I'm in the process of picking up a portable Mac. I had a maxed 11" back in 2013, and loved everything about it....except the screen. It caused a lot of eye strain for me, along with migraines from long usage. I'll be using the portable Mac primarily for college, but also occasional photoshop and Xcode work when I'm away from my 27" iMac. Is the screen on the 13" easier on the eyes than the 11"? I know the panels didn't change from 2013 to 2016, but I haven't had any hands on experience with the 13", let alone long term time to see how the screen is on my eyes. Can anyone with some experience with both give some advice on this?
