How does the eye have glitter to do

summary

Many people will have astigmatism when they are short-sighted, but many people don't know much about astigmatism. Today I'd like to share with you how to do with astigmatism.

How does the eye have glitter to do

First of all, astigmatism refers to the refraction of parallel light through the eye refractive system, which does not gather into a single point, but scattered many light images, so it is called astigmatism.  

Secondly, the so-called astigmatism refers to regular astigmatism. Most of this kind of astigmatism is congenital, mainly caused by abnormal corneal radian. In normal infants, the prevalence of this kind of astigmatism is quite high, which may be related to the pressure of upper eyelid. Sometimes it is also called physiological astigmatism, and the degree is very slight.

Finally, if only mild astigmatism, then there is no need for treatment, or correction, but if the work is more precise, or you need to read some small text, you can consider wearing astigmatism glasses.

matters needing attention

If you have astigmatism, don't watch TV or read for a long time. Generally, you need to relax your eyes for 5 minutes every half an hour. When you watch TV, you should keep a certain distance from the TV picture.
