Study on the Biohazard of Incoherent Blue Light from Medical Device on the Retina
摘要
Abstract
Objective To determine the impact of different testing conditions on the evaluation of blue light biohazard on the retina and product classification. Methods In combination with the classification standard of light radiation hazard, the biomechanism of retinal bluelight hazard was analyzed. Blue light hazard on the retina from UV light and LED light was tested under different conditions separately (including distance, aperture stop, field stop). Results Blue light containing UV component generated more hazard on aphakic eyes (infants less than 2 years old) than regular eyes, which would probably change classification results, while lower UV proportion didn't show significant impact. The testing device didn't change the luminance of the light source. The difference of testing condition only changed the selected range of radiant angle and area with different results. Conclusion The difference of testing conditions has impact on radiant exposure, but in general, it doesn't change classification results. To assure the accuracy of radiant exposure measurement, appropriate experimental condition should be selected based on the actual circumstance of light sources following the most unfavorable rule.关键词
