Light Spectrum & Blue rays/ Blue light

In the visible light spectrum, Blue light waves have estimated wavelength between 380nm-500nm. Though among the shortest, they have highest energy wavelengths.

Harmful to human eye

Because Blue rays are shorter, these high energy visible wavelengths flicker more easily than longer, weaker wavelengths.


This kind of flickering creates a glare that can reduce visual contrast and affect sharpness and clarity. 
This flickering and glaring may be one of the reasons for eyestrain, headaches, physical and mental fatigue caused by many hours sitting in front of a computer screen or other electronic device.  
Human eyes' natural filters do not provide sufficient protection against  blue light rays from the sun, digital devices and fluorescent-light tubes. Prolonged exposure to blue light may cause retinal damage and contribute to age-related macular degeneration, which can lead to loss of vision.
