How often do you replace your glasses for eye health?

I'm curious about people who wear glasses.

Wearing glasses with the wrong prescription despite deteriorating vision seems to be bad for eye health.

But I wonder how much adults, who are not children in their growth stage, prefer to spend on glasses.

I used to change my glasses after about a year, but the ones I am using now are over a year old.

Should I go to an ophthalmologist or an optical shop?

There is hardly any change in vision.
