Why do indians wear a Bindi?

Answer 1

I don't know about the third eye, but we just where it as a fashion item.

Answer 2

It shows the marital status of women and also brings prosperity and happiness to the family. Even men were Bindi but it has nothing to do with their marital status. One of the reason for keeping a Bindi is, it protects the third of a person. When a persons third eye opens it means he/she has attained enlightenment and gets closer to God.
