The object distance of a convex lens is measured from the optical center to the object, while for a concave lens, it is measured from the optical center to the object along the path of light. In general, the object distance for a convex lens is positive, while for a concave lens, it is negative since the object distances are measured on the opposite sides of the lens.
A convex lens converges light rays to a focal point, used to correct hyperopia (farsightedness) or create magnification in optical devices. A concave lens diverges light rays, used to correct myopia (nearsightedness) or reduce image size in optical systems.
A concave lens has a curved surface that curves inward on both sides, causing light rays to diverge after passing through. In contrast, a plano-concave lens has one flat side and one curved concave side, which also causes light to diverge but with less optical power compared to a fully concave lens.
A concave lens is a lens that is thinner at the center than at the edges. It causes light rays to spread out, diverging as they pass through the lens. A prism is a transparent optical element with flat, polished surfaces that can refract, reflect, or disperse light.
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .

It is not necessary that a thinner convex lens have less optical power or a thicker lens has more optical power

A lens with an optical axis is symmetrically designed, meaning that the center of the lens coincides with the optical axis. This axis passes through the center of curvature, allowing light to pass through without significant deviation. Lenses that are not symmetrical may not have a distinct optical axis.
The focal point F and focal length f of a positive (convex) lens, a negative (concave) lens, a concave mirror, and a convex mirror. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
When concave and convex surfaces come together, they form a lens. The interaction of these two surfaces causes light to either converge (convex lens) or diverge (concave lens), which can be used in various optical devices like cameras, telescopes, and eyeglasses to focus or correct vision.
The curvature of the radius of a lens affects its focal length and optical power. A lens with a shorter radius of curvature will have a shorter focal length and higher optical power, while a lens with a larger radius of curvature will have a longer focal length and lower optical power.
