It's a pizza crust. The middle is thick and doughy, while the edges are thin and crispy.
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.
It's a pizza crust. The middle is thick and doughy, while the edges are thin and crispy.
Concave. The opposite- thick in middle, thin at edges- is convex.
No, that's concave Convex is thin at the edges and thick in the middle.

The ruler is thin by the edges so that the markings can be easily compared with whatever is being measured. It is thick in the centre so that it does not snap too easily.
Lenses with thick centers and thin edges are called convex lenses. They converge light rays towards a focal point, which allows them to focus light and produce real images.
A thin atmosphere is thin and a thick atmosphere is thick
concave lense is a piece of smooth glass that is thick from the edges and thin from centre and is used to diverge light rays.
That's commonly called a border. Borders can be as thin as one pixel, or as thick as you want !
