Question:
Could a pair of clip-on sunglass lenses be worn on a pair of sunglasses to provide additional UV protection?
Answers:
All commercially made sunglasses should be 100% UVA and UVB protected. There would be no reason to wear clips over the frame. The only thing that will do is make things so dark you won't be able to tell what you're looking at.
