A convex lens is a type of lens that is:
- Thin in the center and thicker at the edges
- Curved inward, like a bowl
- Diverging, meaning it spreads out light rays
- Negative in power, meaning it reduces the size of an image
- Used to correct nearsightedness (myopia) in eyeglasses
- Used in optical instruments, such as telescopes and microscopes, to reduce the size of an image
- Characterized by a negative focal length
Convex lenses are also known as diverging lenses, since they diverge light rays away from a single point. They are used in various applications, including optics, photography, and vision correction
