There is no harm in lowering the astigmatism slightly when the patient has mild astigmatism, but heavy astigmatism and too low a prescription can be detrimental to the eye.
Astigmatism is related to the curvature of the cornea and is a common type of refractive error. It is a common type of refractive error and is usually corrected and treated with eyeglasses. The difference between low astigmatism and good for the eyes is related to the value of the low prescription and the degree of the patient’s astigmatism.
1. If the astigmatism is less than 100 diopters, even if the prescription is lowered by 50 diopters or so, it usually does not have a significant impact on vision and visual quality.
2. If the astigmatism is greater than 100 diopters, lowering the astigmatism by more than 50 diopters will easily cause residual astigmatism, which may result in double vision and a decrease in corrected visual acuity. However, patients may also experience dizziness and discomfort with high astigmatism, and patients need to be fitted according to the actual situation.
It is recommended to go to the hospital for an optometry examination when astigmatism occurs, and fit the glasses according to the doctor’s recommendation.
