Blue light is a type of visible light with a shorter wavelength, making it emit higher energy. Blue light is not only given off by the sun but also by computer screens, smartphones, flat-screen televisions, and anything that has fluorescent and/or LED backlighting (which includes regular light bulbs btw!).

It is important to understand the effects of blue light because it is not only damaging to the eyes short term, but also long term. Short term blue light effects can make the eyes fatigued and dry. This can contribute to the symptoms of throbbing pain around the eyes - some even suffer from itchy/”burning” eyes. The long term blue light effects can decrease the pigment in the centre part of the vision known as the macula. This can increase the risk of development of macular degeneration - and even blindness.

The sun can actually radiate more blue light than screens. However, with the increasing amount of time in front of/staring directly at screens, we’re starting to see it affect a lot more eyes than the sun. Using blue light filter glasses or screen protectors can help to decrease the amount of blue light that enters the cornea, lens or retina.
