A monocle is a type of eyeglass that only has one lens. It is often used as a fashion accessory or for people who only need to correct the vision in one eye. Monocles are not commonly worn nowadays, but they can be seen in period dramas or movies set in the past. If you hear or read the word 'monocle', it is most likely referring to this type of eyeglass.
