Sometimes I'll go years between appointments and my glasses will get old so I'll get a new pair at the local drug store for $13. I just pick out which ever pair makes me see the best.
Is that a good idea?
Yes I'm kidding but that's how allot of the people I know take care of their eye sight.

Although "drugstore readers" might do "in a pinch" you are really short changing yourself if you self prescribe these all the time. Most people tend to pick ones that are way too strong and, besides that, the quality of the lenses is usually quite poor. Also, the optical centres of the readers are set at an arbitrary distance, typically 55mm, which often does not match that of the person wearing these. This will result in significant "induced prism" which means that your eyes may have to converge or diverge excessively while reading, which will add up to greater eyestrain.
As far as your last comment, yah I hear that alot and it is very unfortunate....I could go on and on on that topic!
BTW, DonDavis I sincerely apologize for hijacking your thread!
