bi-focals vs cheaters

One other point, if you do decide to try polarised bi-focals, or similar
stuff, then either try to get a cheap pair loaned to you "on spec" from your
optician, get cheap lenses fitted to existing frames, or buy a cheap pair.
If you can not get away with them, then this can otherwise be a very
expensive mistake.

Actually, the same thing applies to bi-focals generally. I know a few
people who just can not bear to wear them, but once you have paid for them
you are stiuck with them.
