And no, you shouldn't look at the back of it. :)
Whenever I talk to anyone about looking at the computer monitor for a longer period of time everyone thinks i'm nuts when i say i can look at it for 12 hours straight with no problem at all.
After that statement I get the usual dose of: "You're such a geek!", "Sure way to ruin your eyesight!" and "Don't you have a life?" replies.
Just to set things straight: "Yes I'm a geek with a touch of Nerd and proud of it!", "Not really.", "Yes I do have a life. It just gets put on hold sometimes." :)
I then ask people how exactly are they looking at their monitor?
And i get this description for a reply:
Isn't that a nice picture? Just look how that head smiles. Bet you it won't be smiling after 8 hours of that kind of looking!
Then i go on explaining how you should be looking:
See now this head will keep smiling even after 8+ hours!
The key here is that when you're looking straight you should see the top of your monitor. Then tilt it a bit upwards like shown on the picture.
This way you have to look down to the monitor.
Looking down means your eyelids can keep the top half of your eye closed, which means half of your eye muscles are relaxed,
which means only half of your eye is drying out, which means longer optimal operation at the same cost.
ROI (Return on Investment) on this is like 10.000.000.000.000.000.000 % (10 trillion). :))
If you're reading this blog then your eyes are your most precious resource.
Keep them relaxed!
