Diverging lens

A diverging lens, also known as a concave lens, spreads light rays outward when they pass through it. This causes the rays to appear as if they originate from a single point behind the lens. As a result, images formed by a diverging lens are usually smaller, upright, and virtual—meaning you can't project them onto a screen. These lenses are commonly used in devices like eyeglasses for nearsightedness, because they help diverge light before it reaches your eyes, allowing you to see distant objects more clearly.
