Bought two spare lenses. One for me and one for my husband. I was so glad it arrived early. I used it immediately, the same day I received the product. 10 minutes after wearing it I started getting a headache. At first I thought it might be because I was tired and didn't wear glasses before I started working. As I continued to work, my headache became unbearable. I took my glasses off and asked my husband if he had used the new glasses and if he had a headache he said he hadn't tried them yet. my old glasses so I used them to see if the glasses were causing my headache. Of course, I have found that the glasses do not filter blue light as the light passes through the glasses and the test area turns blue.
