Optical Lens for Swimming Goggles
Intro: Optical Lens for Swimming Goggles
First, I removed two optical lenses from my old eyeglass.
STEP 1: A Cord of Sugru
Using sugru, I made a small adhesive cord that has a length which is equal to twice the diameter of each lens.
STEP 2: Hint !
Both lenses fit inside the underwater goggles as you can see from the previous images :)
STEP 3: Entourage
Surround the lens with sugru and apply pressure to fix it inside the goggles.
STEP 4: Optical Goggles Ready for Use !
.. and do your best to remove the additional sugru outside the frame . Finally, I have optical underwater swimming goggles :D

1. vertex distance, the distance from the lens to the eye.
2. pupillary distance and height, an optical point on the lens that's usually placed directly over your pupil.
3. "wrap" of your eyeglasses, the amount of curve in the frame as it crosses your face. The higher your script, the more significantly deviations from the original frame will change the power and resultant prism in the lenses. Folks with higher prescriptions are the ones who would most want to try this, just be aware that those higher prescriptions would require a careful choice of goggles in order to be able to see out of them. Also, I'd not trust Sugru to keep those lenses in place as water depth (pressure) increases. You could end up with a lens in your eye. Good instructional so long as these limitations are followed.

Thank you for your comment !
As you can see, I chose a goggle that has a frame which is very close to the shape of the eyeglasses. Also, it has different levels from inside, so that the lens will not fall at the bottom and it will maintain the vertex distance. There is an edge which facilitates the placement of the lens, and with pressure, it can be fixed without even using sugru. However, sugru will bind the lens and the frame and resists separation due to water or any other external factors. This method was applied for higher prescriptions and it seems that it is fully working.

Perhaps you'd want to get a set of lenses made for underwater use?

Please note that pre-made prescription lenses don't correct astigmatism, most people who have astigmatism can function quite well with a spherical (meaning "without astigmatism") correction in the water !
