Question

I have a single eye but cannot see. What am I?

Answer 1

needle is the ans.....

Answer 2

Answer: Needle

Needle has eye at a end through which thread is inserted to sew. Though there are many types of needles, the needle used for sewing is the correct answer.

The needle is a slender metal object which is sharp at the one end and has eye at another end as it is not a living object it can't see. So, the eye referred in the question is not a human eye.
