I was probably very young to do this. Perhaps one the youngest to do this for convenience. But I was 48 and within 2 years my presbyopia prescription went from 0 to 2.5. It would probably stop there. But I felt too crippled not to be able to read how much things cost in grocery store, what crap would Craft foods put in their chocolate etc.
So I went for it.
Have NO 0 NO 0 regrets.
It was challenging at first but then - freedom. Real happy now. Especially when my 50+- old friends are hunting for glasses at parties :-)
