I know what you are all on about, I ignored the fact that the eyesight was going for a few years, then two years ago aged 49 got my eyes tested and started wearing glasses for reading and close up work. Most of the people that know me have a good laugh about it, as I used was working as a TV service tech when I got my glasses, and I had been adjusting the focus on my own TV as it always seamed a bit off. God knows how many TV's belonging to other people I adjsted the focus on incorrectly before I got the glasses.
