MBP Space Grey vs Silver regarding eye strain?

For someone who gets eye strain, which color is best? The space grey/gray is less distracting and helps focus on the screen (Mwhich correct me if I’m wrong, couldn’t that be a bad thing? Or is that good?) silver, on the other hand, can reflect light (which, correct me if I’m wrong, might be good in dim lighting but not so good under bright lights). I’m looking for second opinions or results or ideas, etc. I just got my MBP space gray in the mail the other day and am not sure about it. I have a week-and-a-half to return it in order to swap it out. All responses will be greatly appreciated. Thanks!
