Is it worth keeping a backup pair of glasses for an elderly parent?
I've been thinking about getting a second pair of prescription glasses for my dad just to keep around as a backup. He relies on his glasses every day and if his main pair broke or got lost we'd be kind of screwed until we could get another pair made.
For those of you caring for an older parent who wears glasses full time, do you keep an extra pair around? I'm wondering if it's better to get a more affordable second pair with the same prescription or just wait until there's actually a reason to replace the main ones.
