Generally because people who are short sighted (vision - not in thought) will reproduce just like people who are not short sighted. A trait is only lost from a species if it inhibits the reproductive success of the carrier. But in the humans' social environment, people who are short sighted continue to have offspring who are short sighted as well. In other words, a standard for marriage (and other unions) is not determined by perfect eyesight.The only way for the gene for short sightedness to be eliminated would be for those who are short sighted to be eliminated from the population.

convex lenses are for short sighted people.
