I purchased an Ocushield screen protector for my I phone when I cracked the existing cover. As a retired GP, I was already well aware of the importance of sleep v stress and the effects our mobiles have to hinder good sleep patterns. I decided to try your shield and was very very impressed with its quality, not withstanding the excellent blue light filter it possesses. I can honestly say that the screen image quality is much better than with my last anti-glare cover and to get the enormous health benefits as well. It is just a no brainer as they say. I have as you are aware changed my i pad and another phone to complete the set and I’m very happy.
