I found out I needed glass when I tried my friend's glasses for fun and saw better with them. Twas very depressing actually, realizing I've seen stuff wrong for so many years. Things is I only have -1, so it's not bad enough to significantly affect daily life, tho it is significant enough in how I experience views. Now when I travel I always have a pair with me for whenever I truly want to enjoy the sight of something. Otherwise I avoid my glasses like the plague.
