Description
Summary:Although a variety of experiments on light exposure stress to animals significantly affect the retina and circulation system, it is still unknown the relationship between the different extent of harmful effect on organism and light with different wavelengths and power. This study is aimed to investigate the changes to microblood vessel and the variations in serum absorption spectrum. LED light of different wavelength and power were used. The results show that power has a relatively larger impact on physiological indexes than wavelength. The extents of these variations are relatively different according to the regression equations. All of these stimulations cause damage to mice physiological conditions, producing some extent of light pollution. The research findings supply the guideline for the effective prevention of the harmful effect on organism by light pollution from the view of science of optical life science.
