They do not work. They fit well, felt great, however, they did not meet my 1,75 needs as stated. Non-adjustable - I can't imagine how they can work for very many. Price is fair if they would just perform as claimed, but they failed big time. Plus they did not provide the MICROFIBER case or sleeve they recommend you to store them in, which they implied they were included, however, both boxes did not provide anything but papers and glasses. They fit better than my prescription frames, I really wish they worked as stated. So this is why they suck!
Bottom Line: No, I would not recommend this to a friend
