This is the latest iteration of my fluidgoggles. I choose this goggle model (Cressi Sub Galileo which is the noseless version of the Cressi Minima) because:
- The lenses are in line which gives a better vision
- The goggle covers more of my sinuses
- There is enough room to fill unused space with silicone for cold water diving
- The goggle is big enough to attach lenses on the inside for good vision on the surface too!
The silicone also helps keeping the lens distance holders in place. No glue is required so it's easy to cut out some of the silicone, re-adjust the lenses and put new silicone in again.
I assume this can be used in competition too because identical lenses are used as in other fluidgoggles. Maybe some of our resident judges could give their opinion about this?!
OK fellow freedivers, I come here with good news. Final solution for great goggles is here! It is confirmed, tested, nice and simple. It comes from Anchor Optics and it catalog number is:
Anchor Optics - Commercial Grade Plano-Convex Lenses (PCX) , Uncoated
From all different lenses and companies this particular one is by far the highest quality finish and sharpest image. How sharp is it?
I see clearly underwater to the point that I read smallest digits on my Suunto!
I had it both in pool and lake and it works great, couldn't be happier about it.
Few pictures below:
1) Product package and number
2-5) Process of making - aquarium silicone used to glue lenses. Weird lever thing is basically weight needed to keep goggles flat and leveled while glue was drying.
It is OK to glue lenses outside goggles using one drop of glass glue (super glue kind) but field of vision is compromised. Same sharpness but less view.
Mounting lenses inside, flat side towards eye gives better field of vision.
I have them so close I touch them while blinking but I am fine with it.
There are two problems with zinc sulfide:What would be the downsides from using a zinc sulfide lens except the price?
