I (nearsighted) wear glasses that are quite old at this point, I think ~7 years? My prescription has certainly changed since then, and I have had new glasses made a couple times, but the new glasses always make my eyes feel uncomfortable, despite improving my vision. I try them for a couple days and then give up and return to my 7-year-old glasses. It's been a while, so I don't remember my true prescription, nor the prescription associated with my 7-year-old glasses.
