What wavelength is bad for humans?
UV and blue-violet light (380 ? 495 nm) are the wavelengths with the highest energy, and are thus potentially the most harmful to the human eye. Why do blue lights look blurry? By rayleigh scattering law, the amount by which a ray of light is scattered is inversely proportional to the 4th power of its wavelength. As blue light has a smaller wavelength than red light ,thus it's scattered more and hence seems blurry.
Also, what wavelength of light is harmful?
UV-B light (290-320nm) causes sunburns with prolonged exposure along with increasing the risk of skin cancer and other cellular damage. About 95% of all UV-B light is absorbed by the ozone in Earth's atmosphere. UV-C light (100-290nm) is extremely harmful and is almost completely absorbed by Earth's atmosphere. In respect to this, is blue light more harmful than uv? Blue light has very short, high energy waves. In fact, they're only slightly longer and less powerful than UV waves, which are too short for people to see with the naked eye. Health experts have warned against the harmful effects of UV rays, which can damage your skin and your eyes.
Thereof, does blue light from screens damage eyes?

It's also the color that is most commonly emitted by screens on our computers and smartphones. The blue light from these electronic devices may trigger migraine attacks.
