How to Choose a Prescription Lens Scuba Diving Mask

Scuba masks can be ordered with prescription lenses to make underwater photography and reading gauges and dive computers easier. Cave diver and Technical Scuba instructor Jill Heinerth tells us how she sets up her dive masks.

Jill you are an INCREDIBLE human being, greetings from my wife (Canadian from Toronto) and I from Palermo, Italy

It would be nice if you provided links to the products you discussed in the description.

Hi Jill.
I would also like to know where you send your masks. I live in Waterloo ON and it seems the closest places are in Cali and Florida.
BTW, I really enjoyed Into the Planet. I am in Mx for my Cave intro in 2 weeks.
Keep the videos coming!

How am I supposed to know how high I want the bifocal line if I have never done this and its $250 for a set of lens. I would have to pick the wrong height and have to remake them.

Hey Jill, could you provide links to companies that do built in reader? Thx

I order one from amazon, and my prescription is really simple. I don't need a bifocal. I will never dive or swim without an RX mask or goggles. Water act as a lens so I order -4 instead of -5 by the suggestion of my optometrist

Hi Jill. thanks for the video. A few things I want to mention from personal experience. the glue in lenses you mentioned that you no longer use- I tried them. although inexpensive, I found in warm tropical areas, the glue became undone and I lost one of the lenses when came back on the boat. I also had bifocal prescription lenses done (my dive shop has an optometrist that does it), it is ground directly in the lens- very, expensive (several hundred dollars). Do NOT do this with Atomic masks- I love the mask, but cannot pop out the lens and replace if need new mask and want to keep the same lens. I would be interested if you can tell the viewers whee you got the bifocal part done so we can make own inquires.

Hi, thaks for your video ! I have a question, do you add a bit of like 0, 25 or 0, 5 diopters to underwater lenses than used on land ? I use +2 and I have noticed that underwater with the same mask I see a bit worst.

This segment was labeled how to choose ... I was hoping there would be a from lesson.
There wasn't any information on who makes these handy dandy bifocals.
