OPTX 20/20Stick-On Bifocals, +125

They didn’t stick to my diving mask. They didn’t stick to my sunglasses either. They definitely don’t stick. I carefully reviewed the instructions and checked videos on YouTube, but they just don’t stick. Don’t waste your money. I wasted mine, including the shipping cost to Chile. I don’t recommend them.

Well, been old for a while, but now there's proof based on my Amazon purchase history. But regardless of the march of time, this has proven to be a very handy product.I use it with my current glasses (put them on a spare pair) for reading small print, such as newspapers and some magazines (which, for some reason, always seem to want to print things in 8 or 9 point type when it's clear that most of their readers are well over the age where they can read such small type. Then they wonder why circulation is falling.)Sorry for going off on a tangent. Back to the stick on lenses. They work great. Had no problems putting them on my glasses. The pack did not come with directions, but directions were available on the manufacturer's web site. Basically, clean your glasses well with very warm water, then soften the stick on lenses with warm water, stick them on, push out any air bubbles, and let them dry. The lens have a curved side which is the side you want to affix to the glasses.So far zero problems with them coming off. Clarity is excellent. They are noticeable on regular glasses - I expect they would not be noticeable (or hardly at all) if you used them with sunglasses.Lot less expensive them progressive lens and, for me, work just as well. I can clearly read the newspaper again!Highly recommend.

I actually ended up putting them upside down after another reviewer recommended it. I put these on a basic non prescription blue light blocking set of glasses I use for working on my computer, and I found that the round part being up gave me better vision for my screen use and the flat part down worked fine for looking at my phone or reading something on paper. I moved them around a lot until I settled into where i wanted them placed. One thing to pay attention too, they go on the inside of the lens with the outside curved portion of the magnified sticky (convexed) attaching to the inside (concaved) eyeglass lens. A little too pricey for what it is, but its the cheapest alternative to what I wanted.

The product that I received was optically very poor quality. I followed all the instructions for adhering them to my sunglasses, was very careful to clean them, and the result was that looking through them made the image blurrier. Not in the way of a smudge or a wrong focal strength, but in the way of being warped and non-spherical. Yes, I did adhere them in the correct direction in the correct orientation. I think they are just poorly made.It is very frustrating that the item is not returnable. I am now out $15 and have no recourse.

I have used these lenses for 7 months now, and I am very pleased with them. I put mine on a pair of 1.75 diopter reading glasses to make my own bifocals. So for distance I have the 1.75 correction and for reading I have 3.00 correction. They work just as well as the prescription bifocals I replaced, at a much lower cost. I trimmed the bottom edge of mine so that it followed the rim of the glasses better. They were very easy to trim with a good, sharp pair of scissors. I wet the lens and placed it on the corresponding lens of the glasses. I used plenty of water so that the lens floated until I had it in the position I wanted it. Then I pressed the water out from under it, dried the glasses off, and have used them since with no problems. I drop my glasses too much and these lenses have never loosened or come off. I did notice the right lens developed a bubble in the center after a few months, but I just peeled it off and re-stuck it. The left lens has stayed completely sealed all the way across.

These stick on bifocals used to be absolutely wonderful! But when the first set gave out (wouldn't stay stuck to my glasses) this is now the 3rd set I've purchased (thinking maybe it was just a glitch) and each time they will not stick to my glasses. The edges of them always curl up and not lay flat like the 1st ones I bought. These were the best thing I've come across in years, now they don't work for me any more. So disappointed. Won't try again. :(

You have to be really careful that you press them on securely.And not sure how it happend but one got damaged somehow and lens became cloudy.tI wasn't something I could clean off it.They should also be a bit smaller as they cut into the direct line of vision.You can buy cheap reader sunglasses in TJMax, 2 pair for about $12 dollars and that's what I ended up doing.They do work well however for reading.It is nice that you can use your expensive sunglasses and turn them into readers.

I have bought 3 of these now, the 1st one didn't stick but I thought perhaps it was me so I bought another and it did stick. It is pretty great on the glasses I have it on. So I went for another since I was at 50/50. It didn't stick again, so at this time I would recommend that you dont waste your money on these. And the no return policy is garbage, this seller should be ashamed as they are clearly aware of the unreliable nature of this item.
