You only look at things relatively close to you from 9 to 5? You don't have computers or TVs at home? A smartphone? Cooking instructions?

It's not a hyperbole, glasses are massively inconvenient to those of us handicapped without, and having to hot-swap then depending on subject is massively more inconvenient.

It's hyperbole because you consistently ignore the fact that eyes can change focus for the short term, that's like the one thing they do. It's straining your eyes for long periods, at the same focal point, such as while working, that we need to help with.

PS: you are right, maybe instead of only at the desk, just wear a "near sight" pair all the time, when you're indoor, and a far sight pair when you are out. Point is you dont have to hot swap.

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".
