A clear thing behind the Iris but befor the Retina
an eye piece lens
I have a prosthetic eye. It's like a contact lens, and it goes in similar to a contact lens
the lens is changed
Because the lens is really liquidy and jelly-like, it is the only part of the eye that shakes like jello!
The iris acts like the aperture of a camera lens.
The cornea or lens of the eye.
It's called an "OCULAR" according to a microscope supplier site.
the lenses make objects look smaller than what they are so that people know what they look like.
how does light effect your eye? In a compound light microscope? The light passes through three lenses between the light source and your eye. The first lens is the condenser lens.. The second lens is the objective lens. The third and final lens is the Eyepiece, also known as, the ocular lens. This is the lens you look through. These are the lenses that light must pass through to get from the light source to your eye.
Actually, the lens on your eye moves just like the lens of a camera to focus light. People who are nearsighted or farsighted have trouble focusing on objects that are very close or very far away. Since the lens on your eye isn't as big as the lens on a camera, it's just harder to observe it moving.
It is covered by a cellophane-like capsule.
The muscles around the lens of your eye push and pull it thicker and thinner to focus your eye on an object depending on the distance from your eye to the object. The focal length of a fat lens is shorter than the focal length of a thin lens (the light rays are bent more sharply) When you focus binoculars, you are adjusting their focal length
