What are the uses of concave and convex lenses?

Answer:
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.
