I purchased an Ocushield blue light screen protector for my iPad and my iPhone. They were delivered promptly and were very easy to fit. The blue light protection is great, I can use my devices right up to bedtime, get to sleep easily and sleep soundly which was not the case before applying the Ocushield screen protectors. I had to stop using my devices 2 or 3 hours before bedtime, before the Ocushields were fitted, if I wanted to get to sleep quickly and sleep soundly. Compared to other screen protectors, which don't offer the blue light filter, they are quite pricey, but worth the price for the quality, ease of fitting and a good nights sleep.
