Summary
This study is for testing the efficacy and safety of distance-image screens for preventing myopia in children for 12 month. Each subjects would be asked to paired test the ocular parameters between before and after 12-month distance-image screens.

- (4) Spherical Equivalence (SE) must have changed > 1.25 Diopter (D) in the recent 2 years;
- (5) Must be astigmatism <1.75 Diopter (D);
- (6) Must be anisometropia <1.75 Diopter(D).
Exclusion Criteria7
- (1) Strabismus disease;
- (2) Amblyopia disease;
- (3) Cataract disease;
- (4) Glaucoma disease;
- (5) Severe dry eye disease;
- (6) Cannot use distance-image screen for 12 month;
- (7) Other severe diseases that would effect the use of distance-image screen.
