Visible light plays a role in human health and well-being. Let's discuss the various ways visible light affects humans.
How Does Visible Light Affect Humans?
It affects us in various ways:
The photons of the visible light can be absorbed by the melanin, heme, and opsins. It helps to function in the human skin by activating the chromophores i.e. melanin, heme, and opsins. Visible light may cause so much damage to human skin including erythema or pigmentation.
It can also damage our DNA by producing different reactive oxygen species. On the other side, visible light can affect the pituitary gland and pineal glands of the human brain. The light activation process can decrease the different substances like melatonin, norepinephrine, and acetylcholine. Visible light also increases the dopamine levels of the human body.
The visible light can create photochemical effects in the human eye specifically on the retina. Visible lights also contribute to human sight and help us to detect the colours and shapes of a particular object present in our environment. A high level of visible blue light may cause the ocular damage that develops the macular degeneration.
