Negative Impacts of Blue Light

-

Did you know that Blue light can affect your eyes? Unfortunately, medical research has shown that Blue light is harmful to your eyes. 

What is Blue Light?

Sunlight consists of seven colours in the visible spectrum—violet, indigo, blue, green, yellow, orange, and red. And each of the colours has a different energy and wavelength. Blue light has shorter wavelengths and higher energy than the other colours of the spectrum. Some medical researchers have established that the human eye is prone to damages from the short wavelengths, extending from 415 to 455 nanometres, of Blue light. Apart from the sunlight, your eyes can get exposed to Blue light from fluorescent tubes, CFL bulbs, LED bulbs, flat-screen LED televisions, computer monitors, smartphone screens, and tablet screens.

 


How Blue Light Affects Eyes?

 

Research has shown that you can suffer from eye strain or retina damage when you expose your eyes to Blue light excessively. 

Blue light from digital device screens can reduce the contrast. As a result, it can cause eye strain. And the symptoms usually include sore eyes with focusing difficulty. 

Prolonged exposure of your eyes to Blue light can lead to retinal cell damage, affecting vision.


Protecting Your Eyes from Blue Light

Despite the negative impacts of Blue light, you cannot escape exposing your eyes to the light due to the digital age we are in today.

But, you can reduce the time you spend in front of digital screens. Also, you can frequently take your eyes off the screens to protect your eyes from Blue light.
