Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Distance -image screen
Distance -image screen is a device to make image in the distance of 6-meters when reading and learning at near. The investigators will ask the subjects to use the distance - image screen for 12 month
distance-image screen
Distance-image screen is a screen make each image at distance of 6-meters to reduce the accommodation and convergence for eyes during the reading and learning with screens.
