Answer 1

Does it? My vision has been the same (a slightly myopic -0.75) for 15+ years and I rarely wear glasses or lenses. My girlfriend does wear glasses (her vision is a lot worse, different on each eye and with astigmatism), and it changes to the extent that she needs new glasses every 3 years or so.
