Clinical Trial Summary

The study explores the suppression of myopia via violet light.

Description:

The study uses violet light-emitting lamps as the variable and regular, white light lamps as the control in assessing whether violet light, especially during over periods of dawn and dusk could help suppress the progression of myopia in developing children.
