OPTX 20/20 Hydrotac Stick On BiFocal Reading Lenses Mens Womens Clear Magnifying Bi-Focal Reusable Reader Adhesive Stickers

I barely write reviews, and I'm buying from Amazon almost everyday. I bought a meta rayban Gen1. Didn't want to spend the extra $250 for bifocals glasses so I gave this product a try. It works great. They never come off, even though I clean my glasses 100 times a day. I don't have to switch to my reading glasses anymore. Ordering another set for my daily sunglasses.

WARNING: CANNOT BE RETURNED. Perhaps it was just my seller,but I tried to return these and they refused. Nowhere in the product description do I see mention of these not being returnable. First time this has ever happened to me on Amazon. Review: I just got mine and, as I feared, I cannot aim my eyes through them to see the computer -- have to tilt head back so far its not practical. The only thing I have found them to be good for is to be able to look at my iPhone while I am watching TV, which is something I do frequently. Also, I have had some problem with their sticking to the lenses securely. I followed the instructions on a youtube video and got them to stick, but the slightest tap and they will pop off. For years, I have considered getting bifocals, but I figured they would not work for me the way I need them to, and this purchase has convinced me I was right. Tilting my head back just doesn't fly for the computer. So in a sense, these saved me a bunch of money buying real bifocals I simply cannot use. I purchased some clip-on "magnifiers" which work quite well for my common scenarios. They also have their drawbacks, but on balance, they work for me much better than bifocals will.

I've used these and similar stick on bifocal lenses for years, ever since I first started to need reading lenses. I live in Hawaii and am a runner, and you'd be surprised how often visitors to Hawaii stop me and ask for direction while I'm running, often with a map in their hands. With these lenses on my sunglasses I can read even the tiny print on those maps and usually help them out. I literally use them every day, and not just when I'm running, but anytime I'm outdoors. They adhere with a drop of water, and stay put even when washing the glasses with soap and water. If you ever replace the sunglasses or something happens to them (other than losing them) you can easily remove the bifocal lenses with a fingernail and use them again on the next pair. I will say that once they are in place on the sunglasses for a while they will leave an outline after you remove them, so I don't recommend moving them from one pair to another frivolously. All in all a great solution for a common problem. I strongly recommend them.

Good for sunglasses & such. Not a replacement for REAL eyeglasses though.

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

These worked like a charm. I had invested a great deal of money in name brand sunglasses and since I needed readers, the glasses were a pain to take on and off. Now I can read phone and small print without having to remove glasses all the time. Just a tip to pass on...to place the lenses properly, I put my glasses on in front of a mirror and marked my glasses where my eye naturally wants to look for reading. Then I cut the stick on to follow the contour of the bottom part of frame. Drop of water and they hold amazingly well. Amazing product that literally saves thousands of dollars to have reader sunglasses!!!

I have a nice pair of Gentle Monsters I wanted to convert to bifocals after having cataract surgery. These stick-on lenses were simple to apply and work very well. I followed hints from other reviews and just dipped the stickers entirely in warm water before applying. I didn’t end up with any bubbles and I didn’t even try hard to avoid them. My sunnies are Flatba style and have little or no curvature to the lens, so I applied the stickers “backwards” with the concave side down onto the lens surface. They seem to have slightly higher magnification than they’re supposed to, as other reviewers noted, but I wonder if it’s because I installed them the way I did (and if the variation reported by others is due to variation in the curvatures of the lenses they’re being stuck to). Either way, they work fine for my purposes, which included being able to read my phone or books while I have my favorite shades on. These stickers are awesome.

I received a single pair and both lens had slight scratches on them when I held them up to the light before applying them. They’re basically loose inside the plastic packaging. I went on and used water to apply them to the inside of a pair of glasses. One stuck and the other wouldn’t. They’re cheap plastic (why they easily scratch) and worth $5.99 not $19.99. I’m not new to using these type of stick on bifocal chips. So it’s not user error. I simply can’t recommend these at all.

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 !

Wie beschrieben mit einem Tropfen, meint ganz wenig Wasser aufgebracht und fest angedrückt (!) halten die Linsen in der Taucherbrille super. Dies gilt auch wenn die Brille permanent naß ist und auch nach mehreren Tauchgängen. Jetzt kommt der Wermutstropfen. Da die Linsen aus Kunststoff und damit hydrophob (wasserabweisend) sind, neigen sie in der Taucherbrille zum Beschlagen. Trotz den guten optischen Qualität habe ich sie deswegen wieder entfernt. :-((
