Normalized spectral settings in light- and myopia-related experimental studies

There are more and more studies investigating the influence of spectral difference on myopia, but the settings of light sources are different in each study.As a physical quantity, light can be measured radiometrically, mainly to detect the energy properties of light.As a psychological and physical quantity, the light should be measured photometrically to detect the degree of light perception of the organism.Different optical measuring tools measure based on the response curve of the photoelectric conversion device.The essence of the light source spectrum setting in the experiment is to control the sensitivity of organisms to light.Therefore, special attention should be paid to the influence of light source setting differences when interpreting similar experimental results.When setting the light in animal experiments, it is necessary to consider the differences in the absorption curve of the animal’s photosensitive pigment and the curve of the animal’s spectral light efficiency.It is also suggested that a radiometer should be used to unify the photon flux density consistent among different groups based on 200-300 lx light intensity.In this paper, the normalization of spectral settings in experiments related to light and myopia was reviewed.
