Age 8 to 15 years old (including 8 and 15 years old), gender is not limited; 2. post-ciliary muscle paralysis optometry with equivalent spherical lenses between -6.00 D and -0.50 D in both eyes, with astigmatism and refractive parametrization less than or equal to 1.50 D; 3. confirmed diagnosis of intermittent exotropia, with a hyperopic exotropia of 10? to 30? as measured by the trigonometric alternating masking test after masking the nondominant eye for 30 minutes; previous corrective surgery for strabismus and residual exotropia with a hyperopic exotropia of 10? to 30?; 4. In-office control scores of 1 to 3 for both hyperopia and hyperopia (measured 3 times by the same examiner within 30 minutes, with at least 2 scores meeting the requirements); 5. Best-corrected distance visual acuity of =0.8 in both eyes with a difference of <2 lines; 6. be able to cooperate in the continuous wearing of eyeglasses during waking hours; 7. patients and their guardians understand the content of the program and are able to attend regular follow-up appointments.
