If you're over 60 the eye test is free.
If you're on Job Seekers Allowance, the glasses are free.
Provided, of course, that you pick basic frames and single vision lenses. Mind you, my new glasses are only costing me £4 for basic Varifocals, which I need 'cos that's what I've been using for the past 10 years.
I bought one of those strings for hanging your glasses round your neck, because I keep losing mine - I take them off to read or use the computer, and never put them down in the same place twice running. As a result, I sometimes have to spend half an hour searching the house to find them. However, I am definitely only going to do that in the house - don't want to be seen out with the glasses hanging round my neck - makes me look old.
Problem is, I've lost the string...
