What reason is eye clear astigmatism?

summary

Astigmatism is due to the different thickness of the cornea inside the eye, which leads to different refraction angles of light, so that people can't see the same angle, the object refracted will be blurred in the eye. The cornea of the eye is like a magnifying glass. If the edge of the magnifying glass is uneven, thin and thick, the object you see cannot be magnified clearly. What reason is eye clear astigmatism? Now let me tell you something.

What reason is eye clear astigmatism?

The causes of astigmatism are congenital and acquired. Some congenital, may be due to genetic, the development of the cornea gene is not correct, can not develop the cornea well. The day after tomorrow, there are many possibilities to cause astigmatism. Such as postnatal injury, incorrect eye use, etc.

In our daily life, sometimes we don't pay attention to using our eyes, such as lying reading, playing mobile games for a long time, staring at the computer for a long time, looking at the flashing light in the dark, will damage our cornea. As we grow up, the elasticity of the film becomes lower. When we look in one direction, the cornea can adjust its thickness so that we can see the object clearly. When we stare in one direction for a long time, the thickness of the cornea is formed. When we change the direction, because the elasticity of the cornea becomes lower, it cannot return to the original thickness, We can't see the object clearly, which forms our visual astigmatism.

There are also some postnatal reasons may be due to not pay attention to bump, improper use of eyes, resulting in corneal scratch cracks. When we use the eye again, the cornea can't be used well, and we can't see clearly. It's like a piece of magnifying glass is scratched, dropped and worn. If you use this kind of broken magnifying glass, you can't clearly see what is magnified, just like our astigmatism.

matters needing attention

We can't avoid congenital astigmatism, but in our daily life, we can use our eyes healthily to ensure that our cornea will not be damaged. We can prevent astigmatism fundamentally without staring at an object at the same angle for a long time, without rubbing our eyes or looking at the flashing lights, so that we can have a pair of healthy eyes.
