UV Index

The UV Index (ultra violet index) is an international standard measurement of the strength of the sun's harmful rays at a particular place and time. The scale was created by Canadian scientists in 1992, then later standardized by the United Nation's United Health Organization in 1994.

The UV Index is used primarily to inform the general public on how they should appropriately protect themselves from the sun's UV rays. Long exposure to the sun's rays, without adequate protection, can lead to sunburn, premature skin aging, melanoma, skin cancer and more. The UV Index scale indicates the use of sun protective clothing and/or accessories to minimize harmful exposure to the sun.
