Bifocal Meaning in Bengali: দ্বিদৃষ্টি সংক্রান্ত (noun, /bɑɪˈfoʊkəl/)

Definition and Origin of Bifocal

Bifocal is a noun that refers to a type of eyeglasses or contact lenses that have two different optical powers. The upper part of the lens is used for distance vision, while the lower part is used for near vision. This design allows individuals with both nearsightedness and presbyopia to see clearly at different distances without needing to switch between multiple pairs of glasses. The term “bifocal” originated from the Latin words “bi” meaning two and “focus” meaning point of convergence.

The concept of bifocal lenses was first introduced by Benjamin Franklin in the 18th century. As a renowned polymath, Franklin invented various practical devices, including the bifocal glasses. He needed glasses for both distance and near vision, and instead of carrying two pairs, he decided to merge them into a single pair by cutting the lenses and combining them. This innovation revolutionized the eyewear industry and provided a convenient solution for individuals with different visual needs.
