Does binocular astigmatism need glasses for 50 degrees?

If the astigmatism is below 50 degrees, it is generally not necessary to wear glasses. However, because the degree of astigmatism is relatively small, it is impossible to judge whether it is necessary to wear glasses simply by the degree. It depends on how much visual acuity the patient can achieve with the naked eye and whether there are any uncomfortable symptoms.

Pay attention to eye rest at ordinary times, avoid fatigue and staying up late, try to play mobile phones less, surf the Internet less, do more outdoor activities, read books and study in a correct posture, and get enough light.

Extended data:

The treatment of astigmatism includes optical correction and surgical treatment. Wearing a cylindrical lens for optical correction is the main treatment for astigmatism.

1. Regular astigmatism

Different cylindrical lenses can be used to correct astigmatism according to the type and degree. 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

It is difficult to correct with lenses, but it can be corrected with contact lenses.

It is suitable for cataract surgery or corneal transplantation surgery, such as excimer laser refractive corneal surgery, laser keratoplasty, keratotomy and other congenital or acquired high astigmatism.
