Purpose: We have suggested the way to improve performance of blue-light blocking lens through the analysis of blue light emitted from LED light sources
and compared the performance of blue-light blocking lenses commercially distributed in domestic market.
Methods: A total of 17 blue-light blocking lenses and a total of 41 LED light sources were used in the study. The light spectral distributions of LED light sources were measured using illuminance spectrometer. The blue-light distribution
of each LED light source was calculated from the product of blue-light hazard function and the light spectral distribution of LED light source. The peak wavelength and the full width of half maximum of the blue-light distribution of
each LED light source were calculated using the Gaussian curve fitting. Results: The blue-light distributions of all light sources could be well fitted to the Gaussian curve. The hazard induced by the blue light of LED light sources was found to be averagely the greatest at the wavelength of 450 nm. However, the reflectance of domestic and foreign blue-light blocking lenses was found to be averagely the greatest at 431 nm and 448 nm, respectively.
Conclusions: It is necessary to design the blue-light blocking using Gauss fit curve with the peak wavelength of 450 nm and the full width of half maximum of 27 nm in order to block the blue light emitted from LED light sources optimally. In this respect, it may be better to change design of the blue-light blocking for some of blue-light blocking lenes
