The more time we spend with our digital devices, the more harmful we do for our eyes.
What is Blue Light?
Blue light is high-energy visible light that is closest to UV light. Its wavelength is between 385-505nm. It is most commonly seen via natural light and everyday technology.
How to distinguish the good blue light and the harmful blue light?
The beneficial blue light wavelength is between 445mm to 505 mm, while the harmful blue light’s wavelength is between 385mm to 445mm.

The sun’s UV rays increase the risks of cataracts and other certain eye problems. When the situation gets worse, it may even cause blindness.
