Generally speaking, if the temperature is above 200 degrees, it belongs to high astigmatism, and vision has been seriously affected. It is necessary to wear glasses, and the most important thing is to develop good eye habits.
The treatment of astigmatism mainly depends on the visual quality and the severity of visual fatigue. If it is regular astigmatism, it will not cause visual impairment, and there is no visual fatigue to treat. If you have visual fatigue, no matter what the degree of astigmatism is, even if the degree of astigmatism is very slight, you need mydriasis optometry and wear appropriate corrective glasses. In principle, all astigmatism degrees should be corrected, but if the astigmatism degree is too high to adapt, you can first wear low-degree correction glasses to adapt slowly, and then wear all eyes with corrected heights.

Treatment of astigmatism:
Including optical corrective therapy and surgical treatment. Wearing a cylindrical lens for optical correction is the main treatment for astigmatism.
1. According to the type and degree of astigmatism, different cylindrical lenses can be used to correct conventional astigmatism. Hyperopia astigmatism uses a convex cylindrical mirror, and myopia astigmatism uses a concave cylindrical mirror.
Mild astigmatism does not need to be corrected if there are no clinical symptoms, and corrective glasses should be worn if there are symptoms of decreased vision or visual fatigue or visual interference.
Children, especially preschool children, must fully correct astigmatism and prevent amblyopia.
Optometry should be done before wearing, and mydriasis optometry should be done for teenagers and children. It can also be combined with the measurement of corneal curvature meter to understand the true nature and degree of astigmatism, and then combined with subjective audition to determine the prescription of glasses.
High astigmatism can be corrected with contact lenses if it can't adapt to frame glasses.
2. Irregular astigmatism is not easy to be corrected with lenses, but can be corrected with contact lenses.
3. Surgery is suitable for congenital or acquired high astigmatism caused by eye surgery such as cataract or corneal transplantation, such as excimer laser refractive corneal surgery, laser keratoplasty and keratotomy. 、
