The word plano has two distinct origins depending on the context in which it is used.
1. In relation to geography, plano comes from the Latin word planus, meaning flat or level. This etymology describes the geographical meaning of the word, typically used to refer to flat or open plains.
2. In the context of eyewear, such as prescription glasses, plano derives from the Latin word planus as well, but with a different meaning. In this case, it refers to lenses that have no optical power or prescription. Plano lenses are used in eyeglasses when vision correction is not required, but the lenses are used for protective or fashion purposes.
In both cases, the etymology of plano traces back to Latin and its root word planus.
