What is the answer to the 'one eye but cannot see' riddle?
The answer is a needle. A sewing needle has a single 'eye' (the hole at the top), it cannot see, and thread is passed through that eye.
Why is a needle the answer to this riddle?
Because the hole at the top of a sewing needle is literally called an 'eye,' yet it has no vision — and you pass thread straight through it to sew.

It's an easy classic riddle, great for kids and family quizzes, but the 'one eye that cannot see' wording still trips up plenty of players at first.
