I've been using varifocals for about three years now and although they take a while for you to train yourself how to use them, they have been great. My advice - don't skimp on the optician and lens cost. Also, chose frameless. The frameless advice is from a fellow 'Magoo' and helps with peripheral vision. Also, when learning how to use them, you will find them different and it takes a while for your brain how to process the image. While you are learning - do not go back to your regular glasses- Once you have the new varifocals, there's no reversion mode!
Of course, it all depends on your prescription. In my case, my close up vision is OK, but my accommodation (ability to change focus) was getting poorer as my eye's lenses hardened with age. I am also astigmatic.
BTW - if you are prescribed with bi/varifocals in New Zealand, you are grounded for 3 months while you get used to them.
