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.

∙ 13y agoA concave lens can be used for magnifying glasses and glasses to correct nearsightedness.
EDIT: Magnifying glasses use convex lenses, as those lenses ENLARGE objects.

What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
What are the tpyes of lens that bulges outward?
A lense which bulges outwards is a convex lense.Additionally, a lense which bulges in is called a concave lense. You can remember the difference by thinking about the fact that a cave is like an inward bulge in a cliff, and the inward-bulging lenses are concave.
What does bi-concave mean?
Concave means that there is a dip in the object, like it has caved in. Bi-concave means that it is dipped in on two sides of the object. A good example is a red blood cell. It is a bi-concave disk - it has dips on two sides of it.
What two factors determine the type of image formed by lens?
The focal length of the lens and the distance between the lens and the object.
List two uses for a member of each representative group?
Been looking for the same answer myself....
What are the two example uses of concave lens?
a peep hole, such as you'd find in the door of a hotel room, uses a concave lens to make the image of the person standing in the hallway appear smaller than they actually are.Glasses for nearsighted people.
How are reflecting and retracting telescopes different?
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
What are the two different shapes of a lens?
Convex and concave
What are two basic kinds of lenses?
Two basic kinds of lenses are the concave lens and the convex lens.
Is concave lens thicker than convex lens?
You can't directly compare the two classes of lenses like that.What you can say is:-- The middle of a convex lens is thicker than the edge.-- The middle of a concave lens is thinner than the edge.One way to remember it: The middle of a concave lens is caved in.
What are the uses of a concave lens?
Two uses of concave lenses are: 1. Used to make spectacles for people who cannot see short distance objects. 2. Used in peep hole to make the image of the person standing in the hallway appear smaller.
What has two lenses called the eyepiece lens and objective lens?
Maybe its "ocular".
Difference between convex and concave lens?
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
What are two possibilities for an image formed by an convex lens?
a convex lens is thicker in the center then at the edges. A convex lens acts like a concave mirror, because it focuses rays of light.

What is the difference between convex and concave lenses?
The expressions relate to the shape of the surfaces of the lens. Concave means that the surface is like the inside of a sphere, convex means that it looks like the outside surface of a sphere. A lens has two surfaces. Most often the spectacle lens are bent away from the eye: the nearer surface is concave and the outside surface is convex.
