Blue Light Blocking Screen Protectors
The screen protector includes an optical adjustment layer, this layer filters out light that falls into certain wavelengths. Blue Light, the type emitted by displays falls between 300-400nm in the visible light spectrum, the optical adjustment layer blocks an average of 90% of light that falls between this range.
In addition, the optical adjustment layer blocks Ultraviolet (UV) light, the type that causes sun damage and fading to items left outside. UV light falls between 200-380nm on the visible light spectrum, the optical adjustment layer blocks an average of 99.8% of light that falls between this range.
