Bifocal contact lenses were invented by Otto Wichterle in 1967 and are designed to correct both nearsightedness and farsightedness in a single lens. These contact lenses have a unique aspheric design that allows for the simultaneous correction of both refractive errors. Bifocal contact lenses are a popular choice for people who have both near and far distance vision problems and are also a good option for people who dont want to wear glasses.
