Does the targeted photon fill light instrument belong to Class II or Class III?

Three categories. Three types of medical devices refer to medical machinery used to diagnose, treat, monitor and alleviate serious diseases, and the second type refers to medical machinery whose safety and effectiveness should be controlled. Targeted photon light-filling instrument adopts biological photon technology, and supplements relevant beneficial spectrum and light nutrition for eyes according to the composition ratio of nine light-dependent opsins in human vision-related cell chromosomes, in order to alleviate serious diseases and meet the three standards, so targeted photon light-filling instrument belongs to the third category.
