The correction of spherical ametropia with lenses worn in front of the eyes dates from the 14th century. Historically, we can consult the classic treatises on optical instruments, such as von Rohr’s (1921). Contact lenses, although their principle was stated in the 17th century, for technical reasons have been used only for the last few decades.
