- A concave lens is a lens that possesses at least one surface that curves inwards. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia). The writings of Pliny the Elder (23-79) makes mention of what is arguably the earliest use of a corrective lens. According to Pliny, Emperor Nero was said to watch gladiatorial games using an emerald, presumably concave shaped to correct for myopia.
A concave lens diverges light rays that pass through it, causing them to spread out. This type of lens is thinner at the center than at the edges. Concave lenses are commonly used to correct myopia (nearsightedness) by helping to focus the light rays onto the retina.
