The visual benefits of blue-violet light filtering

Electro-magnetic radiation constantly surrounds us, but we are often unaware of its presence. Sources of electro-magnetic radiation include items important to our daily lives like light bulbs, electrical appliances, computers, Wi-Fi and smartphones. Our eyes can only detect a small portion of the electro-magnetic spectrum ranging from short wavelength violet light (380nm) to long wavelength red light (780nm) (figure 1).¹⁴  

Approximately one-third of the visible light spectrum is blue light and media headlines have focused on the potential risks of this type of light to our ocular health, but these are not yet fully understood.
