My optician in the UK, maybe Americans are different!

"As you continue to age, presbyopia becomes more advanced. You may notice that you need to change your eyeglass or contact lens prescriptions more frequently than you used to. Around age 60, these changes in near vision should stop, and prescription changes should occur less frequently."
