Calabria Hydrotac Dive OPTX Stick On Bifocal Lenses for Scuba Masks and Diving Goggles | Water Activated, Reusable Readers

Loved using these in my snorkel on my last vacation. I was able to actually see the ocean life up close. They are removable which was a plus because I didn’t like the first mask I tried so it was easy to transfer them to a second mask. I highly recommend!

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

Unfortunately I waited until after the return window to open the box. One of the lenses is warped and has what almost seems like a melt mark on it, in addition to a milky residue in places. Won’t rest flat on the inside of my mask at all. The other one rests flat, but also seems to have a bit of milky residue. I’m glad I purchased a bifocal mask as a backup, because it doesn’t look like these will cut it.

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.

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.

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.

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

helps me aee more under water
