Have you heard of 55 yr old eyes improving in vision?

I went to the eye doctor on friday because I felt I couldn’t see clearly with my glasses and very poorly with my contacts. And it had been 4 years since a checkup. My prescription is weaker than it’s been in 10 years! I am searching the house for an old, old pair of glasses to take to his office to check. I have never heard of nearsighted vision improving. I’m going in tomorrow for the trial contacts.
