What does the concave lens do?
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.

The writings of Pliny the Elder (23-79) makes mention of what is arguably the earliest use of a corrective lens.
