I had severe eye fatigue when I made the jump from galaxy s10 plus to iPhone 16. I tried all settings possible including reduce motion, brightness, tint etc but I couldn’t use the phone for more than 12 minutes before my eyes started to hurt. On a Reddit thread, I read someone swearing by Ocusheild. I didn’t have high hopes at first as I was under the impression that not much can be done about blue light emission from screens. I placed an order and the delivery was smooth. I was nervous about applying the screen protector myself. However, I was pleasantly surprised by the inclusion of a mold that basically fit the phone model perfectly. After that it was a simple task of placing the phone face down on that mold and pressing in. Quite a satisfying experience. From that point onwards I am able to use my phone normally. 5 stars and I will surely buy again for all my future devices.
