Blue Light: how harmful is it, and how to protect your eyes from it?

 

How many of you can recall the concept of dispersion of light belonging back to the standard tenth? Okay, okay, don’t hesitate if you fail to remember it. Even though I know a little! Light is made up of the seven primary hues that we abbreviate call VIBGYOR – Violet, Indigo, Blue, Green, Yellow, Orange, and Red. Each shade of light possesses its energy as well as a wavelength. The rays that accompany the red end have less energy and longer wavelengths. On the contrary, blue-sided rays have more energy and shorter wavelengths. Lights having their power and wavelength has its advantages and drawbacks.

In this article, I will make you learn about the sources of blue light dispersion, the pros, and cons of blue light emission. In a real sense, blue light is the color that forms a part of the “visible light spectrum.” Let’s see how the very light being a blessing in the morning transforms to turn a curse at night for a human eye.

Sources of Blue Light Technology:

The sun is the chief source of light. Ethically, the sun is the largest source of blue light emission even. Here we talked about the natural source. Whereas, the artificial sources of blue light include:

1. Compact Fluorescent Light (CFL bulbs)
2. Fluorescent Light
3. Flat-Screened LED televisions
4. Light Emitting Diode Light (LED)
5. Computer Monitors (Screens)
6. Laptops
7. Smartphones
8. Tablets

The absorption from these sources depends on screen proximity. Humans expose themselves too near to the digital devices, and the screens emitting blue light make its way! Despite the fact that the blue light emission is more prominent from the sun than the digital devices, the later affects more because of more closeness to it. A study says that the eyes of children absorb blue light more than the adult eye does! Parental suggestion – Keep your child away from the gadgets strictly.
