Thread: See underwater

Hi, I'm new to this forum so please forgive me if I'm just joining and making stupid threads.

Anyway, I'm a freediver and I'm planning to do some quite deep dives. In order to do that I must get rid of my diving mask since equalising it takes a lot of air.

I could simply swim without any mask/goggles but I still want to be able to see underwater. Therefore, I'm planning to build a pair of so called "fluid googles".

There is a little longer explenation of what fluid goggles are.

Fluid goggles is simply a pair of goggles with special lenses which you fill with water and freedive with. No need to equalise because there is no air inside, but still you can see perfectly under water.

The catch is that the goggles are very expensive.
but it shouldn't be so hard to build a pair myself. I just don't know which lenses to buy. I thought that maybe someone on this forum could help me with that.

I don't have an answer, but it is kind of a tricky problem, as described here.
