Calabria Hydrotac Dive OPTX 20/20 Stick On Bifocal Lenses Used for Scuba Masks/Diving Goggles Magnifying Bi-Focal Stickers

A little tricky to get ‘em in place to stay. But once you do they’re great. And they hold up. Just finishing 10 days aboard a liveaboard in the Philippines. 4 dives a day. Constantly rinsing out and defogging my masks. Not one problem.

Didn't really work as I had hoped especially for the price. They are smaller than expected. They did adhere to the mask and stayed in place. Unfortunately they hindered my vision more than improving. Obviously it was a longshotwhat, I mean what can you expect from stick-on readers. My review is more directed at the dive-targeted hype, the actual size and the price for a product that works as poorly as the cheap ones

Great idea, however they dont stick to my mask. Fell off when I was 30 meters down on a dive and I could see my gauges well.

These worked great on a week trip. No problems at all, just follow the directions.

I saw the reviews on this and had hope that they would work. I followed the directions and could not get them to stay on my mask. I'm sure they would have floated away on my first rinse of my mask so I decided to return them.

Only one dive with these so far, but love them! Follow the directions for install and all should be well.

So I was so skeptical this would stay adhered considering how often masks are washed out. However after a week of diving 3 to 4 times a day in the Galapagos Islands, they are still adhered to the mask.

I was going to use these for SCUBA, but when I put them in per instructions and rinsed out the mask, they came right off. So, that means if you get water leaking into your mask during a dive, they will float and maybe poke you in the eye.

helps me aee more under water
