The Detecto-Ring consists of plastic UV sensing beads and a colored key ring. The white beads will turn color when exposed to UV-A or UV-B 50,000 times.

Not all shade or clothing protects you from sun exposure. Test your exposure with the UV Detecto Ring and learn when you may be at risk. I recommend you place the ring on your key ring so it is always handy to check your UV exposure. What you learn may be startling! For example:

1. my ring turned intense color while I was sitting at an outdoor cafe in the complete shade of a tall building, but apparently fully exposed to reflected light from the building across the street!

2. I placed my ring in the pocket of a 1 year old sun protection garment and it colored a little, meaning that the sun protection of the garment was wearing out and I needed to replace it.

Try it and see how well you know your sun exposure risks.

The Detecto-ring is a teaching tool and is not a medical device that can be used to guarantee sun safety.

What My Customers Say:

"Those little beads are fun. I popped them out and showed people and they said it's magic. I thought we would never get home. I was testing the dash board of the car, this window and that window. I even took them in the shower to see how much light comes through the window and there was some." 

"Those beads were fun and surprising. I was so surprised to see that in the full shade of a building how much sun there is. I thought shade protected you. I was also surprised and pleased that the gloves I use to work outside and drive the tractor didn't let the sun through; the beads stayed white when I put them under them and drove the tractor all day."

UV ring Review by Rich

I got the uv ring . I got my windows Timorese with llumar film and my ring stays 99 percent clear showing that Timor actually blocks 99 UVA rays ! That’s a lot better than sunscreen .

I then did the ring in my sister car who doesn’t have tint added and the ring changes color a lot , then when outside it changed color even more vibrant !

Everybody should have one Review by Linda Hopson

I was shocked at how much UV i was exposed to when I thought I was "in the shade". In my lanai, very shaded and 8' from the non-shade part, I was surprised to see that my feet were getting lots of UV when propped up on the ottoman. Moving closer to the sunny area, but still supposedly in the shade, I was again surprised to see how much UV my entire body was getting. I have them on my key chain and when driving (in a car that does not require the key to be in the ignition) I held it up to the left side of my face and oh wow. I now won't forget to wear sunscreen even when I'm in the car. And hand hanging off the top of the steering wheel? might as well be sitting outside. Everyone you know should have on these. Even on cloudy days when I am swimming outside, I intellectually know there is still sun getting through, but I leave my keys at the end of the lane and am surprised at how MUCH UV damage is still coming through--just as much as when the sun is fully shining.
