Flexing like the lens of a mad eye refers to someone who is demonstrating extreme levels of intensity, focus, or alertness, similar to how the lens of a mad eye constantly shifts and looks around rapidly. It implies a heightened state of awareness or readiness.
The cornea or lens of the eye.
It is covered by a cellophane-like capsule.
The term for an eye in which the natural lens has been replaced with an intraocular lens is "pseudophakic eye."
In a camera the following parts could be considered equivalent to the parts of a human eye:Optical diaphragm = IrisAperture in optical diaphragm = PupilOuter lens element / lens glass = CorneaInner lens element = Eye lensCCD Sensor (in a digital camera) = RetinaThis is a huge simplification of a very complex topic. Please see the related links for more information.
The vitreous humor is the jelly-like clear substance that is between the lens and retina in the eye.
I have a prosthetic eye. It's like a contact lens, and it goes in similar to a contact lens
what do you mean
Because the lens is really liquidy and jelly-like, it is the only part of the eye that shakes like jello!
Short sighted people are not helped by lenses or anything else. Except the consequences of their short sightedness. I think you mean near sighted people. The eye is a lens and focal point system. The focal length of the eye can be manipulated by flexing muscles in the eye socket to change the distance between the lens and the back of the eyeball. A near sighted, or even a far sighted, person has an eyeball that is too long or too short for the lens, and therefore the image produced by the eye's lens is focused either in front of or behind the back of the eye. A lens, either in a pair of glasses or a contact lens, can assist the eye by effectively pre-focusing the image that enters the lens of the eye to a sharpness that can be accommodated by the focal length of the malformed eyeball, focusing the image sharply on the back of the eyeball. - wjs1632 -
The iris acts like the aperture of a camera lens.
The cornea or lens of the eye.
The opposite of a fish eye lens is a telephoto lens.
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.

Yes it is a convex lens just like the one in your eye! A convex lens goes outwards but a concave lens goes inwards (like a cave). Simple! :-) xoxo
No he does not. His right eye is like that because of a contact lens as part of his gimmick. (:
The cornea, which is the transparent outer covering of the eye, acts as a convex lens by focusing light onto the retina.
