The expressions relate to the shape of the surfaces of the lens. Concave means that the surface is like the inside of a sphere, convex means that it looks like the outside surface of a sphere. A lens has two surfaces. Most often the spectacle lens are bent away from the eye: the nearer surface is concave and the outside surface is convex.

∙ 11y agoA concave lens is a diverging lens,if rays of light are focused on it (parallel to principal axis),practically it will be appearing to meet at the focus, but the real light rays, will go on other direction(diverge).It is thinner in the middle than at the edges.
A convex lens is a converging lens,if light is focused on it(parallel to the principal axis),practically it will converge all the light rays to focus.It is thicker in the middle than at the edges.
I think u got it mixed up.

How can you remember the difference between convex and concave lenses?
A concave surface curves inward. Cave-in
How are concave and convex lenses different?
Convex bulges outward (thicker in the center than the edge)Concave bulges inward (thinner in the center than the edge)Convex lenses magnify when you look through then, concave lenses make things look smaller.You can focus a distant object to a point with a convex lens (the image will be upside down).
What is the difference between a concave and convex lens?
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
Do cameras have concave or convex lenses?
yes
Difference between convex and concave lens?
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
How can you remember the difference between convex and concave lenses?

How are convex lenses and concave lenses the same?
They are not the same. Convex lens bulge outward, and concave lenses go in ward. Convex lenses focus light, and concave lenses spread light out.
What is the main difference between how convex and concave lenses affect light?
Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.
Are objective lenses concave or convex?
Objective lenses are convex lenses.
What are two type of lenses?
convex and concave
What are the differences between concave and convex lenses?
Concave lenses curve inwardly.Convex lenses curve outwardly.* See related links.
Do binoculors have concave or convex lenses?

Do microscopes use concave or convex lenses?
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
