This blue light filter saved my job. I got dizzy looking at the screen. I never thought that one product could make such a difference. The dizziness stopped while I was using my computer. The day it arrived I got so dizzy that I tried to put the case on while the computer was on. Now I know that I had to turn off the computer first. I have a few blisters underneath but it doesn't really matter. If I had followed the instructions, everything would have gone perfectly. My fault, not the product. Now I want one for my laptop and two TVs at home. In the last two years I have become very sensitive to LEDs. The product serves its purpose. I had no idea how sick I was from the computer screen. I had an MRI and CT for dizziness looking for a brain tumor. Then my doctor mentioned my computer and photophobia (a form of migraine associated with light). I didn't have the usual migraine headaches. I would just get dizzy. It has made my life at work so much better.
