Abstract
Myopia is a clinically significant and growing problem around the world. A major cause is the increasing time spent indoors by children, for example, playing video games, studying, and watching television. Exposure to sufficient overall light levels is known to be protective, and prevents the onset and also delays the progression of myopia. Embodiments include a computerized myopia progression retarding (“MPR”) system that includes a light source configured to provide illumination and an illumination sensor configured to sense ambient light. The MPR system also includes a processor configured to dynamically adjust the illumination in terms of either wavelength bands or luminance provided by the light source to solicit a target wavelength band or luminance for retarding myopia progression of a user.
