I could not get the lens to properly adhere to my glasses no matter what I tried. I'm pretty handy/mechanical and get most things to work. Not this item! I read the instructions, watched YouTube videos, got telephone advice from the manufacturer customer service twice and no luck. I feel that there was enough difference in the curvature of the inside of my glasses compared to the outside of the "stick on" lens combined with the rigidity of the stick on lens that the water adherence process could simply not overcome. Maybe they work/stick properly with different glasses/prescriptions/stick on lens diopter combinations, but not with my case. Had to return.

OPTX 20/20 Hydrotac Stick On Bifocal Lenses +1.50 Diopter | Magnifying Adhesive Reading Lenses | Sunglass Magnifier Add On | Reusable DesignFirst impressions: Nice set of two plastic flexible lenses to attach to your glasses, prescription or not. The lenses add a bifocal section on to the inside of your glasses, which they can be prescription or even a pair of sunglasses.Installation/setup: Follow directions to attach to the inside of your glasses. Be sure to apply to clean glasses, and let them dry completely.Final thoughts: I had success and a fail. I got these to put on the inside of my sunglasses I use to ride motorcycles. I got them on, let them dry, and they stuck pretty well, allowing me to see menus and read instructions pretty well. Not as well as my prescription bifocals, but enough to get by during a ride. Unfortunately I didn’t think about the wind rushing across the lenses and possibly pulling them off the surface. And that’s just what happened. I was wearing these, I didn’t have my face shield down, and turned my head just enough to lose one of the lenses. In conclusion, learn from my experience and beware the strong wind lol.⭐️1 star - I don't recommend it at all, poor quality.⭐️⭐️ 2 stars - I don't recommend it, it has multiple faults, or a very high price.⭐️⭐️⭐️ 3 stars - It's passable, It has some faults but the quality is ok for what it is.⭐️⭐️⭐️⭐️ 4 stars - Product quite acceptable, it does what it promises.⭐️⭐️⭐️⭐️⭐️ 5 stars - Product that I totally recommend.

I just ordered our 4th set for my wife's next sunglasses. We have tried other brands, but none stick like these do (you do have to let them dry overnight), and we experience zero clarity issues.Bifocals are a must for me when shooting pistols (reloads, malfunctions, gun handling, etc), and these allow me to make sunglasses & clear shooting glasses into bifocals for much cheaper.

These may or may not work on flat lenses, but they will not stay in place with wrap-around style sunglasses. I tried them both inside and outside the lenses, and no dice. Yes, I verified that I had the on right side out.

I tried to adhere the lenses to two different pairs of sunglasses. The lack of flexibility inhibited full lens contact. The upper part of the lens is quite thick and would not conform to the lens (note: the lens of the glasses does not have a large curvature). Additionally, the magnification power seems to be miscalibrated and did not provide proper viewing (less than the package specification).

Worked great

I like the concept behind these stick on reading lenses. They are designed to turn any pair of glasses into bifocals. I am reaching that age where I need reading glasses, but my favorite pair of glasses only correct for far sight which means I am constantly taking them on and off when I need to read something up close. I was hopeful that I could use these to turn them into a nice pair of bifocals and take care of near and far visionThis comes with one set of two stick on lenses. They are designed to sit at the bottom of the lenses, so it works when looking down to read or look at a phone, but they can be trimmed to preferred size. The instructions are easy enough, just wet the lenses, stick on, wipe away excess moisture, and let dryI cleaned my glasses lenses to make sure it was a clean surface, and followed the directions, but I couldn't get them to stick on. No matter how much moisture I tried, they would simply slide off. I let them sit and dry a few times to give it another go, and they simply wouldn't stick. They don't seem to contour well to the shape of the lenses, so the sides start coming up and then they just fall offI love the idea, but they just didn't work for me
