The reason why the corrected visual acuity cannot reach 1.0 may be related to amblyopia, choosing unsuitable glasses, eye diseases, etc. Patients can wear suitable glasses, medication or surgical treatment, cover treatment to improve their visual acuity, and the specific treatment is related to the condition. 1. Amblyopia: Amblyopia means that the patient’s eyes have no organic lesions, but the patient’s visual acuity is lower than his/her peers. The patient can be treated with masking therapy to stimulate the development of the amblyopic eye and improve his/her visual acuity. 2. Selection of inappropriate glasses: If the patient chooses inappropriate glasses, it may also lead to the corrected visual acuity of less than 1.0, this time the patient needs to re-optometry, wear appropriate glasses, correct refractive error, improve vision. 3. Eye diseases: patients with uveitis, cataract, retinal detachment and other diseases can not be corrected to 1.0, patients need to target the causes of vision loss treatment. Uveitis patients can follow the doctor’s instructions to use atropine, tobramycin dexamethasone eye drops and other drugs to control inflammation and improve vision. Cataract and retinal detachment patients can have surgical treatment, such as cataract ultrasonic emulsification combined with IOL implantation, vitrectomy, etc., to improve vision. It is recommended that patients with vision loss should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
