TUSA Sport Optical Lens Mask Insert

For the price point this works great. The optics are obviously inferior to an expensive mask with your custom prescription, but it's not bad for what it is. I am nearsighted and also have bad astigmatism and could see fine. If you already have a single lens / full face mask this will work. It does not fit in the masks where the left and right lens are separated by plastic though. If you don't already have a suitable mask and need to buy a mask to use with this, you would be better off just getting an optical mask such as the Promate.

They won't work with EVERY mask;But overall they're a great option for divers want some temporary (but not perfect) vision adjustment. But don't want to pay hundreds for a true RX mask/inserts.I'm nearsighted -2.0 (can't drive without glasses) and they work great!

I just used these yesterday while snorkeling in the Caribbean. I was so happy with them. They fit very easily in the mask that my tour provided me (so I'd imagine they'd fit in most masks, as these seemed pretty basic). The first time I used then, I forgot to defog them, so there was water between them and the mask. Second time, I defogged both the mask and the clip in lenses, and both were completely clear the whole session. I'd highly recommend these, as they're much cheaper than buying an Rx mask, and you'll actually be able to see what's in the water!

Great product and enables my son to go exploring in the waters without having to be blind underwater or at the beach thanks to being able to just insert these into the goggles he already had.

Your lab or mine could not put my script into this frame. Not good for anything other than a basic script

its ok. not sharp

Make sure your mask supports this design! Your mask must be a one glass piece mask. Also, these get kinda push against my eyes which is annoying.

Works great for snorkeling 👍
