Hydrotac Stick On BiFocal Reading Lenses Mens Womens Clear Magnifying Bi-Focal Reusable Reader Adhesive Stickers

O found these Hydrotac +2.50 stick pn readers to be am wxcellent product. They stick surprisingly well, and the vision they provide is clear, crisp and well focused.I.now a big fan for using these to make sunglasses.readera. Highly recommend.

I’m a repeat customer. Several times over. They’re perfect for my inexpensive sunglasses (for biking and paddling). I highly recommend these.

I purchased these hoping I could use them on some off road goggles as readers. I cleaned the surface of my new goggles and followed the instructions by wetting the lenses and installing them. THEY WILL NOT STICK. There is no- one side is adhesive, and the other is not. I tried looking through them and they are cloudy and foggy and have no magnification properties. I tried different distances from my eyes and it made absolutely no difference. Do not Buy!

It takes awhile to get the hang of how to cut and set the lens so that it does not dry with air bubbles. Tip one is use lots of water and don't press it out too hard or too fast. Let the lens get tacky and then gently put it into its final position. Then gently press the excess water out and slide the lens to make small adjustments. Tip two is make sure to measure your center to center distance using an existing pair of bifocals - and use that as a guide for positioning the lens on your target glasses. This is not a replacement for sunglasses or cycling glasses with a bifocal option, i.e., Maui Jim makes awesome bifocal reader sunglasses. A built in bifocal is far superior to stick on lenses. However for one piece lenses like the Smith Pivlock or the Tofosi Podium these readers are fantastic.If you have sunglasses or sports equipment where there is no bifocal reader option then I highly recommend these lenses. Just remember to get at least 2 pairs so that you can practice on one set of glasses before working on the pair you really care about. Why can't they come out with a peel off sticky lens? I have no idea. However with patience and practice these are a life saver so that you can see your cycling computer or GPS.

I did not find any other solution to have bifocal cycling glasses. Can not read Garmin navigation display without eye glasses. I would have preferred to stick on from inside rather than out side due to wind resistance. Only the top sections is usable to read, I had to cut 40% from bottom to make it usable. I selected the location where my bifocal eye glass have inserted the reading section. Following the instruction is easy but not easy to stick them on. Hopefully it will stays on when I start cycling

As my eyes start to age I've had to switch back and forth between reading glasses and sunglasses if I needed to read anything while wearing sunglasses. If you've ever done this you know it's a pain! I recently discovered bifocal reading sunglasses and that led me to these stick-on lenses! "If these work", I thought to myself, "then I could transform my expensive decades-old sunglasses into reading sunglasses!" These lenses were easy to adhere, easy to remove and adjust, and stay put! I put them on an old pair of polarized Nikon sunglasses and they worked great! I did, however, trim them down a bit on the bottom curved edge so that they didn't sit directly in my line of sight. I then went on a 14-day wilderness trip where I encountered all kinds of weather, wind, water, blowing sand, sunscreen, etc. Not only did the Optx lenses stay in place, but they were easy to clean with a microfiber cleaning cloth. However, some sand did stick around the edges especially between the Optx lense and the edge of the frame. But, when I got home I was able to easily clean the sand off with water and mild soap in a much less hostile environment. I am going to get a couple more pairs to transform my decades old Raybans into reading sunglasses! I'd highly recommend these lenses! For the price, it beats having to buy expensive sunglasses all over again!

Great if you need a bifocal lens on a pair of non-prescritipiton sun glasses.

I bought these and put these on a pair of my favorite sunglasses. Over the period of a week they fall out three times, the last time I didn’t even find one of the lenses. Just note these do not adhere well at all to the glasses and will fall out easily. The value for the money is very poor, they are expensive yet easy to lose

When it sticks it very good but I find it don’t stay on my glasses very long

The size of the lenses has been drastically reduced. Why. I liked them when they were the original size, slightly bigger. They are too small now

Muy util para poder leer con lentes obscuros

Exactement ce que je cherchais pour mettre dans mon masque de plongée. Solution simple et peu onéreuse et efficace. Collée avec de la glue spéciale verre, ça fait le taf !

These are great. I use them inside my lamp working didymium glasses. It was painful to wear my sight glasses under the lamp working glasses, prescription didymiums are horribly expensive and so are the fit-over glasses, so I gave these a try. I have had no problems with them falling off, as other buyers have. For my personal use, they would have been nice slightly bigger, but they do the job very well. Very pleased with them for the price.
