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. 👍🏼

OK, I admit I did not try to use this product as intended. My ambitious plan was to glue this 2.5 diopter lens into my SCUBA mask so I could read my dive computer easier. I used (separate purchases) LOCA glue and a UV flashlight to glue the lens in, and then cure the glue. (LOCA glue is typically used to attach smartphone glass panels). The glue and UV light worked GREAT! - crystal clear! But the lens, used in this fashion was not worth a hoot. My dive computer was not easier to read - it was perhaps worse. The good news - I was able to pull the lens out and remove the glue so my SCUBA mask is back to square one. Onward to Plan B. Maybe this lens is OK when attached to your sunglasses, but NOT for a SCUBA mask, in my humble opinion... Tried my best, didn't work...

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!!!

Ever since losing the ability to use my "monofit" contact lenses, I have been looking for a solution to replace them. With my monofits, I could read with one eye and cope with distance vision with the other. Using my distance glasses and applying the OPTX20/20 lenses, I can place my reading distances in the spots I need them most. I use the +2.50 for close work and reading books, setting them at the bottom of my viewing area... and a +2.00 for use with my computer, which is a bit farther from my eyes, and locating them at the top of the viewing area.The only problem comes when I try to affix the HydroTac lenses too close to the edge of the lens of the glasses. In some instances, the HydroTac lenses come too close to my eye lashes, and the skin oils on my lashes paint a smear on the inside of my viewing area, requiring many cleaning sessions. Moving them down from the curvature of the main lenses will usually fix this problem.I know they make bifocals, trifocals, and all sorts of no-line lens enhancements for glasses, but these are quite cost prohibitive, and I can see just fine with this adjustment. I'm just lucky enough to use all plus diopter corrections, for both distance and close work. My monofit contacts were +2.50 and +5.25. With glasses and these OPTX 20/20 lenses I find I can back off on the corrections and see very well. Glasses are still a hassle for me, but OPTX 20/20 HydroTac lenses have reduced at least fifty percent of the hassle factor... or more.

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.
