Positive Effects
Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Modern science has incorporated the visible light spectrum into many electronic devices in use today. Every device that has a viewable screen creates and emits visible light, which your eye perceives as a picture. Such technologies include LCD computer monitors, cell phone screens and TV screens. Plants rely on the energy provided by visible light to power their photosynthetic cycle, allowing them to make simple sugars from components found in their environment. Visible light, such as sunlight, play an important role in the synthesis of neurotransmitters in humans. Without visible light, humans may undergo depression and brain damage.

Negative Effects
A study by Taylor et al. in Archives of Ophthalmology links excessive exposure to visible light, especially in the blue spectrum, to age-related macular degeneration. Light in the visible spectrum can cause photodegradation of pigments and colorants. While not as powerful as UV light at causing fading, blue and violet light can cause a similar though lesser effect. In many plastics and polymers, sunlight can cause a breakdown of the object's molecular structure, making the object brittle and opaque until it is destroyed completely.
