Hydrotac Stick On Bifocal Lenses +1.50 Diopter | Magnifying Adhesive Reading Lenses | Sunglass Magnifier Add On | Reusable Design

These worked great for my husband. He uses them on his sunglasses so he doesn’t have to wear his classy black readers on the tip of his nose while wearing his sexy Maui jims. They stayed stuck as intended for over a year until one fell off whilst the glasses were dropped. No fault of the product.

I purchased these OPTX 20/20 Hydrotac Stick On Bifocal Lenses +1.50 Diopter, and I can not recommend them. The package was not sealed when I received them, and one of the lenses was scratched. I thought I would try them anyway and see if the scratch affected my vision. I followed the instructions of cleaning my sunglasses, warming the bifocal lenses, and applying them with a few drops of warm water. I had a hard time positioning the lenses on my glasses because they kept sliding around when I tried to push them down to remove the air bubbles. When I got the lenses in the proper position, I let them dry overnight. When I put them on in the morning to test them out, everything was blurry, and I saw they were only stuck by a thin strip across the center. I touched one lens and it popped right off. The other one came off with a slight push also. There was no way these were going to remain on my glasses for long. Just to be sure it was the lenses and not me, I tried again to apply them. Still no success! The description says they work on any glasses, but they did not work on my new clean sunglasses.

These needed to be cut a bit to fit correctly for me. They are simple to attach and they stay reasonably well. But be careful as I found they come out with sometimes a simple touch or cleaning.

Stick like glue even without water. They work pretty well

I really wanted these to work. I've got some nice Oakley's but am in need of a bifocal like magnification for reading. There aren't many brands out there for these and this brand says made in USA, which was great. Except they don't work. It's possible that the curve of the Oakley lens is too much as these are quite stiff for what they are. They are also relatively thick. I tried installing them multiple times in varying locations on the lenses but could never get a full "adhesion" to the Oakley lens. The part that did adhere was also a bit blurry. I believe if they were thinner they might work as it would be a bit more conforming. Not sure if that would help with the clarity. I got the +1.50 but am returning them.

Do not try to affix these to sport-style wraparound sunglasses. They are not flexible enough to conform to that shape, and can't seal to the plastic. So they fall off easily, and when you're out on a bike ride, you can't just stop and pick them up.

The biggest problem with these are that it is very hard to get them to sit cleanly on the glass. Bubbles are created in the field of vision that distract the clean view. The lens itself works well as you can see if you just hold it up without attaching to the glass. However good luck getting it to sit cleanly on the surface. So i am using them but there are blurry spots in parts of my vision--which is annoying. The company needs to give some advice on how to get it to sit on the glass clean and even. Then they would be a great product. ***EDIT-- I bumped it up to a 4 because you can get used to the imperfection...but they still are a great invention!!!

So these are 👍 great. They are clear,crystal clear! Easy to install. They stay put. You can remove them and install in other glass. They don't seem to scratch easily . The material acts like vinyl with a lense in it. You can trim them to fit any glasses. A sharp pair of good Scissors ✂️ will do the job. They come in all strengths so be sure to check that box when you order DO NOT PAY $38.00 FOR THESE. They are readily available for $19.00. Last, be careful cutting to size I got one backwards the first time. ✌🏽♥️

Funcionan razonablemente bien, un poco complicado colocarlas en el lugar adecuado para que sean de utilidad. Es un proceso de prueba y error para dejarlas en la posición óptima.
