A company called UVSunSense has developed a wristband, that helps people avoid overexposure to harmful ultraviolet radiation from the sun, is now  available and will soon help families all across America reduce the risk of skin cancer.

The UVSunSense wristband is a sun-sensitive gauge. Wrapped around a user’s wrist, the wearer then applies sunscreen to their body, as well as the wristband, before going about their outdoor activity. The band then changes color to let the wearer know it’s time to reapply sunscreen,or to get out of the sun. It’s really that simple!

UVSunSense is designed to work with sunscreens of SPF 15 or higher, and will change color at different times depending on the SPF level. UVSunSense is designed to be used in salt, fresh or chlorinated water, and in showers – thus giving an accurate reading after outdoor activities like swimming, running or just playing in the backyard. via uvsunsense.com
