The NIH says it’s also used to reduce the number of people who need eye surgeries and is currently used by more than 10 million Americans to prevent eye damage.
Blue light is emitted from fluorescent light bulbs.
The NIH says blue light is a form of electromagnetic radiation, which is emitted when an object emits a low-energy signal that is converted into electricity.
That signal travels through the air and travels through nearby objects in the same way as a radio waves.
The radiation can cause damage to the retina and brain, and is a risk factor for Alzheimer’s disease, schizophrenia, and other degenerative diseases.
It also increases the risk of a person being exposed to electromagnetic radiation from other sources such as cellphones, computers, television, and radios.
