Farsightedness is the result of the eyeball being too short, and/or the lens of the eye not being flexible enough, for proper focus to . The main parts of the human eye are the cornea, iris, pupil, aqueous humor, lens, vitreous humor, retina, and optic nerve. Macula: The macula is the small, sensitive area of the retina that gives central vision. Together, the cornea and the lens behind it focus light onto a layer of sensory cells at the back of the eye.

The cornea is the transparent covering over the eye. It controls the amount of light that enters the eye. The fovea . Rods help you detect movement while cones help you see color. The lens of the eye is the key component that allows sight. Eyes detect light and convert it into electro-chemical impulses in neurons. Eyes are animal organs that are specialized for sight. Ok, so how does our eye turn the light into neural impulses so that our brain can understand. The cornea is the transparent covering over the eye. the light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information. The eye is the major sensory organ involved in vision (). Light waves are transmitted across the cornea and enter the eye through the pupil. Both of these receptors transfer light into electrical impulses so that your brain can interpret them. thansen3. Lens The lens is located in the eye. lens noun lens noun A convex shape bounded by two circular arcs, joined at their endpoints, the corresponding concave shape being a lune.

The crystalline lens, a clear disk behind the iris, is flexible and changes shape to help you see objects at varying distances. The lens is attached to muscles that can change its shape to aid in focusing light that is reflected from near or far objects. Eyes are organs of the visual system. The light focused by the lens will be transmitted onto the retina. The cornea is the transparent covering over the eye. The lens is constantly changing shape depending on whether we are looking at objects close to us or far away. The retina is located in the back of the eye, and is connected to the optic nerves that will transmit the images the eye sees to the brain so they can be interpreted. Fear may follow.
