Hi...Friends !!
CONVEX LENS :
A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.
WORK OF CONVEX LENS :
Most high quality cameras, telescopes and binoculars use concave lenses to improve the quality of the images they provide. Microscopes and reflecting telescopes make use of a concave mirror, a plane mirror, and a convex lens, while refracting telescopes use two convex lenses.
CONCAVE LENS :
Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.

Uses of Convex Lenses
1.Uses in spectacles to correct the defect of vision called hypermetropia or long sightedness
2.Used for making a simple camera
3.Used as magnifying glasses
4.Used in microscopes, telescopes, film projectors, etc.
Uses of Concave Lenses
1.Concave lenses are used for correcting myopia or short-sightedness.
2.Concave lenses are used on flashlights to magnify the light produced by the bulb.
3.Used in peepholes of house doors for security to provide a view of people or objects outside the doors.
