They are used mainly for better sight.
Here's an example of each.
Convex is shaped like this ) which gives a wider angle.
They are often used in convenience stores.
Concave are used in side mirrors of vehicles
They both provide different reflections. Much more effective than just a flat mirror for some purposes.

What is the antonym for the word concave lens?
convex lens
Does a microscope use a concave lens or a convex lens?
A microscope typically uses multiple lenses, including both concave and convex lenses, to magnify and focus the light coming from the specimen being observed. The objective lens, which is closer to the specimen, is usually convex, while the eyepiece lens, which is closer to the observer's eye, is usually convex.
What instrument uses a convex concave and a flat lens?
A telescope uses a convex lens to gather and focus light, a concave lens to correct spherical aberration, and a flat mirror to reflect and redirect the light towards an eyepiece or sensor. These components work together to magnify distant objects and allow for detailed observations.
Which optical instrument uses a large concave mirror a plane mirror and a convex lens to gather light focus and enlarge an image?
Astronomical telescopes use a large concave mirror, a plane mirror, and a convex lens in their design. The concave mirror gathers light, the plane mirror reflects it to a more convenient viewing location, and the convex lens magnifies and focuses the image for observation.
Are plano lens convex?
No - by definition. You can have a plano-convex (or -concave) lens (one side flat). Actually a purely plano "lens" would be merely a glass disc.
What are 4 uses for a concave lens and 4 uses for a convex lens?
stupid questions have no answers....
Is a microscope convex or a concave?
A microscope typically uses a convex lens to focus light and magnify an image. The convex lens converges light rays to produce a magnified image, whereas a concave lens would diverge light rays and not be suitable for magnification in a microscope.
Does a movie projector use a concave lens?
No, a movie projector uses a convex lens.
A lens that curves outward is called?
)( is a concave lens() is a convex lens
Which of the following lenses is a converging lens A double-convex lens B spherical-convex lens C plano-concave lens D convexo-concave lens?
Double-convex lens
What kind of lens does a projector use?
projector have concave or convex
List two uses for concave lens?
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
Which type of lens magniies - convex or concave?
A convex lens magnifies.
What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
When does a concave lens act as convex lens?
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .
What is a convex and a concave lens?
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
