Appreciate everyone's comments, without doing the stats it looks like the newer types of varifocal lenses may be a huge improvement on lenses from five years ago, I'm going to test drive a couple of different brands and in the spirit of the forum let you know how I get along, on a similar note my BIL who had corrective eye surgery 15 years ago is now back wearing specs something I'd been considering, so for me at least I'll be sticking with contacts and specs.
