My MacBook Pro retina 13 inch is causing headaches?

Hello all,
I purchased a MacBook Pro 13 Inch Retina Display last week or so, and I noticed that it is really causing pain to my eyes and causing me headaches and eye strain, now I did check all the resolution and brightness, but nothing really seemed to work!
Please note that I put a screen protector on it a couple of days ago, so I was wondering i that is the issue?
Also if I go and return it or exchange it, should I get the MacBook Air Non Retina or Pro Non Retina??
Please give me some advice here since I am suffering from headaches, and I am not sure if it the screen protector or the Built-in Retina Display that is causing it!
Thank you

have you considered having your eyes checked? seriously...
