I'm getting eyestrain headaches in my right eye while watching my Macbook Pro 13 inch in bed. I just bought the computer a few weeks ago, and I have a couple of theories. I've watched movies in bed on my HP Elitebook with the 14 inch screen, no problems, but it has a very dim, and matte display, the Macbook Pro has a VERY bright, LED backlit display. So, I'm wondering... Is it the bright LED backlit display? Is it because it's glossy and not matte? Is it the 13 inch size? Should I return the 13 and get the 15? Or??? I've tried moving the laptop further away from my eyes to no avail. I turned the brightness down and that didn't help too much... Maybe I should turn some lights on in the room and not watch it in the dark? FWIW, my vision is 20/20 in the left, and 20/30 in the right, so maybe there is something else going on with my vision, but I got my eyes checked last week and he said I am still on the "cusp" of needing glasses.
