Wow what a strange revelation,I havent opened my eyes underwater since I was 13-14 years old. I have always been afraid of loosing my lenses when swimming at beach or in the pool. but after trying to open my eyes with my head in a bucket full of water,I se now that there is noting to be afraid of

I culd look around,blink and not lose the lenses.
What a weird thing to find out at the age of 34 ha ha.And only trugh the freediving community
I dont think I will be diving thou,as there was clear irritation going on in my eye and eyelids, I guess that's what the apnea lenses fixex,by being bigger in diameter,that a standard sight correcting lens.
