So previously I have been swimming with no glasses or contact lenses and just goggles which was a bit fuzzy but doable. But my eyesight is getting worse. Today I wore my contact lenses with my goggles (took them out and binned then straight after) and being able to see clearly was amazing!!! So I was thinking of buying some prescription goggles but are they any good, where do you get them from? I had a quick Google and there are loads of places selling them but some are really cheap, others pretty pricey. Any advice?
