I was replying to the person who needs new glasses because of unstable vision and strictly from a financial perspective.
I know it's common for adults to change vision but usually once a year is a frequency more seen in children and teens. At least from my experience talking to people and being in an ophthalmologist chair since infancy. I was a frequent flyer at the ophthalmologist's office as a child (once a month was common for a while) and I had lots of questions.
EDIT: I haven't actually heard a lot about the elderly so I don't know their typical frequency of vision change. The only data point I have is a 60 year old I knew who got LASIK and was back in glasses in about 2 years.
On an unrelated note, I went to the same ophthalmologist for 20 years and it was eerie how it never changed. The ophthalmologist always looked the same, he always had the same staff and they looked the same, and the office didn't change. After a while it was like stepping into a time machine when I went there.
