I absolutely love my Ocushield so far! The headaches I was having from the blue light have decreased dramatically. I would give a tip though: I was advised to cut to size with a Stanley cutter as opposed to scissors. I did this with a fresh, sharp blade and even with my best effort to make my lines straight, the shield did not do well with the Stanley cutter. My cuts are jagged and don't look good at all. For my second shield I used sharp scissors and it looks perfect! So one of them the cut looks awful but I learned my lesson and will deal with the eye sore since it is at least performing at a high standard.
