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.

Alice could:
- Avoid touching a bare wire that may be conducting a current.
- Avoid overloading power strips and other receptacles with multiple plugs. Using only two plugs per outlet lessens the risk of shock and fire
- Utilize three-prong plugs whenever possible. The third prong, which grounds the electrical current, should never be removed.
- Never assume that someone else turned off the power source. Always check for herself!
