What is another word for concave lens?
Pronunciation: [kɒnkˈe͡ɪv lˈɛnz] (IPA) 
A concave lens, also known as a diverging lens, is a type of lens that is thinner at the center than it is at the edges. This lens causes light to spread out, making objects appear smaller and farther away than they actually are. There are several synonyms for concave lens, including negative lens, diverging lens, and scattering lens. Negative lens refers to the fact that the lens diverges light rays instead of converging them like a convex lens. Diverging lens emphasizes the way that the lens causes light to diverge outward, while scattering lens highlights the way that the lens scatters light in different directions. No matter which term is used, the concave lens plays an important role in optics and is a key tool for correcting vision impairments.
