Nearsightedness usually occurs when your eyeball is longer than normal or your cornea is curved too steeply. Instead of being focused precisely on your retina, light is focused in front of your retina, resulting in a blurry appearance for distant objects.
When a person is farsighted the light is focused?
When light focuses in front of the retina, near objects can be seen more clearly, while far objects appear blurry. Farsightedness, or hyperopia, is caused when the curvature of the cornea is too flat and hence causes light to focus behind the retina.
Where should light be focused in the eye?
Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain.
