What is Blu-ray? What harm does it do to the human body?
Sunlight contains red, orange, yellow, green, and blue rays, as well as many shades of each color, depending on the energy and wavelength of the individual rays. Blue light has a wavelength between 380-500nm and is a type of visible light. Most notably, the display screens of computers, laptops, smartphones, and other digital devices also emit large amounts of blue light. The amount of time people spend using these devices, and the proximity of these screens to the user’s face, can have significant long-term effects on eye health. Blue light with wavelengths between 380-440nm is potentially damaging and may cause retinal damage. Cataracts and macular degeneration will also increase.
Do anti-blue light mirrors really work?
It is impossible to completely isolate blue light. The complete absence of blue light is equivalent to color blindness. In today's information age, people spend more and more time in front of electronic products, which take up about 8.5 hours of their daily life on average. Therefore, filtering blue light through lenses can reduce excessive fatigue caused by blue light on the eyes and properly protect the retina, making life healthier.
