Diopter relates to the refractive or light-bending capability as well as the curvature of a lens. The higher the diopter of a lens the closer an object must be to the lens to be in focus. This refers to the diopter’s focal length.

Disinfectants are used on hard, inanimate objects to kill infectious fungi or bacteria but not necessarily their spores.Disinfectants are divided into two major types: "hospital" and "general use".
