I wear contacts, just for orienteering, and they work very well, but I only have a high magnification (2.5) in my left eye - if I have a high magnification in both eyes the ground and the distance are blurred and it is most unsettling. They are "single use" ones, "1 day acuvue moist". I had the ordinary ones first, but found they dried out and were difficult to remove.
Fixing the eyesight with the contacts is the easier bit..unfortunately it's the R/G piece which is the challenge with no real solution.
One lense for reading and one for distance worn all the time and refreshed on a monthly basis isn't perfect but works well enough for me..saves faffing with glasses at all. Anything is now a compromise.
Like Gaz I use single use contacts for orienteering. Started last year after various rain/glasses disasters and much nagging from Ann (she was correct, I should have tried ages ago). Mine claim to be variable power (+1.75 to +0.5 I think). It took a little time to get use to the idea, but I now couldn't orienteer properly without them.
