Concave lenses make objects look smaller when they are placed close to the lens, while convex lenses make objects look smaller when they are placed far from the lens. This effect is due to the way light rays are refracted by the different lens shapes, causing the image to appear reduced in size.
A concave lens diverges light rays that pass through it, causing them to spread out. This spreading out of light results in the image appearing smaller when it reaches the eye. This is why objects viewed through a concave lens appear smaller than when viewed with the naked eye.
A magnifying lens or magnifying glass is used to make objects appear larger when viewed through it.
A magnifying lens, also known as a convex lens, can make objects look bigger by bending light rays to converge at a point, creating a larger image. This type of lens is commonly used in magnifying glasses, microscopes, and telescopes to achieve magnification.
Because of it's shape a concave lens bends or refracts light outward away from the center of the lens and towards its thicker edges. The light rays never cross or meet a focal point so the image never inverts. A concave lens makes objects appear smaller than they really are.

Make the light divere
Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)

A concave lens is a curved glass that can make objects appear closer than they actually are by diverging light rays that enter it. This type of lens is thinner at the center than at the edges.

Each concave lens bends light to make the object appear larger

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)
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.
