"Joe" wrote in message oups.com... Wrong again Mooron. Subs have viewing ports not lenses unless the are concave or convex and reshape light transmitted thru them. . Only reason sunglasses have Lenses is because they are a rip off of the proper name of perscription lenses used in standard eye glasses that predate sunglasses. The proper terms is sunglasses or filters, not sunlenses. You should try learning before spouting off. Quit being a Pane in the ass.... |
If I lost 30 lbs. I'd be emaciated...Mr Sails would not appreciate that at
all... "Capt. Neal®" wrote in message ... "katysails" wrote in message ... Glass is a heck of a lot heavier than Lexan...which makes a difference for anyone that has a performance boat...I'd stick with Lexan... If you were really worried about performance of your French Failure, you would go on a diet and lose about thirty pounds. Mr. Sails would appreciate THAT a lot more than a hatch that weighed two pounds less. CN |

"Joe" wrote in message It is not a lens. A lens is a transparent optical device used to converge or diverge transmitted light and to form images. Really? And what exactly does a plano lens do? Max |
"Capt. Mooron" wrote in message Sunglasses have lenses and yet do not alter the vision. Actually they do. Max |
"Joe" wrote in message Wrong again Mooron. Subs have viewing ports not lenses unless the are concave or convex and reshape light transmitted thru them. . Um, wrong again. Only reason sunglasses have Lenses is because they are a rip off of the proper name of perscription lenses used in standard eye glasses that predate sunglasses. The proper terms is sunglasses or filters, not sunlenses. And again. You should try learning before spouting off. So should you, Joe. Lenses do a wide variety of things, including causing light to diverge or converge, as you've implied. They occasionally do nothing at all, such as with plano lenses. They can act as light filters, as with sunglass lenses. They can neither diverge nor converge light, but bend light, aka prismatic lenses. They can affect color vision, aka colored filter lenses. They can simply reduce light level without coloration, aka neutral density lenses. And the list goes on, and they are ALL properly called lenses. So are those glass or resin plano "windows" in portholes, etc. It's a traditional term in those cases. Max |

Plano lenses, for example, used in spectacles are curved both front and back, and allow light to pass through them without being refracted. Should I continue? Max |
Don't bother...it's like providing sex education to a eunuch...
