Wrong you both are... deep submersibles use a 10" "lens" as a view port

Sunglasses have lenses and yet do not alter the vision.

The pair of you should try learning as an option to spouting.

Right you are yet again, Joe. Thanks for backing me up
with your usual common sense and knowledge of boating
related issues.

I tried to tell that ignorant putz, JR, the same thing but he
is too smug and self-absorbed to listen to the facts.

the manufacturers and dealers call them lens.


They do that so they can charge suckers more.

It is not a lens. A lens is a transparent optical device used to
converge or diverge transmitted light and to form images.

Hope this helps
