convex
A convex lens curves outwards from the middle. This type of lens converges light rays towards a focal point, commonly used in magnifying glasses and cameras.
A biconvex lens is thinner at the edges and thicker in the center. This type of lens causes incoming light rays to converge, making it useful in applications such as magnifying glasses and camera lenses.
Bifocals.
Safety glasses are designed to provide clear vision while protecting your eyes. They should not interfere with your vision on a forklift if they are properly fitted and have a clean lens. It is important to wear safety glasses to prevent potential eye injuries in the workplace.
A lens in glasses refracts light, bending it in a way that helps to focus the light onto the retina of the eye. This can correct vision problems such as nearsightedness, farsightedness, or astigmatism by changing how the light is focused on the retina.

No, you cannot change the bifocal prescription on glasses without changing the lens. The lens is what is prescribed by your eye doctor. The frame, however, can be changed.

Glasses are a plural form for glass (a drinking glass, or a lens). To indicate the plural of glasses (eyewear, a pair of eyeglasses), you would have to use the description "pairs of glasses."
do you mean glasses to wear or glasses to drink from? With glasses to wear, the lens falls out. they use a special kind of glue and some wire to stick it back into place, and then screw it in. With drinking glasses, they are VERY hard to repair, but I guess glue and a lot of time and patience would do the trick
