OPTX 20/20 HYDROTAC 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. 👍🏼

Well after several attempts of cleaning and applying these lenses following the instructions to the letter, I have come to the conclusion that these lenses are complete junk and a huge waste of money. They only stay on for about an hour. They are completely useless. Its your money if you want to try them but I'm sure you'll be disappointed. I threw mine away!

I purchased a couple pairs a few years ago. The stick ons work well once you get use to them. I use them for Cycling. I wish they were slightly bigger. It takes a little while to adjust to the edges. They do work.

Work great on my sunglasses. The size of the lenses does affect the optimal location as does the distance apart. The beauty is that these can be moved around when first wet (or subsequently if desired) to ensure best visionary plane. I buy expensive sunglasses and cannot, with aging, changing prescription, buy prescription glasses. This product negates the need for prescription eye protection, but enables me to see the car dash. My ophthalmologist did test my eyes for best number to get based on the distance to the dash, which is different than if I were reading a book or doing computer work. So the lenses were actually 2.25 instead of 2.75. Not saying this would be the norm for others but it works fabulously for me. In a store when I forgot my other glasses in the car, it was not easy to read the ingredient label with the lesser magnification.....so I've learned to either not try to read ingredient labels or to have a small magnifier in my wallet (credit card size and very thin) I can resort to.

These give great closeup vision IF the curvature of your glasses already matches the curvature of these lenses, but mine are only a so-so fit. That means that these lenses tend to lift away from the lens of your glasses, and there is no vision correction in the areas of the lens where they are not full adhered.

Being an optician for 20 years and having used stick on prism for patients this was very easy to install. I wanted a 2nd frame color from Zenni optical so only got the free single vision lenses ( planned to just swap the progressive lenses to the frame color i wanted as needed). These will not help much for computer, etc work but on my tinted single vision lenses they are the bomb! I went up a bit on power and can see detail and read like an eagle. If you have good distance vision and are tired of carrying around sunglasses and readers then get these, follow the directions and put them on your sunnys and just like that you only have to carry the sunnys and you can still read. 100% would recommend!!!

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.
