I was initially intrigued by this thread because I thought it said "MANWOMAN"!!! (Purely morbid curiousity). Oh stop it Mr. Pie!
Try doing a search for posts by Magoo. He has some pretty sensible sounding advice. If you need glasses to drive safely, then sure, get some glasses. It's even harder to get a Class 1 if you're pancaked against a brick wagon or serving a stretch at the Royal Hotel for mincing a toddler. Just don't fall into the usual trap of starting to use them for close up work, or anything other than driving/flying for that matter. They DO f*** your eyes up, and that's why opticians will be more than willing to sell you a pair or two - That's how they make a living!!!
