Traditional life contact with a variety of lighting sources, such as home lighting, street lamps, flashlights, etc., in modern daily life, LED, TV, computer, cell phone screen, camera flash, traffic lights, electronic police camera flash, bar dance hall color lights, spotlights, and new light sources for industrial and electronic products, etc., it can be said that each of us is in the light of the surroundings. In addition to the above uses, the medical profession has been at the forefront of the use of light, electron microscopes, surgical shadowless lamps, endoscopes, lasers, etc., are inseparable from the light source. Ophthalmology and dermatology have studied the application of light most extensively and are the most vocal about it. While treating light pollution, we have to objectively evaluate and utilize and use light, she is also the patron saint of our vision health. Ophthalmology clinical examination equipment is the most abundant and can complete a variety of tests for in vivo retinal diseases, and these testing instruments on the use of ordinary light or different wavelengths of monochromatic laser as a light source. In treatment, the advantages of various wavelengths of light are also used to accomplish the purpose of conventional surgical treatment, bringing the era of treatment into minimally invasive. Using semiconductors, fuels or other devices, excitation of monochromatic wavelengths or multi-wavelength lasers as a means of treatment to play a light coagulation, vaporization, cutting, or thermal effect, such as 488 nm, 514 nm, 532 nm, 540 nm, 647 nm, 670 nm, 694 nm, 780 nm, 810 nm, 830 nm, 850 nm, YAG and other wavelength lasers. Combining the size of the spot, the amount of energy and the exposure time, etc., these parameters are adjusted between different patients and different conditions to detect or treat the retina in order to control the continued development of the lesion, which is widely used in many common and multifocal clinical fundus diseases, often with encouraging results, as well as photodynamic therapy, which uses a laser to induce a lesion rich in neovascularization through intravenous injection of a photosensitizer after It causes a photochemical reaction to produce free radicals to destroy the vascular endothelial cells of the neovascularization in order to occlude the blood vessels and make the proliferating tissue atrophy to control the expansion and development of the lesions and stabilize the disease. The research results obtained by the medical community need to be taken seriously In China, the safety standards certification of many industries related to the people’s livelihood without the participation of scientific researchers with medical background, resulting in a wide range of different levels of quality in household products closely related to life, good and bad, confusing prices, flying advertisements and different reports. Such as the impact of cell phones on health, eye protection TV gimmicks, the impact of computer radiation, and so on, causing confusion among the people, but also many professionals fell down, the famous domestic tobacco research experts elected as academicians by the national shame of the event occurred is not surprising. Experimental studies on monochromatic visible light for retinal damage have yielded remarkable results in the medical community, and have benefited some patients. However, the results of these studies have not been taken seriously in other aspects of the people’s daily lives besides the clinical ones. Some research results remain on paper, and many practical techniques cannot be widely applied in other industries than medicine. The reasons for this are, on the one hand, that scientific research projects are mostly based on basic research and some practical research is seriously underinvested, and on the other hand, it is also related to the fact that medical researchers are only limited to their own narrow professional scope and do not dissolve into the vivid life and find propositions and research directions from the life. Who escorts the “vision action” Laser medicine branch as a secondary society of the Chinese Optical Society, although established for many years, also made great contributions to the popularization of laser medicine in China, but in the Chinese Optical Society to participate in insufficient. The Vision and Color Committee under the Chinese Society of Illumination also lacks the participation of life science and medical experts. Therefore, it is necessary to change the current situation of insufficient discourse of medical experts in the relevant societies and expand the participation of experts with medical background in the relevant specialties. At the same time, scientific and technological innovation and transformation of results in many fields need to pay attention to the participation of medical-related experts, increase the proportion of relevant medical experts in multidisciplinary crossover, so as to evaluate research results more scientifically and comprehensively, and actively participate in basic research related to people’s livelihood, and change the current blindness of scientific research management and orientation. At the same time, we will strengthen the connection with the media, jointly spread scientific ideas, advocate and popularize scientific knowledge, call for more long-term attention, timely identify problems, effectively improve management, speed up the development of safety standards for the illumination of household appliances on retinal health, continuously improve regulations, perfect industry standards and systems, serve the domestic public, and serve the “Vision Action The “Vision Action” will be protected.
