I would say they have a more tinted look. I don't like them because my friends and I watch movies at work when it is slow so it makes it hard when everyone has to be straight on with it. They work great for the purpose but you may have to turn up your phone brightness.
Its got an anti-glare look to them. It also cuts down on brightness in general, and affects the sensitivity of the screen. I have one on now from powersupportusa but im thinking of taking it off and replacing with a regular anti-glare proteector.
