What symptom does 5 years old child astigmatism have?
1. Children's astigmatism is slightly heavy, regardless of distant objects, near objects, all feel blurred, children often have the habit of half closed eyelids narrowed into a gap, in order to make the object see more clearly.
2. Vision loss: astigmatism eyes far away from the retina focus line direction of the target color becomes pale, the edge of the virtual unclear, not easy to identify, vision loss, severe diplopia. In addition to physiological astigmatism, all kinds of astigmatism are easy to cause visual loss. The vision of hyperopic astigmatism is better than that of myopic astigmatism due to its regulating effect. When looking at the sight mark with oblique astigmatism, the sight mark is easy to deform.
3. Visual fatigue: astigmatism due to the different refractive power of each meridian, refraction of parallel light can not form a focus, but two focal lines, so the brain is easy to produce selective interpretation of the image. The reason is that astigmatism is easy to produce the scene in the direction of the focal line of the myopic omentum; In addition, in order to see the scene clearly, astigmatism eye should use adjustment as much as possible to reduce the size of the diffusion circle to improve the image quality; If high astigmatism is not corrected properly or does not wear glasses, it is easy to cause headache. Asthenopia and other symptoms, so astigmatism is easy to produce asthenopia.
