Corrective lenses for diving

**UWSojourner** · 2nd November 2006, 21:02

I ordered a mask from SeaVision and ended up returning it. For me the corrective lense took up far too much of the mask. I just wanted a very small area used.

I got these stick-ons and they've worked well for me (and they're cheap!).

Anyone else find this? Cos if I go for a proper bifocal lens, presumably the problem would be the same wether it was a sea vision, oceanic or tusa mask?

Part of the problem is that people don't carry these lenses in stock and noone who sells them on the internet even has a proper picture of a bifocal lens. That's why the sea vision guage reader appeals to me. At least I can see what it looks like

OK so I got the mitts / dry gloves issue sorted. Now looking through the Vision manual the sight test has provoked me into dealing with the recent deterioration in my eye sight. Having had perfect eye sight all my life I found myself with + 1.00 reading glasses. 18 months later, it's a + 1.75 dioptor prescription. How does this translate into underwater vision? Should I go for bifocals, or a straight + 1.5 lens? Anyone tried the stick on + dioptor lenses? There doesn't seem to be a lot of guidance out there! Can anyone help?

Having tried lots of masks, I settled on the Mares Xvision - very low volume and extremely comfortable. Bifocals (bonded lenses) are available from Mares but I had to order mine through an Italian dive shop in Rome (I was there anyway so had a bit of fun in the process) as I was told they weren't available in the UK. The lenses are reasonably priced at 32 euros a throw.

Apples and Oranges....

If you have that age old problem of getting far sighted....I have it too....and the only real problem is reading the gauges....check out a plano convex lens from Edmund Scientific or Anchor Glass. Get one less than 1 inch wide and glue it in the bottom of your mask. In some of my masks I have glued it in the inside...some the outside. Both work. One drop of clear epoxy will do the trick.

Mine have stayed glued for at least 5 years and I can see the gauges quite well now. During decompression, they also allow me to watch the swimming plankton.

I got buy with stick in lenses for about 7 years after I noticed that I couldn't read gauges underwater. This happened before I needed reading glasses on the surface. I got by with cheaters (above and below) but started to realize that I was suffering distance vision also. I could still pass my drivers licence test but things were not clear anymore.

It is the diving that got me in to the optometrist for a prescription. I actually ordered a prescription mask before I bought glasses. Since the main reason we dive is to SEE stuff, in retrospect I wish I had done this sooner.

With glasses my corrected vision is 20/15. After making the leap to a prescription mask I would not do it any other way.

I have the gauge readers from SeaVision. I must say that the lens work is spectacular.
My backup mask has glued on lenses. They are okay. However, the SeaVision (I have the clear lens model) is very high quality. There is a definite difference.

I have a -4.75 & -5.25 plus bifocals & I really like the Sea Vision too. Very light weight (composite resin material, CR-39, similar to Polycarbonate lenses). They can match just about any prescription & the masks fit well & are comfortable. Mine is four years old & still in great shape.

I used to use this outfit.
Welcome to Prescription Dive Mask

Another trick is to get the mask with script pop out lens and then mark your pupils and remove the lens and have them ground at your optometrist.
IF they think you handing them blanks they are alot easier to deal with.
Prescription mask $300, Hand them the blanks- bam your done.
