Anecdotally, I had regular eye exams (once every two years) for several years since they were free under insurance, and was prescribed progressively stronger glasses each time. I wound up somewhere around -7.5. For the past ~10 years I’ve just stuck with a single prescription out of sheer laziness + having no optical insurance in the US. Recently, having gotten a proper job with real insurance, I visited an optometrist and was surprised to learn that my prescription had gone down to -7 - and the new glasses really aren’t much different than the old ones visually. A fairly significant part of this is likely due to my eyes not growing anymore (the regular eye exams were during high school + undergrad), but I do like to think that some part of it is not feeling like I always had to update my prescription constantly.
