From stores to street corners the convex mirror has a variety of uses
The word convex means to curve outwards. So when light comes into contact with a convex mirror or surface, the light is spread out, making these types of mirrors exceptionally useful for a number of safety and security reasons.
Convex mirrors are often placed on store ceilings allowing the store manager or security to view a large area of the store at once. These mirrors act as both a preventative measure, stopping would be shop lifters from stealing, and help security personnel spot those that do.
The problem with ATMs is that the person withdrawing money often has his/her back exposed while they are concentrating on their transaction. By placing convex mirrors in a suitable place, the person withdrawing cash can keep an eye on what is going on behind them, allowing them to react in time, should someone suspicious appear.
On roads, bends or driveway entrances
The most useful aspect of convex mirrors is they allow you to see round corners and bends. This makes them particularly useful for blind corners, sharp bends, and your driveway, if you can’t see the oncoming traffic. By placing these mirrors at a suitable height, they allow you to see vehicles coming, when you can’t see them with the naked eye. This means that instead of exiting your driveway inch by inch, more in hope than anything else, you can now see whether the road is clear before exiting.
