## Overview

The Personal UV Monitor is a customizable, waterproof device that tracks your UV exposure in real time, helping you safely optimize vitamin D production while preventing overexposure.

## Description

The SunFriend is the first customizable activity monitor that helps you manage how much sun you get in any given day as part of a healthier lifestyle. Did you know that when you block the sun from reaching your skin, you prevent beneficial ultraviolet B from penetrating, which is what your body needs to make vitamin D. The same goes when you cover up completely. And vitamin D deficiency is at a pandemic level. In the United States, according to the Skin Cancer Foundation, 1 in 5 people will get skin cancer-despite the increased use of sunscreens. Our solution is to get Safer Sun Time by wearing UVA+B SunFriend. To use, simply set your personal skin color and sensitivity. The SunFriend reads your UV exposure throughout the day-from sun and reflected surfaces, both indoors and out. We recommend setting your sensitivity between 1 and 4 until you get familiar with your choice. When all the LEDs light up and start flashing, you've had your safe amount of UV for the day. If you see any skin reddening after all the LED's have lit up, you know to set your SunFriend at a lower number the following day. SunFriend is waterproof to 3 meters, so it's beach friendly. UVA+B SunFriend empowers people to reduce their skin damage while optimizing their vitamin D. More people are taking charge of their own health. SunFriend empowers people to enjoy the healthy benefits of the sun more safely.

Review: Really Works Well - If pointed directly at the sun and set to your skin type this product is great. I live in Florida and used to get sunburned on occasion since the UV changes based on the atmosphere and cloud cover. Not great for walking around, but when sitting in a chair and with the sensor aimed correctly, it is highly accurate. The negative reviews are from people who expect a miracle device or just don't understand how to set it correctly. For example, the guy who says its crap because he put it inside his car on the dashboard and it didn't register. Did he ever consider that the windshield blocks most if not all of the UV?
Review: Accurate and useful gadget - This thing works as described. I was pretty skeptical at first, but after checking the readings against UV index websites, it seemed to be accurate. One thing to note is that the settings for cumulative exposure are very sensitive - I'm pretty pale and burn easily, but I ended up setting it to 6 or 7 because lower levels it would alert me that I'd met my total exposure within a few minutes on a sunny day. It definitely takes some time to figure out what your level of tolerance is and to set it accordingly. Overall, I'm very happy to have it and it's simple to use. For those reviewers who say it doesn't work because they tested it through glass - UV waves do not penetrate glass, so you're going to get a UV index of 1 inside a car. This shows that it's working properly, not a flaw.

*by K***E on March 24, 2015*

The monitor does not adjust for the amount of skin that is exposed or the amount of clothing covering your skin, so you get only a rough idea of the vitamin D etc that your skin is receiving. I hear the company is coming out with a next generation that will have an app to help make these calculations. I look forward to that one.
