This is a good quality screen protector for Mac with Retina Display. As you know, one of those old Retina Macs has its anti-glare coating peeling off over time, causing it to peel off. The way this screen protector sticks to the screen doesn't appear to be regular adhesive, it's something else that doesn't stick to the screen or leave any residue. As for the screen protector itself, I didn't notice any difference with or without the blue light filter, but that might just be me. It's also very reflective, but that doesn't bother me. This is a good quality product.
