Do I need to wear glasses for 100 degrees of astigmatism?

Two days ago, the patient visited the ophthalmology department of a hospital, where the doctor diagnosed both astigmatism and myopia. The astigmatism measured 100 degrees. So, is corrective eyewear necessary for 100-degree astigmatism?

Is eyewear necessary for 100-degree astigmatism?

A 100-degree astigmatism typically does not require corrective lenses. Mild astigmatism is common, and symptoms often gradually improve with adjustments to visual habits. It is advisable to avoid prolonged use of electronic devices. Eye massage or warm compresses can promote ocular blood circulation and alleviate eye fatigue. Consuming eye-healthy foods—especially those rich in beta-carotene—is also beneficial. By modifying daily eye-use habits, mild astigmatism often decreases progressively.

The primary clinical concern regarding astigmatism is whether it causes reduced visual acuity or eye strain. If either occurs, corrective lenses are recommended for treatment. Astigmatism is a common clinical condition, primarily resulting from congenital asymmetry in corneal development, which causes light rays entering the eye to focus at multiple points rather than a single point. Generally, astigmatism under 100 degrees produces no significant clinical symptoms, as the eye can compensate through natural accommodation, maintaining good visual function. In fact, most people have this mild degree of astigmatism.

Patients should pay attention to their daily eye-use habits—avoid reading while lying down and minimize extended screen time. We hope this information is helpful to you.
