Yea, people can be born with astigmatism. But take it easy, an English scientist once discovered that the amount of babies ranging from one month old to eight months old who have astigmatism account for 70 percent, as oppose to mere 8 percent in the adults. But strangely enough, when babies diagnosed with astigmatism are about 18 months old, their eyesight become normal automately. Causes of astigmatism may include watching TV frequently, sleeping with lights on, staring the computer screen and rubbing the eyes. If you are used to doing the first three things, you should make sure your baby is not around. Limit the time your baby spends in watching TV because babies are always easily attracted by the picture on TV. And do not let your baby rub her eyes. You can take your baby to do an eye examination when she is three.
