Do you know that exposure to blue light can affect your health? Do you know it is one of the leading causes of the deterioration of eyesight?

The more exposed you are to blue light the more your eyes suffer for it. Not many people know what blue light is or how potentially damaging it is to them So, let’s start from there. What exactly is blue light, where does it come from, and why do we all need to limit our exposure to it.

What is blue light?
Blue light is one of the colours in the visible light spectrum. The other colours in the spectrum include red, orange, yellow, green, indigo, and violet.

It is estimated that we spend above 11 hours per day staring at blue light-emitting screens. Our phones are always within reach, and these gadgets emit lots of blue light. Laptop and desktop screens are also notable culprits.

Blue light has a short wavelength, which translates to a high frequency and consequently, high energy. Because of this energy, blue light can pass through the eye to the retina, causing damage to the delicate tissues of the eyes.

It interferes with our sleep and causes defects in healthy sleep physiology. Studies have shown that people who are exposed to blue light 2 hours before bedtime tend to have poorer sleeping experience than people with reduced exposure.

Where does blue light come from?

Blue light is all around us and comes from almost everything that emits light, with sunlight being the major source.

Other sources include smartphones, tablet screens, LED TV, fluorescent light, and computer screens, among others. The proximity and hours of screen time on phones and gadgets raises a huge concern over the long term effects of blue light on the eyes and health in general.

Effects of blue light
