What is the experience of nearsighted people going out without glasses?

I have been nearsighted since the sixth grade of primary school. I could only sit in the first three rows and look at the blackboard. I only wore glasses in high school, and the mathematical formulas on the blackboard were all fuzzy, even if I sat in the second row. Finally, I wore glasses. From now on, I will not wear glasses unless I watch the blackboard, computer or TV, because I am afraid my glasses will be deformed. The advantage is that if you look at the shape of my eyes, you won't feel deep myopia. It is important to wear glasses when going out, otherwise you can't see the name of the station clearly. I also learned a skill to identify people by clothes and shapes, and I have strong adaptability in poor light.
