    Sunscreenr Sees Unprotected Skin. Sunscreenr shows you where you've missed a spot when applying sunscreen AND where sunscreen has worn off your skin even after sweating, swimming, or toweling off. 

    Can You See Who Still Needs Sunscreen?  Mom did a great job with her kids but everybody needs protection.

    Sunscreenr is a special viewer that changes the way you protect yourself from sun damage. We've taken technology used by scientists and made it easy to see where your skin is covered by sunscreen and where it's not. There are 1 Million cases of skin cancer per year in the US alone, but sunscreen can significantly reduce your chances of getting cancer. Unfortunately, most people only apply 25% to 50% of the sunscreen they should. That's where Sunscreenr comes in.

    Technology to see sunscreen. We humans are pretty amazing but actually our eyes are somewhat limited. Most of us see all the colors of the rainbow but that is just a tiny portion of the light that our Sun makes. UV rays coming from the Sun are invisible to us yet we know that those rays can do us serious damage which is why we wear sunscreen. We designed Sunscreenr specifically to show you the invisible - UV light.

    Since sunscreen's job is to absorb UV light before it hits your skin it looks dark when you look at it through Sunscreenr. Unprotected skin appears light. Sunscreenr is made possible by the combination of several key components: a special filter that removes all light except the part of the spectrum that sunscreen absorbs, a completely custom lens made from special materials and a carefully selected sensor that can actually respond to UV light. We combined that hardware with our proprietary image processing algorithms to deliver an image to you that shows where sunscreen is on your skin.

    Beyond the capabilities of a smartphone. Smartphones and digital cameras are designed to only capture visible light. In fact, they purposely filter-out the UV light that Sunscreenr uses to show you sunscreen. Here’s why:

    • The image sensors in color digital cameras and smartphone cameras have a special filter (Bayer filter) that let's them "see" regular colors (red, green, blue) and that filter just about eliminates the ability of the sensor to respond to the UV spectrum.
    • Lenses in both regular cameras and smartphone cameras are made from materials and have antireflection coatings that actually block most of the UV spectrum.
    • The job of a camera lens is to capture and focus light. Lenses that are made to work for visible light (like in your smartphone) do not focus UV rays properly.
