The cornea, which is the transparent outer covering of the eye, acts as a convex lens by focusing light onto the retina.
The convex lens are the converging lens. The periphery of the convex lens is thinner & the center part is thicker. In other words, the convex lens are bulging at the center & thinner at the periphery.
In a convex lens, the middle is thicker than the outer rim. In a concave lens, the outside rim is thicker.

When the bottom half of a convex lens is painted black, the light rays passing through that part of the lens are blocked. This results in only the top half of the lens contributing to the formation of the image. The image that is formed will be incomplete, appearing distorted or cut off at the bottom.
The eyepiece lens of a compound microscope acts essentially a low power (x10 or so) magnifier of the real image created by the objective lens.

It depends whether it's a concave or convex lens. If it's a convex lens - the thickest part is at the centre. With a concave lens, the thickest part is around the edge.
In a convex lens, the middle is thicker than the outer rim. In a concave lens, the outside rim is thicker.
Any convex lens bulges out from each side. It is thicker at the centre of the lens and thinner at the edges. I am supposing that a spherical convex lens has convexity on both sides, but on one of those sides the glass is so curved that it has the shape of part of a sphere.

The photons are absorbed by electrons that they encounter, then re-radiated onward. If the convex lens is in a medium of lower refractive index, the light converges on its way through, and emerges still converging.
The light is delayed longer by the thicker part of the lens than by the thinner part of the lens. This results in the following:convex lens, light rays bend towards the axis of the lensconcave lens, light rays bend away from the axis of the lens
A parabolic mirror best focuses light onto a spot. Or a convex lens will do similar. In the eye, the lens towards the front of the eye focuses light onto the retina, where the light sensitive cells lie.
A flat piece of glass. Also, any lens where the shape of the convex part matches the shape of the concave part. An example would be a flat piece of glass bent over a sphere.

"Convex" is an adjective.
