Optical Spectrum, Retinal Focus, Metabolic, and Ecological Factors Influencing Myopia in School Age Children

The global prevalence of myopia in children under 19 years isprojected to be 324 million by year 2025. The optical stimuli atthe retina that specify focus (e.g. comparison of luminancecontrast between cone types) to control accommodation havealso been demonstrated to drive eye growth mechanisms,integrated, however, over a sustained near focusing interval,that is disrupted by brief periods of myopic defocus. Reviewson the role of illumination (spectrum, intensity and temporalfrequency), circadian rhythm disruption, and light-induced changes in sex hormones, have been published in recent years.
