Most screens emit blue light during the day and these blue lights keep us active, which might be problematic especially at night. Fortunately, many devices now offer Night Mode or Night Light settings to change the display hue from blue to a warmer tint.
There’s a high possibility you’re reading this on a device that gives off blue light. People are spending more and more time than ever in front of screens. That being said, should you worry about the blue light coming into your eyes?
The world is full of electromagnetic energy, constantly moving in waves around us and through us.
Different waves are of different lengths, with:

Your eye has structures that keep light from getting in, and UV rays can hurt the light-sensitive retina at the back of your eye. On the other hand, your cornea and lens protect the retina from damage.
Blue light can’t get through these walls. And you’re exposed to a lot of it. The amount of blue light from the sun is much higher than the amount from any one device.
Still, some experts on eye health are worried about the blue light that comes from backlit digital screens and devices. This is because people use them so close to their faces so often.
