The size and shape of the lenses may determine what pair of swimming goggles will fit the best.



First, put the goggles on, and hold the lenses up to the goggles to check if you can see well with them. Ideally the lenses should be close to the same distance away from your eye as the eyeglass frames originally held them, and this quick test will determine if you will be able to see well with them once they are glued on.



The lenses should at least overlap the frame of the goggles on the left and right sides. This is the minimum amount of glue area that you will need, as shown in the pictures of the clear goggles below. In this case, the top and the bottom edge will be open, allowing water to flow freely between the glasses lens and the goggle lens. This is probably the easiest and most reliable solution.



If the lenses overlap the frame all the way around, as shown in the pictures of the pink goggles, then the glue can be applied all the way around. This will created a sealed space between the glasses lens and the goggle lens. There needs to be as little moisture trapped in the space as possible to prevent fogging, so this should be done in a dry place, or you can apply some anti-fog to the lenses on the inside of the space. Also, the glue needs to be properly applied to prevent leaks.



If you are going to buy a pair of goggles, you may want to remove the lenses from your old glases first, take them with you to the store, and see if they would fit well over the goggles.
