How to prevent astigmatism in an early age?

[Joel]

My brother was just diagnosed with astigmatism and he need to wear glasses all the time. I don't want to have the same problem with him. How can I prevent astigmatism in an early age?

To prevent astigmatism in an early age, you should avoid eye strain. That is to say, you should not strain your eyes because too much eye strain will lead to refractive errors easily due to excessive eye use. Therefore using eyes in a proper way can help prevent astigmatism. Another thing you should notice is that it is better to read in in an appropriate lighting environment. Don't read in dim light, which can cause eye strain easily and lead to refractive errors. Rubbing eyes can also cause astigmatism. So you should avoid eye rubbing in order to prevent astigmatism.
