Cornea<\/strong> : It is a thin membrane through which light enters. It forms the transparent bulge on the front of eyeball. Most of the refraction occurs at the outer surface of the cornea.<\/p>\n<p>2. <strong>Eyeball <\/strong>:it is a convex lens,\u00a0approximately spherical in shape, with a diameter of about 2.3 cm. It can alter its curvature with help of ciliary muscles.<\/p>\n<p>3. <strong>Iris :<\/strong>It is a dark muscular diaphragm that controls the size of pupil.It is behind the cornea.it helps in accommodation of light by changing the size of the pupil.<\/p>\n<p>4. <strong>Pupil <\/strong>:It regulates and control the amount of light entering the eye. It is the black opening between aqueous humour&amp; lens.BLack in colour. Light entering cannot exit.<\/p>\n<p>5. <strong>Crystalline eye lens<\/strong> :Provides the focused real &amp; inverted image of the object on the retina. It is composed of a fibrous, jelly like material.<br \/>\nThis is convex lens that converges light at retina.<\/p>\n<p>6. <strong>Ciliary muscles<\/strong> :It helps to change the curvature of eye lens and hence changes its focal length so that we can see the object clearly placed at different positions.<\/p>\n<p>7. <strong>Retina<\/strong> : Thin membrane with large no. of light sensitive cells.<br \/>\nThere are two types of photoreceptors in the human retina, rods and cones.<br \/>\nRods are responsible for vision at low light levels . They do not mediate color vision.<br \/>\nCones are active at higher light levels , are capable of color vision.<br \/>\nWhen image is formed at retina, light sensitive cells gets activated and generate electrical signal. These signals are sent to brain via optic nerve. Brain analyse these signals after which we perceive object as they are.<\/p>\n<p>8. The\u00a0<em>vitreous body<\/em>\u00a0is the clear gel that fills the space between the lens and the retina of the eyeball of humans and other vertebrate<\/p>\n<p>9.
