What's special about Sunscreenr™?
Can't I just use my smartphone camera or digital camera? Smartphones and digital cameras are designed to only capture visible light. They purposely filter-out the spectrum of light used by Sunscreenr to "see" sunscreen. For those those want to know the technicalities of 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. - Lens elements in regular cameras and smartphone cameras are made from materials that have antireflection coatings that actually block most of the UV spectrum. - Camera lenses are designed to capture and focus light. Lenses that are made to work for visible light (like in your smartphone) do not focus UV rays properly.
Isn't Sunscreenr™ just a fancy lens?
No. 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. That hardware is combined with our proprietary image processing algorithms to deliver an image to you that shows where sunscreen is on your skin. Protected areas appear dark and unprotected skin appears light.
Can I use Sunscreenr™ with my eyeglasses or sunglasses on?
Yes, although some may find that the display on your phone appears sharper with glasses off. It all depends on your eyes and what kind of prescription you have. We have worked with an optical engineer and have consulted with several optometrists to make Sunscreenr as easy to use a possible for the broadest range of people. If you use Sunscreenr with your sunglasses on you may find that the display looks slightly dimmer.
How long will the battery last? How is it recharged?
Sunscreenr runs off of your Android Phone's battery, so it never needs a charge. It also does not drain much battery power from your phone. Just be sure to unplug it after use.
Will Sunscreenr™ work for people of all skin tones?
Yes! The contrast between unprotected skin and protected skin is less dramatic than for people of lighter skin color. Unprotected areas will appear lighter and areas covered with sunscreen will still appear darker. Sunscreenr's algorithms work to make this contrast as large as possible.
Does Sunscreenr™ see all types of sunscreen?
Any Broad Spectrum sunscreen (cream, spray or powder) that's at least SPF 15 will be visible through Sunscreenr™.
I hear that most people don't put on enough sunscreen. Can Sunscreenr™ show me areas where my coverage is too thin?
Yes! Areas of thin coverage will not appear as dark as areas that are well covered.
What if there's nobody around to check out my sunscreen coverage?
No worries! Just point your Sunscreenr camera at yourself and check your coverage on your phone.
How can I avoid the harmful effects of the sun?
Staying out of the sun is the best way to avoid sun damage, but most of us go outdoors regularly. So when you go outside, take these precautions:
- Always wear sunscreen. Apply it on your skin every day. Make it a habit, as you do with brushing your teeth.
- Avoid sun in the middle of the day, from about 10 am to 3 pm. The ultraviolet rays, which cause sunburn, are strongest during this time.
- Wear protective clothing. When you do go outdoors, especially for long periods in the middle of the day. Long sleeves and pants, as well as a wide-brimmed hat, help protect your body against the sun's harmful effects.
- Wear sunglasses that filter UV light.
