They do not work!
Save your money. I used a spectroscope to determine what wavelengths of light they filter and it turns out that they do not. They send a little blue light and a " light sensitive card" , but when observed with a spectroscope, you can see that they are just crap plastic. I have a video as well, but this picture should suffice.
