Key Difference: Concave and convex are two basic types of lenses. A convex lens focuses light rays, whereas a concave lens causes the light rays to diverge.
A lens can be defined as a transparent material (like a glass) that has either an open curved surface or one flat surface or two curved surfaces. They work on the principles of refraction, as they change the direction of light waves by refraction. A convex lens focuses light rays, and therefore is also known as a converging lens. The focal point is the point where the light rays meet.
These types of lenses are thicker in the middle than in comparison to their edges. Due to this structure, it is able to converge the light rays. They produce real images, and therefore are mainly used in various optical instruments. A convex lens enables a thing to look bigger than its actual size. It happens due the fact that rays focus on the object and the object looks bigger than its actual size. Light that passes through a convex lens can be focused on a surface like a screen.
A concave lens is just the opposite of a convex lens. It is thinner in the middle and thicker at the edges. Therefore, it diverges the light rays. The emerging rays do not actually intersect. However, they seem to intersect on the incidence side by tracing the emerging rays backward

Answer:
Light microscope, telescope, magnifying glass, and overhead projector with convex lenses
Camera lenses, eyeglasses, and a flash light all have concave lenses
Explanation:
- Convex lenses are sometimes known as converging lenses because the rays converge after passing through them.
- A diverging lens is so named because the rays diverge after passing through the concave lens.
- Light microscopes and telescopes use convex lenses and mirrors to magnify images of very small or distant objects.
- In a camera, a convex lens is used to create a reduced image of an object.
