Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia). Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia). A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look bigger. A concave mirror can magnify. Convex mirrors always shrinks things. They are used sometimes in offside rear vision mirrors for vehicles. A concave mirror will also shrink things if you look at the mirror from far enough away and the object you look at is also far away (but you wouldn't want to use it for a rear vision mirror because it then also turns stuff upside down). Concave lenses disperse light rays outward, rendering it impossible for them to focus incoming light onto a plane surface. Their "focus" is virtual, behind the lens on the side of the light source. If the concave surface is used as a reflector, it will form a real image. This is the basis for reflector telescopes. Further info: http://en.wikipedia.org/wiki/Lens_(optics)
What else can I help you with?
A type of lens that magnifies an object?
convex converging apex... :P
Is magnifying lens a convex or a concave lens?
A magnifying lens is typically a convex lens. This type of lens is thicker in the center than at the edges, causing light rays to converge in a way that magnifies objects when viewed through the lens.
How are concave lens and convex lens different?
Concave lenses are thinner in the middle and thicker at the edges, causing light rays passing through them to diverge. This type of lens is used to correct nearsightedness or myopia. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through them to converge. These lenses are used to correct farsightedness or hyperopia.
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 is a type of lens that magnifies an object?
A convex lens is a type of lens that can magnify an object. This lens is thicker in the middle and thinner at the edges, causing light rays to converge and create a magnified image.
Which type of lens magniies - convex or concave?
A convex lens magnifies.

What type of lens does the watch repairer use is it convex or concave?
Convex Lens
What is the only type of image that can be formed by both a concave lens and a convex lens?
Virtual image

What type of glass lenses are fatter in the middle than at the edges called?
Convex lens are thicker in the middle. Concave lens are thinner in the middle.
What is a type of lens that magnifies an object?
A convex lens is a type of lens that can magnify an object. This lens is thicker in the middle and thinner at the edges, causing light rays to converge and create a magnified image.
What is a type of lens that magnifies and object?
A convex lens can magnify an object by converging light rays to a focal point, producing a larger image.
What is convexo-concave lens?
A convexo-concave lens is a lens that has one side convex (outward bulging) and the other side concave (inward curving). This type of lens can be used to correct myopia (nearsightedness) by diverging light rays entering the eye.
What are two type of lenses?
convex and concave
