Does screen protector really protect anti-relfective coating in Macboon pro Retina display?
My understanding is that the problem with the anti-reflective coating is that it slowly delaminates. I.e. the coating simply comes off the screen. The cause of it does not seem to be heat, but rather pressure from outside sources or just time passing.

In that light, I don't think a screen protector will protect you against this delamination. Any pressure exerted on the screen protector will also affect the coating. Instead I'm worried that the screen protector will actually make it worse as it will put a (small) weight on the coating at all times.
