The thickening of the lens is called presbyopia. This condition occurs with age and results in difficulty focusing on close-up objects.
A lens that is thicker in the middle than at the edges is called a convex lens. It is a converging lens that causes light rays to converge at a focal point.
A concave lens is called a negative lens because it causes light rays passing through it to diverge, or spread out. This is in contrast to a convex lens, which converges light rays and is called a positive lens. The negative or positive designation refers to the effect the lens has on the light rays.
A convex lens is called a converging lens because it converges or brings parallel rays of light together at a focal point after passing through the lens. This results in the rays coming together and converging at a point on the other side of the lens.
The distance from a lens to the focal point is called the focal length.
A lens curved outward is called a convex lens. This type of lens is thicker at the center than at the edges and causes light rays passing through it to converge to a focal point.
The upper lens is called the ocular lens or the eyepiece.
The upper lens is called the ocular lens or the eyepiece.
Keratosis is the term for any condition that is a benign overgrowth and thickening of the epidermis.
when a beam of light is passed through the convex lens it converges the beam of ligth.hence convex lens is called a converging lens.

The process is called jellyfying or more generally thickening.
