Safety Convex Mirrors

A Convex Mirror is a spherical reflecting surface (or any reflecting surface fashioned into a portion of a sphere) in which its bulging side faces the source of light. Automobile enthusiasts often call it a fish eye mirror while other physics texts refer to it as a diverging mirror.
A Convex Mirror is also a good security device. Store owners, for instance, install a number of them inside their stores and orient them in such a way that a single security personnel can see large portions of the store even while monitoring from a single location. They are the large disk-like reflective surfaces that you see near the ceilings of grocery or convenience shops.
Uses of Convex Mirror
Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings.
They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is a lack of visibility.
They are also used in some automated teller machines as a handy security feature that allow user to see what all is happening behind them.
They are used in passenger side mirror on a car and somewhere it is labelled as “objects in mirror are closer than they appear” to warn the driver.
