Found this post extremely useful. As someone who spends many hours looking into a screen, these exercises have definitely educated me into taking action to ensure my eyes stay good for longer.

I had a scare earlier today, from lookin at a 22" widescreen for around 2 hours straight I looked out the window at someone passing by who caught my attention and my eyes couldn't make out their face as it was all blurry where I was looking.

I think it was because my eyes were at the same focus for so long that when I quickly looked at something far away they didnt have time to focus.

Have got booked in for a checkup.
