Astigmatism is a kind of ametropia. In daily life is very common, many people will have the phenomenon of double vision, blurred vision, visual fatigue, squint and so on, but because the symptoms are not serious, did not pay attention to. In fact, astigmatism is not terrible, most people's eyes have varying degrees of astigmatism. Astigmatism in children? Let's talk about it.

Astigmatism in children?

1. Blurred vision: blurred vision is closely related to the degree and manner of astigmatism. Slight astigmatism is usually hard to detect, but when you look at things at a certain distance, your eyes will be swollen, tired, blurred, and even have a headache. Serious astigmatism, will appear to see the object can't see clearly, sometimes appear distorted phenomenon, can't distinguish between near and far. More serious astigmatism will appear double shadow phenomenon.

2. Asthenopia: the blurred image on the retina needs constant fine adjustment, and the vision is distorted, so astigmatism, especially hyperopia astigmatism, is prone to asthenopia.

3. In order to see more clearly, people who have highly asymmetric astigmatism in abnormal head position and eye position often take tilted head position, resulting in strabismus, and astigmatism can be recovered after correction. People with high astigmatism often squint when they look at distant objects to achieve pinhole and fissure effect, so as to improve their vision.

In addition, there is the crack slice inspection method. The slit sheet makes the eye only accept the light in the same direction as the slit and block the scattered light in other directions. When the slit film is placed in the normal eye, and the slit is placed in any direction, the visual acuity does not change. For astigmatism eyes, the visual acuity is better only when the slit is consistent with the astigmatism axis, and the visual acuity can be corrected to the best when the slit is consistent with the astigmatism axis or the vertical direction of the astigmatism axis.
