Near sightedness is a condition whereby the eyeball is too long or cornea has excess curvature such that light entering the eye is focused in front of the retina rather on the retina itself.
The exact cause of nearsightedness is unknown but there are two factors that may be responsible for its development.
1. Visual stress
2. Heredity
Individuals who spend considerable time reading or working at a computer or engage in other types of intense close visual work may develop nearsightedness.
There is credible evidence that many people inherit nearsightedness or are at least predisposed to the condition, especially if both parents suffer from the condition.
Far sightedness (hyperopia) is a condition where the eye is shorter than normal, the cornea is not curved quite enough or the lens sits further back in the eye than is normal.
This condition can be inherited especially if both parents suffer from it.
The other cause is through diseases like diabetes or glaucoma.
This varies from person to person. There is a point in time at which hormones in a persons body begin to loose their effective functions, a period I have heard reffered to as adult puberty. In women this is marked by menopause. While you can still theoretically maintain a healthy body at this time, it becomes increasingly difficult. Maintaining a healthy diet and constant exercise are essential to achieving this. A doctor won't tell you much more than this.
