Mackbook Pro Retina and health? I just changed from a normal macbook pro to the gorgeous mbp retina display, I have been using it 3 days and Im starting with headaches and eye pain!
I really dont know wats happening, I mean the display is beautiful but although I use it in the minor bright Im still having eye and head issues! 

If anyone can help me with an experience or something it would be really nice.
Because objects are smaller a sharper your eyes are trying to focus on that.

The constant focusing strains your eye muscles, resulting in eye pain and headache.

I would see a optometrist and get a prescription, or just buy a reading glasses at any store, starting a 0.5 strength to see it that helps (they cost around $5)
