Adults with 200 degrees of refractive error may not wear glasses if it does not affect their normal life. For example, if it is not convenient for the patient to wear glasses when playing sports, he/she may not wear glasses for a while. Adults with 200-degree refractive error are mild refractive error, although it will affect the vision, but if the patient’s life and work in the fine visual function requirements are not high, temporarily without glasses will not jeopardize the health of the eyes, especially in the patient to play sports, such as basketball, swimming without glasses, it is not a problem at all. However, if the patient has a high demand for fine visual function, he or she should still wear eyeglasses to correct the problem. Patients can visit the ophthalmology department of a hospital and speak to the doctor about their eye needs, and then the doctor will assist in making a judgment.
