The UVA+B SunFriend UV detection bracelet is ugly at first sight. After consulting relevant materials and carefully reading the product manual, I have a new understanding of UVA+B SunFriend.

In 2011, NASA scientist Shahid Aslam invented a UV monitoring bracelet based on the research of UV and skin cancer. At the "Future Design Competition" held by NASA TechBriefs, the concept product won the voting award of the best consumer product and the most popular award 。  

Later, Shahid Aslam and partner Edgett led a team of engineers, scientists and marketing personnel to jointly start this UV monitoring bracelet called SunFriend. In 2014, SunFriend newly developed UVA+B SunFriend wearable UV bracelet, which was displayed at CES 2015 in Las Vegas.

It is reported that the medical expenses of the United States due to the lack of vitamin D each year are up to 129 billion dollars. And 90% of vitamin D is obtained by sunshine, so vitamin D is also called "sunshine vitamin". However, excessive sun exposure may lead to a high incidence of skin cancer.

SunFriend's goal is to prevent the increase of vitamin D deficiency, but also to reduce the incidence of skin cancer. This product, inspired by NASA technology, is equipped with patented UV , monitor the surrounding environment every few seconds, measure the ultraviolet light reflected and refracted from the environment, record the UVA and UVB in the next day's light, and test the skin sensitivity

Users can take SunFriend to the seaside, play golf, or go swimming. When SunFriend is worn on your wrist, the LED light on the bracelet will flash to let you know whether you have received enough vitamin D. However, if the indicator lights on the bracelet are all on, it means that the sun is burning your skin. At this time, if you continue to bask in the sun, it may lead to a high incidence of skin cancer.
