Lens is part of contact.
The Shutter.
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 part of the eye that is similar to a contact lens is the crystalline lens.
focusing lens of the eye....
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 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.
