It is a prospective clinical control study on red light control myopia with specail design spectacles for 75 children in 3 groups. Each group has 25 myopic children. Study Groups with two different powers of 0.6 mW and 1.2 mW at wavelength of 650nm are randomized to be allocated into the 3 groups. The control group is to wear the same brand and design spectalces as those two study groups. In addition, the progression of myopia is usually accompanied by the changes in a variety of ocular parameters, such as refractive error, reduced submacular choroidal thickness, and prolonged length of the ocular axis length. All groups will be wearing a special lens named by Stellest with high aspherical lens design.
