Light is composed of both visible and invisible rays. This is called the electromagnetic spectrum. We’re all aware of the harmful effects of the invisible range like Ultraviolet light. But did you know that visible light can have negative side effects as well?
Visible light is comprised of different colours of differing intensities. These are Red, Orange, Green, Blue, Indigo, and Violet.
Blue light being at the lower end of the electromagnetic spectrum, has high energy and can be damaging to the eyes. Moreover, our eyes are not good at blocking blue light. Some negative side effects of blue light are eye strain and macular degeneration.
Most digital devices including computers and smart phones emit blue light.
There are lenses that can protect the eyes against blue light. Come into Romin Optical for more information on these lenses.
