OPTX 20/20HYDROTAC Stick-on Bifocal Lenses +250

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. 👍🏼

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.

Good

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.

They work great, but if you take them off (one actually fell off) they no longer stick.
