I've been using the Macbook Pro (Retina, 15-inch, late 2013 model) for 1.5 years now, and I've noticed my eye sight has dropped significantly since then. The time I spent on computer was the same as before (about 14 hours/day, I'm a programmer). Before this, I was using a desktop with mid-tier screen, and had no problem. Now my eyes get easily tired and strained after 30 minutes of looking at the Macbook screen.
If you have experienced similar problems, I would really appreciate if you can share any advice about it, and possibly solutions? My work is on programming, it hard for me to switch to another career :s
