Protect yourself from the harmful UV rays from the sun
You may know that the Sun's ultraviolet (UV) rays can 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. UV Detector Sunmate can alert you when the UV intensity exceeds dangerous limits so you can apply proper steps to protect your skin and eyes.
About UV light from the sun
Solar UV rays make up part of the photonic spectrum of light. The ultraviolet region ranges from 10nm to 400nm 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.

Ultraviolet Index Scale
Using the chart provided with the SunMate, you are typically able to cross reference the SunMate indicator with the above reference, which is a standardized UV index reference issued by the world health organization (WHO). This will give an indication of the UV dangers that you are facing, as well as the precautions that should be taken to avoid consequential damage to the eyes or skin.
