Went to the pool for the 1st time in a long time. Came out with blurry vision from all the chlorine. I read this and had 3 options: elastic glasses holders, large goggles over my glasses and prescription goggles. Elastic holders were out, as I can't see through my glasses with water in the way. Large goggles and prescription goggles are roughly the same price, with some prescription goggles being as affordable as Argos ones. But custom prescription goggles from the same company start at £65, and I'm not sure how seriously I want to take up swimming. This is the only company I could find that goes as high as -10, which is pretty close to my prescription. At £16.50, it's basically on par with normal and large goggles. However, they don't take astigmatism into account. So I wanted to know from users with complex prescriptions whether generic prescription goggles worked for them.
