There are two options for people who need both distance and near vision corrected...multifocal lenses and monovision. Multifocal contact lenses or bifocal contacts are soft, disposable contact lenses which correct distance and near with each eye.They are similar to bifocal glasses because both eyes are corrected for both distances but the design is very different.Monovision means one eye is corrected mainly for distance vision only and the other is corrected mainly for near vision only.ultifocal Contact Lenses Multifocal contact lenses come in many different brands and each is designed a little differently. Soft lenses continuously move and rotate on the eye and when the eye moves so does the lens so the design is not like a traditional bifocal with distance on top and near at the bottom.
