I searched the forums for this answer, but had no luck with the specifics. I need corrective goggles in the (+) plus diopter range...plus 2 to be exact. I only found one goggle offered online that is a positive diopter...for farsighted people. Corrective goggles are all over the place online, but they are for nearsighted people...almost exclusively. I tried a very bulky +2 goggle lens and it provided very clear vision, but they are not good racing goggles. Ideally, I would like to get the Speedo Vanquisher goggle in my prescription. These are my favorite google for comfort and fit. Thanks in advance.
