Special lenses for mask?

[TexasKaren68]

Another +1 for the DiveOptx lenses. They came in a set of two but I just use one, stuck to the inside of my left mask lens. Works perfectly for reading things close up and it hasn't come off while diving yet. It came loose once when someone other than myself put defogger in the mask and messed it up, but once I got it home and got everything cleaned, it stuck perfectly a second time and hasn't come off since.

Bonus - looking through that part of my mask makes the fish look much bigger

Bare makes The Duo B mask and you can get corrective lenses for them for an affordable price... the mask are extremely comfortable... And you wont be paying hundreds for a reliable proscription mask.. The shop I work for sell the mask for $45CAN and $60 for a set of prescription lenses...

Thanks for the suggestion, but I would prefer something that I can stick directly to a gauge face, not inside my mask.

I'm sure you could somehow rig this up to your computer face. If you punch in 'Fresnel lens' into your search engine, millions of options come up. About $7 for two.

Curious as to whether these Frenzel lenses will work immersed in water

They're cheap enough to do a little experimenting.

Interesting. Now the question becomes "How do I affix them?".

If there is a good solution, which won't destroy the face of my SPG, I'll buy them for experimental purposes.

Thin bungee cords ? Wire ties ?

Like changing a wrist mount computer strap to bungee? Attach the Fresnel at four corners with bungee?

I wonder if that would cause the Fresnel to concave too much, if that makes sense? I'm not sure how flexible the stuff is?

I used Optx 20/20 stick-in lenses purchased at Walgreens. They are the same as the DiveOptx lenses - I mean EXACTLY the same, made by the same company. But they sell for $7.99 instead of $30. They worked just fine for ~300 dives over three years or so.

That said, last year I went to contact lenses, mostly due to need to see dive and bicycle computers. Highly recommended.
