KOMPAS.com – Convex mirror is a type of spherical mirror whose shape is inflated outwards, like a mountain. Convex mirrors are often used to aid human activities in daily life.
What is an example of use convex mirror? The following is the benefits of convex mirrors in everyday life!
Sunglasses
Sunglasses are made of convex mirrors. So, sunglasses can reflect most of the sunlight that hits the surface.
Glasses plus
In addition to sunglasses, convex lenses are also used as plus glasses. The use of a convex mirror helps people with hypermetropia who cannot see close objects.

Magnifying glass
Another example of the benefits of a convex mirror is a magnifying glass. Convex mirror and concave mirror combined can form a magnifying glass and help humans to see small things.
Parking lot mirror
In the upper corner of the parking lot, usually a large convex mirror is found. Convex mirrors in parking lots are useful to provide a broad view for motorists. So, you can park your vehicle easily.
Vehicle mirrors
The benefits of convex mirrors in daily life The most frequently encountered is the vehicle mirror. Vehicles such as cars, motorcycles, trucks, and other motorized vehicles use mirrors made of convex mirrors.
Reported from Physics LibreTexts, a convex mirror produces an extended image shape between the focal point and the mirror. Thus, producing a smaller shadow of an object as well as a wider view for motorists.
Street description
Another example of the benefits of convex mirrors in everyday life is street lighting. One of the principles of street lighting that is often used is specular reflection. The principle of specular reflection uses a light reflector in the form of a convex mirror.
Convex mirrors are used because of their ability to scatter light rays over a large area. Thus, street lighting is more energy efficient and does not create glare that endangers road users.

Keratometer
Keratometer is an eye examination tool which is an example of the use of a convex mirror in everyday life. Reported from Lumen Learningthe keratometer considers the cornea of our eye like a convex mirror and measures the curvature of the cornea.
Corneal curvature is measured by finding the focal length of the cornea. This is usually done to find the right contact lens.
Camera lens
Convex mirror-shaped lenses are also used in cameras. Cameras with convex lenses allow for wide and focused shots.
Microscope
Apart from being used in cameras, convex lenses are also used in microscopes. A convex lens magnifies the image, allowing the microscope to magnify objects and observe very small objects.
Supervisor glass
Convex mirrors are also used as surveillance glass in stores, shopping malls, and other places. The convex mirror reflects a wide shadow, so it gives a picture of a large area to monitor the situation.
