Question:
What harmful rays do digital devices emit?
Answer:
Blue Light rays emit from digital devices which are harmful.
Explanation:
We can understand how blue light rays harm us by some points.
1. Light travels in waves and is made up of electromagnetic particles and every wave has different energy which they emit and also their length is different.
2. The shorter the wavelength more will be its energy.
3. There are many wavelengths which have different colours and all this makes electromagnetic spectrum.
4. Our eyes are sensitive to visible light which is a part of electromagnetic spectrum.
5. Blue light has a short wavelength which means it will have higher energy which will affect our eyes and is harmful for us.
6. Artificial blue light from digital devices affect us but, not the natural blue light because our body used natural blue light to maintain sleep and waking up cycles.
Blue Light
Explanation:
The display screens of computers, electronic notebooks, smartphones and other digital devices emit significant amounts of blue light. High energy blue light has short wavelength and hence scatters more easily than other visible light, so it is not as easily focused. When you're looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual noise reduces contrast and can contribute to digital eye strain. Blue light exposure may increase the risk of macular degeneration.
