What is Blue Light?
Blue light has a short wavelength and is likely to scatter, causing fatigue of the ciliary muscles, which are the adjusting muscles that adjust the lens, and may cause eye strain.
Blue light can cause a wide range of risks including eye strain, sleep disorders, damage to the retina, dry eyes, stiff shoulders, and headaches.
For those who operate smartphones and PCs or watch TV, it is recommended to take measures immediately with blue light blocking glasses.
