Document Summary
The lens causes vision (cataracts obstruct vision) Theory of vision (middle ages: classical knowledge of greece and rome in arab world, size of pupil affected by light levels. Intromission (light enters eyes: looks black because of retinal pigment epithelium which acts like a sort of dark room. Cornea: clear tissue at the front of the eye. Iris: sphincter that controls the size of the pupil. Lens: focuses the light to the back of the retina. Retina: photosensory membrane lining the eye: 2 parts: Fovea: high resolution vision the eye is) Light comes into the cornea and pupil: methods of regulating light: Exclusively made of densely-packed cones: optic disk: where the axons bundle up and leave the eye (this is where the blind spot of. Prevents optical aberration: better resolution by using centre of the lens. Decrease iris size increases depth of field (better for focusing on different. Focusing the light: layers at a time: depends on cornea and lens.
