QuantaDose® Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card

Tested all my summer clothes. Works great.

The media could not be loaded. This is a great tool that I find to be an absolute must for testing all kinds of glasses worn outdoors to ensure they protect my eyes from damaging UVA and UVB rays. It is very easy to use, and the maker has a detailed explanation page on their website; see the QR code on the back of the card (and in one of my photos). While it also tests for UVC to test the veracity of sanitizing equipment, I got it primarily to test glasses along with a blacklight.I did a little research and spoke to the creator and owner of QuantaDose UV detection cards, and also read up on “Protecting your eyes from the sun’s UV light” published 7/5/22 by the US government’s National Rye Institute (NEI) on the National Health of Health’s (NIH) .gov website. According to this article, UVA and UVB can be damaging to the eyes and the article states, “Look for lenses that provide 99 to 100 percent protection from UVA and UVB or marked as having a UV400 rating.” In testing glasses, I have learned labels cannot always be trusted and sometimes it can be in the user’s favor (and in some cases there is no label at all). I did a video (1m 45s) testing these sunglasses and other glasses regarding UV protection with the QuantaDose card and a 365nm blacklight.VIDEO – My short (1m 45s) attached video shows the following:(Note I wore UV400 glasses while using the blacklight for this testing video.)1 - The front and back of the card and 365nm blacklight2 - Showing how the card turns violet when exposed to longwave UVA and UVB light3 - Testing a pair of clear safety glasses that DO protect against UVA and UVB light4 - Mislabeled glasses that do NOT protect from blue or UVA and UVB light5 – Tests on all 3 pair of these sunglasses; they DO appear to protect against UVA and UVB lightGiven what I learned about eye health and UV light, I will be testing all of our sunglasses, work glasses, etc., for UVA and UVB protection for wearing outside (even on cloudy days), and all indoor reading and other glasses for blue light protection (using a blue light and a blue light detection card) …the 365nm blacklight I got and this UV detection card to me are a necessary and great investments.The credit card sized card is made of nice quality plastic and is the 3rd iteration (and most versatile) of QuantaDose’s UV cards. To me it worth far more than the $10.99 US price at the time I purchased it and is earns a well-deserved 5 (plus) stars in my book.

I am an engineer, yet I had to read instructions multiple times to understand how to read it. There are 5 areas on the front:1. Purple at the top2. Left semi-circle3. Righ semi-circle4. Middle circle5. Small square in the upper rightwhich are sensitive to different wavelengths and intensities. Additionally, there is a sensitive panel on the back.Frankly, for most people, it is overkill. If you want to measure natural UV and perhaps see how different transparent glasses/films protect from it, you only need #1. On the other hand, if you are testing industrial UV flashlights and know how many nanometers your spectrum is, I guess this card is for you.

I use the 6 in 1 Quantadose UV test card to test any pair of sunglasses I purchase to verify UV protection. While the card is easy to use, the design layout of the test areas seems a bit redundant to me - not sure why 5 separate test zones dedicated to the presence and/or intensity of UV-A/B and UV-C light couldn't be consolidated into 1 combined presence and intensity zone for UV-A/B and one for UV-C - but my use cases are limited so perhaps this layout is more useful to others.

Looks like it worked but not sure what it means. Looks like it might be a weak UVC to me. Let me know what you think. I was going to send this picture to the company but they don't seem to take pictures. Also It only seems to work while directly under the light. Once removed it seems to disappear immediately
