1, JD.COM, Harbin Institute of Technology's bio-safety eye lamp, Taobao price, 1999 yuan. Seven harmful light indicators, such as actinic ultraviolet, near ultraviolet, blue light, small light source, retinal fever, weak visual stimulation and infrared radiation, have reached the "exemption" level of photobiosafety of the International Electrotechnical Commission. It is an innovative product to meet the demand of photobiological eye protection lamp, which can not only protect students' vision health, but also effectively inhibit the growth of juvenile myopia rate, and is useful.

2. Photobiological safety material adopts transparent design, which perfectly removes optical radiation and effectively ensures sufficient illumination. Compared with common translucent lampshade materials, it can not remove light radiation, but also has comprehensive performance improvement. This technology has the functions of removing harmful light radiation and protecting vision health.
