Eyeglass lenses could be made of nearly any plastic or glass. For example, some glasses lens, such as my own, are made of a plastic called polycarbonate which is the material used to make bulletproof glass so my glasses are impact resistant. Other eyeglass lenses can be made from other plastics and glasses such as CR-39, Homopolyer and crown glass.

a convex lense
no, it isn't. Kevlar is the material in bulletproof vests
They use glass so it doesn't break easily or warp.

Gorilla glass is scratchproof, but I don't think it is bulletproof.
i think so
Alternating layers of glass and plastic resin. Truly bulletproof glass must be at least 4 to 6 inches thick! I've seen samples of such glass from WW2 bombers in museums. Modern bulletproof "glass" probably uses plexiglass plastic instead of real glass though. Note: a thick enough piece of ordinary glass is bulletproof by itself. Telescope mirrors (several feet thick) have been shot and although damaged the bullet did not pass through and after removing the bullet, drilling out the hole, and painting the inside of the hole black the telescope was returned to operation with no detectable loss of function.
Bulletproof glass
Bullet proof glass is made by laminating very strong layers of plastic film between layers of glass. This is done under very high pressure.
Aluminum, and bulletproof glass.
If the vehicle is aerodynamic, it would not.
There is currently no bulletproof laptop case,although there are bulletproof laptops used by the military.
no that's not funny the prez name was theo rosevlt
Pyrex glass is designed to withstand sudden & drastic TEMPERATURE changes. Most glass will shatter with sudden temperature changes. Pyrex is not bulletproof. Most transparent bulletproof material (glass) is composed of several layers of plastic & glass sandwiched together. The plastic holds the glass together, while the glass absorbs a bullet's impact.
