I wanted first of all to try whether a prescription swimming goggles brings anything before I buy a pair of glasses for 30 or 40 and then has no effect. 7.50 you can get over there. But the glasses my expectations fully met, it is dense, it fogs not, no burning eyes from chlorine after diving, it sits well and - I see while swimming back more than a couple of round balls on the surface. And also that you can see so much under water, I could not imagine a blind fish. The reviewers who complain here about the fact that the spectacle is only suitable for small noses, really need to have large teeth, because the strap, with the spectacle is supplied, fits my nose well. And I'm not a Chinese or Asian with very small nose. It took a week after shipment confirmation, until the glasses were delivered. Delivery is from England, probably because the postman has a rowing boat across the English Channel, because it was not the first article, which came from England and as long (or longer, up to 3 weeks) has taken. So is not the fault of the dealer, because the shipping confirmation I received just one day after the order. For my purposes (3-4 times a week swimming 1.5 to 2 hours) is the goggles very appropriate, I can only recommend.
