The prescription is 25 degrees higher than the optometric prescription, which may affect the patient’s vision and easily cause visual fatigue. Generally speaking, if a patient suffers from myopia, astigmatism and other refractive errors, the patient should go to the ophthalmology department of a regular hospital for an optometric examination, and the doctor will eventually issue a prescription for glasses according to the results of the optometric examination, and then test and fit the glasses according to the prescription. If the prescription is 25 degrees higher than the prescription, the patient will easily suffer from visual fatigue due to wearing inappropriate glasses. However, due to the relatively small error of 25 degrees, the patient’s corrected visual acuity is not necessarily abnormal, but generally can not see for a long time, and is prone to eye soreness, dizziness and other uncomfortable symptoms. It is recommended that patients with refractive errors seek timely medical attention to assess their condition and follow the doctor’s instructions for correction.
