Mollweide projection - The Mollweide projection is a non-geometric map projection used for geographic maps of the world, also known as the Babinet projection, or elliptical projection. As its more explicit moniker Mollweide equal area projection indicates it sacrifices fidelity to angle and shape in favor of accurate depiction of area.

Progressive lenses - Progressive lenses, also called progressive addition lenses, progressive power lenses, and varifocal lenses, are eyeglass lenses used to correct presbyopia and other disorders of accommodation. A gradient of increasing lens power is added to the correction for the other refraction error, going from nothing at the top of the lens to maximum magnification at the bottom of the lens.

Plate carrée projection - The plate carrée projection or geographic projection or equirectangular projection, is a very simple map projection that has been in use since the earliest days of spherical cartography. The name is from the French for "flat and square".
