Genetics: Myopia, or nearsightedness, means one can see near objects but distance vision is blurry. Myopia is usually genetic and there is no known reason. It could be caused by a longer than normal eye or a steeper cornea.

Unknown: Myopia is common and seems to be increasing. There are many theories such as sustained reading, computer use and a bunch of theories related to neural functioning and various dietary issues. None so far have been consistently proven so we do not yet know the cause. It is a hot area of research and hopefully the answer will surface.
