About Ultraviolet Solar Radiation

Solar UV rays make up part of the photonic spectrum of light. The ultraviolet region ranges from 10nm to 400nm (nanometer) and can be further divided into UV-A, UV-B, and UV-C. UV-A rays range from 320nm to 400nm, UV-B rays range from 280nm to 320nm, and UV-C radiation has wavelengths less than 280nm.
UV-A is linked to sunburn, accelerated skin aging, and damage to DNA. UV-B also causes sunburn and is related to snow blindness, skin cancer, and immune system suppression. UV-C is extremely dangerous to plants and animals. However, it is absorbed by the ozone layer and does not reach the ground unless the ozone layer is destroyed.

Product Description

It is a well-known fact that the sun's ultraviolet (UV) rays cause skin aging, sunburn, and skin cancer. Unfortunately, your eyes can not easily determine the intensity of UV radiation especially on cloudy and snowy days. Weighing less than an ounce and smaller than a pack of gum, the SunMate can be worn to the beach, the mountains, or anywhere outdoors. It will alert you when the UV intensity ex-ceeds dangerous limits so you can apply the proper steps to protect your skin and eyes.

Reducing the risks of overexposure to ultraviolet rays
Osun’s SunMate alerts the user of a possible over-exposure to ultraviolet rays from sunlight. This handy device is easy to understand and does not need technical background. The LEDs indicate the UVI levels according to the chart below. As you may notice, the gaps between the ranges in the table above are closed to make the detection continuous.
When in the sun, always:
* apply sunscreen
* wear proper clothing
* wear sunglasses
* avoid midday sun
* wear a hat
* remain inside when UVI is high

About The Ultraviolet (UV) Index

The National Weather Service (NWS) and the Environmental Protection Agency (EPA) developed the UV Index to help in planning outdoor activities. It can be found on almost every weather forecast.
The UV index numbers developed by NWS and EPA indicating the intensity of the sun are shown below. Exposure levels are given on a scale of 0 to 10+, with 0 indicating minimal exposure and 10+ indicating very high and dangerous UV levels.

Minimal Low Moderate High Very High
0 - 2 3 - 4 4 - 7 7 - 9 10+
