Lens - A lens is a device for either concentrating or diverging light, usually formed from a piece of shaped glass. Analogous devices used with other types of electromagnetic radiation are also called lense. Used Studio Color 575 M. s: for instance, a microwave lens can be made from paraffin wax.
The earliest records of lenses date to Ancient Greece, with Aristophanes' play The Clouds (424 . Used Studio Color 575 M.

Lux - The lux (symbol: lx) is the SI derived unit of illuminance or illumination. It is equal to one lumen per square metre.
The difference between the lux and the lumen is that the lux takes i.
