Study Description

This study is for testing the efficacy and safety of distance-image screens intended usage for preventing myopia in children with reading after a 6-meter-distant-image device. It was a prospective study. The investigators would like to recruit 100 volunteers, aged 6 years 16 in Beijing.

All the volunteers will be complete examined their ocular parameters before using the distant-image screen in a random order for at least 2 hours daily for 12 month. The changes of ocular axial length and refractive error were both calculated before and after 12-month usage for paired t-test.
