Compound Microscope: light microscope that has two converging lens systems: the objective and the eyepiece.

Farsightedness: a reduced ability to focus on near objects caused by loss of elasticity of the crystalline lens after age 45.

Camera: equipment for taking photographs (usually consisting of a lightproof box with a lens at one end and light-sensitive film at the other).
