It's up to you
If you are still a BB (student)
I don't want to be "four eyes"
It's best to go outdoors more often
If you are a migrant worker (adult)
Then it depends on whether you can create or not
Don't stay up late, don't die, don't fight
The focus of "outdoor activities" is not on "activities" but on "outdoors"
That is, as long as you're outdoors
Even if you don't do anything
It can also prevent myopia

Nature, a leading medical journal, described the researchers' findings: "It was actually an afterthought, and we asked some questions about sports and outdoor activities [for children who are not nearsighted]"
The occurrence of myopia in adolescents is often a process from emmetropia to pseudomyopia, and then to true myopia.
The main remedies for pseudomyopia are to increase the amount of time spent outdoors during the day (2 hours a day), reduce the use of electronic devices, correct poor eye habits, and use dilated eye drops to relax the eyes if necessary.

If it develops to "true myopia", the "remedial" method needs to go through some additional myopia interventions (using myopia prevention and control glasses, OK lenses, etc. under the guidance of a doctor) to avoid myopia progressing too quickly.
