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.
No. Lens is in the front of 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.
The part of the eye that is similar to a contact lens is the crystalline lens.
focusing lens of the eye....
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
The focus of the lens varies - depending on which part you look through. For example - the part at the bottom of the lens will be focused for reading or short distance, whereas the central part of the lens will be focused for longer distances.
