    Good refraction, dodgy coating.

    In general these are great, and I can now safely walk to the pool edge, avoid other swimmers and read the poolside clock. In general they are pretty watertight, but this is obviously subject to user competence when fitting them. One goggle leaked a little (my fault) but when I very gently used my finger to stroke the water away the coating started to move immediately and clouded the lens. I think I will be able to fully remove the coating with a cloth but this was disappointing. I had seen similar problems mentioned in a couple of the reviews, but most seemed fine so I ordered.

    Prescription Swimming Goggles

    The cardinal rule with goggles, as highlighted in our order leaflet is to never touch or rub the inside of the lenses.
    As you have found, it is an extremely thin film that coats the inner surface and is easily disturbed.

    Nice quality. The goggles come in a case . Need to be super careful to avoid obscuring the lens/goggle. Probably avois chlorinated water sticking to lakes and sea. Great service from the seller.

    Good decision

    Wearing my glasses in the pool meant I could see properly but I found that the chemicals were affecting my eyes. Now with prescription goggles I can swim with my head in the water and still see where I am going without having eye problems. So glad I bought them.
