It's just Awesome product. The quality of lences is Amezing. It can fit to any spectacle or Sunglases. Attaching these reading lencesto spectacles is very very easy and once it is fixed properly, it remains on that position untill we want to detach. Thanks to Amezon, who made such a wonderful product available in India. Must buy, who requires reading lences.

nice item

This is the second pair I have purchased as I discovered I didn't get the right strength the first time. I bought these to stick on to my polarized fishing sunglasses and they work great. I cut them down to size and placed them on the bottom inner side. I had to fit them on twice as I couldn't get the air bubble out the first time.

EXCELLENT solution,--for my situation-- First I should say these attachable lenses are a WONDERFUL INVENTION & WORK PERFECTLY-(FOR ME). I'm THRILLED I found this option,--They were also not too difficult to apply-(it was a little hard to handle them) without getting my finger prints on them before they adhered to the glass etc., that was tricky & took some patience, as did the proper placement, but it literally took me no more than 2-3 attempts and in under 5 min I was done & reading perfectly!! AND NOW, having said [that] I should explain HOW I Utilized them to work for MY SITUATION!! ---I had a pair of expensive titanium framed eye glasses I never wore (it was just for a light stigmatizm) I didn't [really] require them to see,--([that] plus "vanity" prevented me from wearing them)--FAST FORWARD 25yrs later when I hit my 40's & suddenly I was BLIND as a bat (& couldn't read a thing!?)BUT I could NEVER find a pair of "readers" that weren't heavy, or hurt to wear! Then l saw these "stick-on-lenses" & remembered my old tiny titanium-framed glasses, I figured I'd give it a shot.(My glasses were quite small, I knew I wouldn't be able to use them at "the lower half"--but I figured It would cover most of the area of the eyeglass while not distracting my vision or being uncomfortable)SURPRISE! THEY WORKED PERFECTLY!! It Covered most of the area of my small oval-shaped-frames & were PERFECTLY USABLE & completely COMFORTABLE,--which was what I needed, comfortable, light-weight glasses I could wear all day at the computer in my house!,--woohoo! I'm Sooooo happy.*I would CAUTION anyone CLEANING these to do so VERY DELICATELY & CAREFULLY because they seem easily scratchable if the wrong material was used to wipe them clean!--(they are a semi-hard polymer plastic after all)... I intend to try another pair to use on sunglasses in the future... I think these are a great invention & fantastic option for ppl who need readers alone or in addition-to, but perhaps don't want "two" sets of glasses, or don't want to spend the (considerable) cash for bifocals etc. 👍🏼

First of all, the add says Hydrotac Reusable Stick-on Bifocal Lenses (OPTX) +2.00 Diopter. When you choose it you have to ask for 1 or 6 units. When add to cart, will chang fore a +2.50 Diopter. I ask for 6 units and only receive 1 unit of a +2.50 Diopter. Writen to the seller and Amazon for fixing, yet not possible to get 6 units of Diopter of +2.00.I tried the product on my dive mask, and did not work. Got fog in it, (mask did not have fog). And after the dive it did fell of and was unable to find it. Product not worth for scuba diving.Watch out, even if Amazon was advise of the situation of the change of product when add to basket, and after being told by Amazon that the product will no be on sale until situation fix, still there with the same situation.

I bought these reading lenses to put onto my expensive sunglasses. I followed the directions exactly however the lens does not seat onto the glasses properly. I tried to fit them onto my glasses three times. The first time, the edges lifted up so there was a small air gap making them unusable. On the second and third attempt, all kinds of small air bubbles developed under the lens...so it was like looking through fog. I would not recommend these.

These lenses are big and need to be cut down to fit most glasses. That is the difficult part. They are also a bit expensive for 2 pieces of plastic. The package appears to be more costly than the actual product. Once installed correctly they do work well.
