Abstract: In order to improve quality control of eye guards and reduce testing period so as to guarantee safety of human eyes and promote export of products, luminous transmittance requirements and testing methods in domestic and foreign standards were analyzed. Then, based on broadband light source measurement method stipulated in the latest published international standard, a fast testing device was developed according to actual demand. Finally, it was calibrated by standard oculars. The results show that luminous transmittance requirements and testing methods vary significantly in standards of different countries. The newly developed testing device is accurate and fast, so it can be widely used as a standard testing instrument to measure luminous transmittance for eye guards.
