What is the blue ray?
Light is an electromagnetic radiation with wave-particle duality. The shorter the wavelength, the higher the energy and the stronger the penetration. (E.g. gamma rays, x-rays, ultraviolet rays Lights, etc.)

Visible light and blue light
The range of visible light is usually from 380nm to 780nm



Mortality for retinal cells in different wavebands in light condition

Phototoxicity test Phototoxicity test:
Light conditions: Simulating the intensity of natural light reaching the retina.
Illumination Time: 18 hours.
Comparison of retinal pigment epithelial cell mortality between light and dark environments.
Experimental conclusion: the most harmful wave bands are focused around 435±20nm.


Where is the blue ray?
Blue ray is everywhere.
Outside: Sunlight is the main source of the blue ray.
Inside: LED light, screens of computers, Phones, and other digital equipment can emit plenty of blue rays.
