There was someone at the Kinder Trial on Saturday with a pair of cut down reading glasses - these orienteering glasses I think. I don't wear glasses other than for close-up things like reading, and really struggle with mapreading and running (individually and together!). I've heard of people wearing different contact lenses in each eye, but I don't wear contact lenses or have very good vision in my left eye, so that wouldn't help me.
Has anyone tried orienteering glasses? How do you manage wearing them and seeing the ground to run?
