In most instances, astigmatism is present at birth. Sometimes, astigmatism develops after an eye injury, disease or surgery. Astigmatism isn't caused or made worse by reading in poor light, sitting too close to the television or squinting.

So, know you now more than my ophthalmologist?
FYI, there are several types of astigmatism, one of them is the one created by eyestrain and the continue use of LCD devices.
