Correct me but isn't it so that wooden goggles work simply because they are incompressible?
I am sorry, but really not. You have to realize that the atmospehric pressure is inside the goggles, but not inside the eyes that are in the goggles, hence the sucking effect and risque of hemorragy or burst capilaries in eyes at goggles. You woud need rigid "goggles" completely enclosing your entire body, keeping it under the atmospheric pressure, for allowing your argumentation.
It works with the wooden goggles, because of their shape that is more round and bigger than common swimming goggles, hence allowing the eyeballs going deeper into the cups, compensating so the inner volume (and hence the pressure too). Common swimming goggles are mostly smaller and additionally they usually have a silicon skirt that prevents the eyeballs from entering into the cups easily, hence hindering the volume compensation.
I tested the wooden goggles, and at some 6 meters my eyeballs touch the glass. I can descend to some 8m but not deeper, because the contact becomes very unpleasant. However, with a better fit, you could go deeper.
The goggles are really beautiful and a very nice piece of equipment for collectionners, and I encourage you to get a pair too, but if you want to dive with them, you should be aware that the eyes will be stresses anyway, and that the glass used is plain glass (no tempered glass), that can easily break and cause serious injury, especially when your eyeballs are in direct contact with the glass.
