Contrary to the believe of people the rays of the sun are made up of multiple colours such as red, yellow, orange, green, blue and different purple hues. The sun is created from one spectrum to another. One spectrum happens to be full of blue and purple hues whiles the blue and purple hues are located on the other end of the spectrum. The hot coloured hues such as red and orange usually generate less energy whiles the blue light generates higher and more strong energy.

How does blue light impact our eyes?

Given the fact that blue light emanates a greater amount of energy it also has a very significant impact on an individual’s eyes. For most people their day to day exposure to blue light typically derives from the sun. Some believe that they can avoid blue light by remaining indoors but again this is a myth as blue light is also replicated within computer monitors, LED and fluorescent tv screens, smartphones, tablets. When you are indoors but on your electronic devices you are bound to experience blue light as well. With excess exposure, blue light can have a damaging effect on a person’s eyes. Our eyes must be exposed to the light with strict moderation in order to avoid harm.  Too much of everything is not good for you! That saying is definitely applicable in this situation as too much exposure may eventually damage our eyes.

How to stay safe

It is extremely hard to avoid blue light, especially the blue light that derives from our addictive cellular devices, computer screens and more. There are a lot of ways to go around it in order to continue using the electronic devices that you so love and also maintain eye safety. One of them being a computer screen filter that one can use in order to shield the impact of light to the eyes. Another method could be by decreasing the backlight within the computer settings. One must also take breaks from time to time in order to not only rest the eyes but the brain and body as well. When in the outdoors blue blocker sunglasses would definitely work towards a greater protection for the eyes.
