Having spent all day at work yesturday in front of a computer i went to zero my rifle and found that I struggled to keep my eyes focused through the scope. I regularly have medicals and eye tests and find that my eye sight is better when I havn't been sat in front of a computer screen for hours beforehand. They do seem to settle after about an hour after i walk away from the computer and have given them a rest.
Maybe I'm just getting old or alternatively I should spend less time at work and more time out stalking. Could also use this as a reason for investing a quality pair of Binos.
