In the glasses is eye protection, which is, however, to use as a sports sunglasses. I use them for cycling and am generally satisfied with the purchase. Punk deduction is available for the occasional slippage of the nose, and my nose is not exactly small. A separately purchased Neoprene Brillenband now ensures the necessary support. Very pleased I am with the undisturbed field of vision, so that one is inclined to forget that you ever wears glasses. Also commendable is the anti-fog coating of the lenses. Even during strenuous bike tours, where I have been sweating heavily, the glass remained clear inside. Also easily designed with me to use along with a helmet - there really is nothing to disturb. This requires you to note that my head is not exactly small.
Conclusion: Ordinary sports / goggles at a fair price. People with small noses / heads need to take any loss in comfort in purchasing.
