What is blue light?

Blue light is a part of the visible light spectrum. In other words, it is made up of other light in small pieces, among which is blue itself. Remember that light is made up of various shades. So, depending on the color, there are different wavelengths. Thus, it is shorter in the ultraviolet rays and longer in the infrared rays. Blue light is very close to ultraviolet.

What problems can this cause?

There is still no conclusive evidence of eye damage from blue light. However, many experts believe it may lead to premature age-related macular degeneration (AMD). This is a pathology that consists of the slow destruction of central vision. As a result, it causes difficulties in reading or focusing on fixed areas. This disease usually occurs after the age of 60. But experts assure that blue light will cause this pathology earlier. Another possible consequence of blue light is eye fatigue and stress. Studies suggest that spending more than two hours a day in front of a screen can cause these problems.
