Visible light is typically pretty harmless.
However, some light can be so intense that it can damage the receptor cells in your eye causing temporary or permanent blindness.
High powered lasers can also be damaging and will cause burns.
What are the negative effects of visible light?
Negative effects: these include that different colours can cause different emotional responses. Excessive exposure to visible light, especially in the blue spectrum, links to age-related macular degeneration. Light in the visible spectrum can cause photodegradation of pigments and colorants.
What are the disadvantages of visible light?
Disadvantages: If there is too much exposure to visible light, it may cause blindness or eye damage. It can also hurt your retina and even damage it. Definition: Ultraviolet rays have wavelengths that are too short too see. They are electromagnetic waves with wavelengths just shorter than those of visible light.
Can visible light cause blindness?
UV rays have higher energy than visible light rays, which makes them capable of producing changes in the skin that create a suntan. These rays also can cause sunburned eyes — a condition called photokeratitis or snow blindness.
Why is light dangerous?
That is the basis for all the blue light blocking talk you may have heard. If you get to about 1,000,000 nits or higher, the total energy being absorbed at the retina is enough to cause thermal damage to tissue in the retina. If you filtered out all UV and infrared, the visible light would still be dangerous.
