unisex-adult Hydrotac Stick-on Bifocal

My co-worker told me about this product and I ordered it right away. I wear contacts for distance,and I was so tired of switching my sun glasses for my reading glasses. Now that I have put these on my sunglasses, I don't have that problem anymore. I was impressed by the quality. It's much thicker than I imagined. It was really easy to put on. Simply put a drop of water and it sticks. If you need to move it or re-position it, you can easily do that as well. It's a bit big for me, so ideally I would need to trim it to size. However, it doesn't bother me much, so I've left it. UPDATE: Today I wore my sunglasses with the stick-on bifocals and I LOVE IT!! I can see the dash when driving so much clearer and I can text on my phone and actually read what I'm texting instead of just 'blind texting.' I'm recommending this product to all my friends!

I have, or have bought, about 8 sets of these over the years that I use for non-prescription sunglasses in my car and on sunglasses I use for cycling. I have been using these for at least 5 years. I have sets that have been on glasses, in the sun, for at least 3 years and they have never fallen off or otherwise become unusable. I replace them only because when I (rarely) take them off the glasses to clean the glasses (after thousands of miles cycling road grime) I notice that they yellow over time in the sun. Like ski goggles, I don't ever notice the yellow tint, but every now and again I like to start fresh. I always have at least one spare set of new inserts in case I destroy a set of glasses or buy an additional pair. I keep these in my Amazon cart and usually pick up a pair when there is a temporary price drop. I only wear reading glasses, but at the 2 to 2.5+ level, and can't read my car gauges or my cycling computer without readers or these inserts. These work very well for me for driving and cycling. Hopefully, my eyes will stay about the same for the foreseeable future, and if they do, I will continue to apply these to all my sunglasses. If they don't? Well, I'll cross that bridge when it happens.

As a distance runner and cyclist, I use a number of sun glasses, some of them with interchangeable lenses. Unfortunately, I also need near sight vision correction. Buying prescription sunglasses in the quantity I need them would simply be cost prohibitive. These Stick-On-Bifocals are a perfect solution for this situation. I can use any sunglasses I want to and convert them easily in prescription sunglasses for a very low cost. I think it is a perfect solution. I would have given the product five stars. However, there are a few potential adhesion problems. With one pair of interchangeable lenses, I can't get the Stick-Ons to stick at all; they simply fall off every time I try. With another pair of lenses, the Stick-Ons stay in place but tend to gradually come off at the edges over time. No real problem, though, I just push them back in place with water while cleaning them. Overall, this is fantastic idea and very low cost solution for a problem I had for years. If you have a near vision correction need, this is the answer. Are there some potential adhesion issues? Yes, but for me the benefits outweigh by far the occasional issues. With this in mind, I can highly recommend this product.

These are very low quality stick-on bifocals. They are not very flexible, they scratch extremely easily, and they do not stick well on glasses that are not completely flat. I have used other brands that are far superior. I would prefer to pay more for a higher quality product. Since posting the above review, people have asked me where they can get higher quality stick-on bi-focals. Unfortunately, the place I bought mine 5 years ago is no longer in business. Instead, I now purchase bifocal safety glasses. I have been very happy with the DeWalt brand as well as a less expensive brand sold by MFASCO. Both are sold on Amazon.

These are ok. Kind of difficult to get them to adhere to the lenses without air bubbles underneath. They do work and after a couple days playing with them I got them to stick without bubbles. But I think they are a little big for my lenses and kind of in the way of visibility. They do work for reading and I’ll probably leave them on for a while to see if I get used to them. Short money and worth a try.

Over the past 10 years I've gone from +1.5 to +1.75 to +2.0. I've tried stick-on lenses from other companies, and none have worked as well as the Hydrotac lenses. I now have them in three pair of sunglasses (driving sunglasses, bicycling sunglasses, and yardwork sunglasses). Bottom line: I think they are overpriced but they work well, so I pay the price and enjoy them.

These totally solved a long standing eye protection wear problem. For Search and Rescue we wear eye protection in the woods but still have to read GPS or map and compass. I wear reading glasses. The comedy of hauling out readers, swapping eyewear, wiping away fog on the readers, battling fog on the (now cold) eye-pro when putting them back on... was driving me (and others) totally nuts! Bifocal eye-pro is out of the question - you're tripping over everything. I added a SINGLE lens INSIDE one side of the eye-pro. I'm truly delighted with the result. My eye-pro never leaves my face so cooling and fogging are not an issue. (The added lens does not fog up when placed inside.) My eye-pro is made from polycarbonate. No issues with adhesion. I am used to monovision. (I wore monovision contact lenses for years until suddenly for some reason my eyes would not tolerate them.) Prescription lenses for wrap around eye-pro are not doable and slip-on side protectors for prescription glasses have proved unreliable, resulting in eye injuries in our group. I keep the spare lens together with a lens towelette in a small plastic bag in my map pouch just in case.

Have used them in the past with good results. This last time I just couldn't get them to work, maybe it was the curvature of the lenses or a defective pair, but couldn't get them to adhere properly without bubbles in the middle top side of the stickers. After trying multiple times just had to throw them away. Shame as I love the concept.

Buen producto

These are fantastic. I can finally wear cool sunnies again. Just make sure you let it take hold properly before using or getting them accidentally wet. Try to avoid water. Really good value for money especially when compared to the US Amazon site, where many items are jacked up to a ridiculous price as soon as they are put on the Australian Amazon site, these are a pretty fair equivalent. Thanks to the seller for keeping costs honest.

Really good just the job

Mit den Linsen kann man jede Sonnenbrille oder Fahrradbrille für wenig Geld in eine Lesebrille verwandeln.

These are not as good As I expected but are just about acceptable.
