Blue light is artificially generated by energy efficient lighting, computers, tablets, and smartphones. Blue light exposure reaches the back of the eye and can lead to long term damage. Blue light also scatters more than regular light so focussing on digital devices can result in “Digital Eye Strain” with symptoms including blurred vision, dry eyes and headaches. It can also disrupt our sleep cycle when these devices are used less than two hours before bedtime. TrueBlue ® lenses contain pigments that filter blue light and protect eye tissues from damage as well as increase eye comfort and regulate sleep cycles.
