Why did franz schubert sleep with his glasses on?

Franz Schubert is often humorously said to have slept with his glasses on due to his nearsightedness, which made it difficult for him to see clearly without them, even in low light. This anecdote reflects his dedication to his craft, as he would often work late into the night, ready to compose or jot down musical ideas at a moment's notice. While it's likely more of a legend than a confirmed fact, it underscores Schubert's intense focus on his music.
