With the Nurugo SmartUV, consumers not only get a convenient smartphone attachment, but they also get a de facto refresher in a middle school science class topic. The camera captures light on the ultraviolet spectrum and displays it on users' smartphones with the help of an accompanying app, letting users see the world with a new pair of eyes.
Though people often conceptualizes light as the rays that allow one to see the world, light exists beyond the frequencies that human eyes are able to detect. Light with a frequency just higher than the eye can detect is called ultraviolet light, and the light in this portion of the spectrum is the same that damages people's skin and eyes. Thus, one of the biggest benefits of the Nurugo SmartUV is that people can use it to check how well they've applied sunscreen or whether their sunglasses are actually UV-protected.
