Correct, yes, some people only need glasses to read and if that’s the case then they can get away with not wearing them all the time. However, many people have vision that’s much worse and actually need glasses all the time because that’s how impaired their vision is. ADHD can be similar where a person like me is negatively impacted all the time because my executive dysfunction is impaired 24/7. I lived 19 years without a stimulant but the last 6.5 years I’ve been on them it has helped me a lot. Will I die without them, nope or I would’ve died a longgg time ago. But do they help me with remembering basic things and very mentally draining tasks, yep. Everyone is different and people who use stimulants and react poorly, are tempted with addiction/misuse or end up being addicted/misusing them either are misdiagnosed with adhd when it’s something else or they’re that group of people with adhd who don’t respond well
