts became compulsory"

2. Compare to CU: at first to put enormous little difference aside, the biggest one is the nose bridge design, we have larger nose pads so it is more comfortable, that may bring little difficulty to be compatible with some fully-cover sunglasses. But for 100% eyeglasses and most sunglasses, they have perfect compatibility
3. To whom says we are copiers: design patent, No. 002433698-001, No. 002397745-001 protected by OHIM. The first car in the world was invented by Benz, but we have Rolls-Royce. It is unfair to say followers are copiers.
