"Cat's eye" is the common name of the door mirror, which is generally installed on the iron door of the home. When someone knocks on the door, the people in the house can see the outside through the door mirror, which is very clear when looking inside the house through the door mirror, but when looking inside the house from the outside, it becomes very blurry. So it allows people in the house to distinguish whether the people outside are acquaintances or robbers.
