My glasses have a 94 uvb protection? what does that mean?

Question

I went to a sunglasses store and asked what could happen if i wear them and he said, that i'd probably go blind eventually. is that true?

I really really like them though. plus what would be worse, wearing those glasses or wearing none?

Answer 1

The store guy is trying to sell you more expensive sunglasses.  The ones you like should be just fine.  Unless you work outdoors or spend an inordinate amount outdoors then those should be perfectly fine.
