the cornea, the lens, and the retina. The cornea is a tough, transparent, dome-shaped tissue that covers the front of the eye (not to be confused with the white, opaque sclera). The cornea lies in front of the iris
focusing lens of the eye....
many say the pupil is the most imprtant part of the eye but it is actually the retina the part in the back of your eye.
The most imortant part of the eye that changes the direction of light is the LENS, though the cornea does do a little of the inital focusing.
The optic nerve
The lens does the lessor part, the cornea does the greater part.
The focusing lens of the camera
The eye is the part with out the most trouble on the eye wall is the worst
The lens. However, the human lens is flexible. Focusing is accomplished by tensing or relaxing the muscles surrounding the lens, changing its shape and therefore the focus. Camera lenses are inflexible, so focusing is accomplished by moving the lens closer or further from the film plane.The light rays first pass through the clear front part of the eye called the CORNEA. The light then passes through the PUPIL, which is an opening created by the IRIS or colored part of the eye. Next, the light passes through the LENS and finally arrives at the RETINA.So the part of the eye most oike the lens of a camera is the LENS. It's not the IRIS; that controls the size of the opening that the light comes though.
The cornea is responsible for focusing the light that enters the eye. It is the transparent portion of the eye that covers the front of the eye
The most intense part of a typhoon is the eye wall., just outside the eye.
The eye.
