I found I need readers so much that varies were the best bet. Saved having to wear the damn things around my neck.
I don't actually need readers at all at the moment. I only have problems with very small print (eg. legal small print or small streets on an A to Z or in an index). Reading books or a Kindle in bed or a laptop screen is no problem. However I can't do any close up with my distance glasses. I have to take them off, even when chatting to a friend over a meal or coffee. In an evening class, I need the glasses to listen to the tutor but not o read from a book in front of me.
I have gone ahead and ordered 1 pair. I have longer to try them out than I was told yesterday. The sales person yesterday said 2 to 4 weeks but an older (and I think more senior) guy today said 'up to 3 months'. I could then exchange for single lens if I wanted to and/or buy a 2nd pair as single lens or varifocal. The price for the 2nd pair isn't affected by my choice of type.
