After World War II, scientists began searching for optical instruments that used alternatives to glass lenses, such as radio waves
Plastic materials, such as polycarbonate and CR-39, have replaced glass in some lens designs due to being lighter, more impact-resistant, and more affordable. These materials can still provide excellent optical quality for eyeglass lenses.
Yes. The lense of a magnifying glass is a convex lense. Convex lenses bulge outwards from the center of the lense on both sides.

Yes, a piece of glass or plastic rod can be used as a cylindrical lense. If more precision or a nonstandard diameter is needed then a custom made cylindrical lense can be made of either glass or plastic to order.
It depends on if you have a dipstick or a glass lense. My Grizzly has a glass lense at the base of the engine on the left hand side. I fill it about 3 quaters of the way and i use about 3 quarts of oil.
Compared to a uniform thickness lense, concave is where the lense is thinner towards the center of the focal point of the lense than at the thicker edge; convex is much like a magnifying glass where the lense is thicker near the center focal point than at the thinner edges.
lenses bend light by having the light pass through the glass(or whatever material) of the lense in which the light will slow down. As the light enters the glass the very first part of the ray will slow down alowing other parts to catch up. This makes the light bend towards the normal (perpendicular to side of glass). As the light leaves the glass the oposite occurs. The light that leaves the glass goes faster leaving other parts behind and bending it away form the normal. How much the light bends depends on the shape of the lense the material of the lense and the angle that the light comes in at.
There are a few ways to design a glass window. You should start the design process with a blue print.
no its a rare glass
Depends on the people who make them. Some go bad after a short time. Others are much longer. Also you spelled the word "lense" wrong. It should be "lens"
in a magnifying glass the glass is special type of glass. glasses lense are made of lint glass. magnifying glass is made of a thick glass. telescopes and magnifying glasses both use thicker glass than the usual. hope i helped you.
