Our world is illuminated and energized from the light released by the sun streaming earthward in the form waves. Those light waves are similar to the movement of water in the ocean, except solar waves, originating 90 million miles away and taking about 8 minutes to get to Earth, take on distinct wavelengths. Three of those wavelengths, known as UvA, UvB and UvC are invisible and have been associated with the damaging, and sometimes deadly effects conventionally attributed to solar radiation.

UvC, the shortest of the three wavelengths, is associated with skin cancers and is considered to be the most dangerous, but (theoretically anyway) the earth’s atmosphere offers protection.
