I remember being able to read the timer on the other end of the subway station(120m) in my city, so in low light conditions at that. The numbers were maybe 20cm in height. In my case it's not even the defect itself, but the associated astigmatism. For a long time I was unaware of the issue because it started in one eye, so the other compensated until it couldn't. Now I get around two weeks of perfect vision upon getting a new glasses prescription and it's back to "normal".
