A lens is a transmissive optical device that affects the focus of a light beam through refraction. A simple lens consists of a single piece of material, while a compound lens consists of several simple lenses, usually along a common axis.
OYEAH provides lenses with wide range of size and materials and the lenses types shown as the table:
