Hey Pablo,
I have prescription goggles but I only use them in the pool. I am blind as a bat so I used to wear contact lenses whilst swimming but I found my eyes dry out when swimming in the pool. I bought the Aquasphere Eagle Goggles which comes with regular lenses that can pop out and then I also bought two of the goggle lenses to pop in instead of the regular ones. Total cost came to €47 from Sean in Amphibian King West.
These are great in the pool, no complaint whatsoever except that they are a little large compared to the kaimans. However I don’t use these in the open water as they currently do not have a tinted version of the prescription lenses. This was fine for me as I only wanted them for the pool anyway and then use kaimans in the sea as I usually wear contact lenses in races.
Hope that helps!
