The Features of Blue Light Filter
There are various light spectrum ranges that are visible to our naked eyes – blue to red. You will find the blue light on the edge of the spectrum, which is synonymous with an invisible UV light already. On the other hand, blue light is known as the “high-energy visible light” or HEV. It has a shorter wavelength than the colors which are near the red spectrum that usually hits our eyes. And that’s how it always works.
Here’s an illustration from Gunnar:
As you can see, the blue light lies on the advantageous part of the line and this is from the sun. This ray is responsible for controlling the cycles of our sleep. It also has a say on our memory. Exposing our eyes to these rays can be very dangerous as they are not natural. This is why you should be conscious.
There is a current work that backs up the said claim. It focuses on the effects of extended blue light exposure which comes from the devices that we use on a daily basis. When we are around them all the time, they would bring changes in our retina such as the Age-Related Macular Degeneration. This originates from the blue light that the sun emits. As an effect, we might experience headaches, eye strain, and uneasiness when we sleep.
