Bests & Worsts Reviews from Amazon

Just received these, and I tested them on an external website. Amazon won't let me include the link, but you can search for it with the terms "blue light filter test for glasses" and the link I used had this in the title: "How Effective is your Blue Light Filter". The test shows two different color spectrums, and if you have normal color perception and your monitor can display RGB, then BEFORE you put the glasses on, the two spectrums should appear very different. If the glasses effectively filter out blue light, then the two color spectrums should appear identical once you put the glasses on. There was zero effect with these glasses - the two spectrums were different from each other (i.e., blue light was still reaching my eyes) both before and after putting the glasses on. I also showed the included blue flashlight and test card (which are included with the package) to my husband, who's more science-y than me, and he said that the test spot on the card is reacting to invisible UV light, not visible blue light, and that's all that the glasses are blocking. Maybe invisible UV light ALSO affects melatonin production, I don't know, but I do know that visible blue light *definitely* inhibits melatonin production, and these glasses do not prevent it from reaching your eyes. I was looking for something to filter out blue light, to support melatonin production in the evening, and to help me fall asleep easier/quicker at night. These glasses didn't fit the bill. After doing some more research, I ordered a 3 pack of the Uvex Skyper Blue Light Blocking Computer Glasses, which are used in lab studies to research the impacts of filtering out blue light.
