Eyesight+Correction+and+Lenses

__Eyesight Correction and Lenses__ - Allyson Porath

Normal eyes have light that bounces off of objects enter the lens of the eye and retina. The light is upside down inside the eye and send to the brain and creates an image.

Nearsightedness: able to see near To correct the too long to focus eyesight by using concave lenses. The lenses bend the light rays outward and makes the eyes "normal."

Farsightedness: able to see far Have to correct the too short of focus eyesight by using convex lenses. The convex lenses bend light inward before it reaches the lens of the eye.

All in all, both lenses bend the light to create the appropriate image. ([|www.ehow.com]).
