Being a diabetic, I'm supposed to get my eyes checked every year regardless of whether my prescription has changed. Diabetics run the risk of getting something like a mini stroke in the eye's blood vessels, and can lead to blindness if not treated. So I usually go at least for an eye exam, and possibly get new glasses if need be. Which is exactly what I'll be doing this weekend... Not only for my yearly exam, but also because my dog loves to wrestle with me and swiping my glasses off. So now my current set has a few repair issues to deal with (and I'll probably just get a new pair).
