This significantly underestimates the eye strain from using the wrong glasses or no glasses. "Long periods" is minutes in my case.

And yes, most will just use short-range glasses all day as their only pair, which is exactly the thing you insisted that you did not understand ("I dont understand why people especially shortsighted people still use the same glasses for everything. Why don't octometrists know better?").

Sometimes it might make sense to just ask those with the handicap rather than make baseless assumptions about their situation as an "outsider".
