At what age did you start needing reading glasses?

How did you first start noticing that you needed reading glasses? And did glasses from 99 cent store work until it got worse? I am in my 30s so I am getting nervous about it.

I am 23 and don't need reading glasses . But my father started using reading glasses few years ago (about 45). He could not see the small texts on newspaper . It is also impossible for him to thread a needle. And often get frequent headaches, eyestrain or eye fatigue while reading. I don't have shopping experience from 99 cent store and unable to know the quality of their glasses . Generally glasses can still work without any big problems unless your prescription change .
