I used to suffer from bad headaches from the new iPhone screens and started looking into screen protectors that helped my eyes and took off the intensity of the newer phone screens. I have used these OcuShield screen protectors for the past two years on multiple different phones and they are absolutely amazing. They do an amazing job at filtering out the blue light and I have no issues with the new phone screens giving me headaches since i’ve started using them! I had a 15 pro and now a 16 pro max. I will never be going back to the cheap, fake, blue light screen protectors because I know they don’t work like these do. It also is nice that i’ve never had to replace the protector itself either. The adhesive is strong and it doesn’t start to peel or chip easy. It honestly has changed my entire experience with the newer phones and highly recommend them. I have even got my family starting to use them.
