This is an interesting question, but could we make this into a real poll?<p>I'm happy to do this (you need above a certain karma threshold to create polls - I forget what it is) but if the OP would rather not then that's fine too, and I'll leave it.
I look at a computer screen 8 hours a day at work, drive an hour home, and look at a screen another four to five hours.<p>This past week, I had a weird experience where there was a white spot in my vision that prevented me from being able to read. Any particular letter or number I focused on couldn't been seen. It only lasted for about fifteen minutes but left me with a headache that lasted a couple of hours. According to my eye-doctor, it was probably an ocular migraine.
Good question. Even when I take a break I head for a sports bar. Drive time is ... oh, I just quit to concentrate on my startup. Getting older, don't sleep as much. Fifteen?
Desktop, at least 2 hours a day. I feel if I am not at the desktop I am not being productive, but 2+ hours daily productivity is great.<p>Laptop/tablet/phone/etc. Looking for inspiration, browsing, stuff like that. I would say sometimes more time may be spent here, but it probably is also 2 hours.<p>TV I try to avoid. I like to watch a few teams and catch some games here and there. Mostly movie time, so another solid 2 hours in this category.<p>6-8 hours easily, and I always feel like I could double this and still wake up the next morning with a full checklist of things to accomplish.
