A convex lens.
oncave
A lens that is thin in the middle and thick at the edges is convex. This shape causes light rays passing through the lens to converge and focus at a point, making it a converging lens.
A converging lens or a convex lens is thick in the middle and thin at the edges. It causes light rays to converge at a focal point, which makes it useful for focusing light in optical systems like cameras and telescopes.
Actually, a lens that is thinner in the middle than the edges is a convex lens, not a concave lens. Concave lenses are thicker in the middle and thinner at the edges, while convex lenses bulge out in the middle.
A spoon that you have put some food into is a concave shape. It is a cavity. A concave lens is such that it is thicker at the edges than in the middle. Convex is the bottom of the spoon. A convex lens is thicker in the centre than around the edges.

Concave. The opposite- thick in middle, thin at edges- is convex.

a concave lens is thin in the middle, but thick on the sides. It does this: it makes what you look at bigger because it spreads out light

Two basic kinds of lenses are converging lenses, which focus light rays to a point, and diverging lenses, which spread out light rays. Converging lenses are thick in the center and thin at the edges, while diverging lenses are thin in the center and thick at the edges.
A thick lens has varying thickness across its surface, which affects how light is refracted. A thin lens is assumed to have a uniform thickness, simplifying calculations in optics. Thick lenses can produce more complex optical effects compared to thin lenses.
A convex lens.
Yes, this is a concave lens. It is also called a diverging lens because it causes light rays to spread out.
A thick convex lens has a larger thickness and can bend light rays more than a thin convex lens. This results in a shorter focal length and stronger focusing ability for a thick convex lens compared to a thin convex lens.
