Inclusion criteria
Inclusion criteria: 1. Age: 6 - 14 years old. Gender: Open to all. 2. The refractive status meets the following conditions: a) After cycloplegia, the computerized refraction test shows that the equivalent spherical refractive power of both eyes is within the range of -0.50D to -6.00D (including -0.50D and -6.00D); b) After cycloplegia, the computerized refraction test shows that the astigmatism of both eyes is <= 2.0D; c) After cycloplegia, the computerized refraction test shows that the refractive anisometropia of both eyes is less than 2.00D; 3. The intraocular pressure of both eyes is within normal range (greater than or equal to 10 mmHg, and less than or equal to 21 mmHg); 4. The best corrected distant vision of either eye is superior to or equal to 1.0. 5. Both eyes have no amblyopia or any other pathological changes in the eye; 6. The patient himself is fully aware of and voluntarily participates in this research, and has signed the informed consent form with his own and his parents/guardians' signatures.
