My wife has been putting off replacing her contact lenses because not only will she need to pay for new contacts, but she'll have to pay for a new eye exam (I've said to go ahead and do it, but I guess she figures she can live with her old contacts a little longer). Can anybody out there explain why she can't just get new contacts with the same prescription without paying someone to say "yup, you need this prescription"?

Sure, her eyes may have changed slightly. But so what? If she's satisfied with how well she can see with her current prescription, how is it anybody else's business to tell her that she can't keep using it? Nobody smashes my glasses every year to force me to get updated lenses -- I decide on my own whether I can see well enough with what I've got, or whether I want an adjustment. (Okay -- that's not 100% true -- when I moved to Nebraska, the local DMV did check to ensure that I can see well enough to drive with my old lenses, which I could, but they're the only one's who've checked.)

Is there some eye health issue here? Even if there is, which would be worse -- continuing to wear a pair of contacts long beyond their intended "expiration" date, or getting a new pair of the same model, even if it's not exactly perfect?

It seems pretty clear that not allowing people to buy contacts with a prescription over a year old is nothing more than the industry's way of squeezing more money out of the consumer. It makes me want to file a class action lawsuit.
