Wearing contact lenses is an alternative option for people who do not want to wear eyeglasses to improve their vision problems caused by presbyopia. This option may not work properly if there are certain conditions related to eyelids, tear ducts or the surfaces of the eyes such as dry eyes. Several lens types to correct presbyopia are available, including:
Bifocal and multifocal contact lenses. Both bifocal and multifocal contact lenses are designed to provide clear vision at all distances for people who have presbyopia. Bifocal contacts lenses have two prescriptions in the same lens whereas multifocal contact lenses have a range of powers (similar to progressive eyeglass lenses) in each lens.
Monovision contact lenses. With monovision contacts, a contact lens for distance vision is worn in one eye (usually dominant eye) and a contact lens for close-up vision is worn in the other eye. With modified monovision, a bifocal or multifocal contact lens is worn in one eye and a contact lens set for distance in the other (usually dominant eye). The patients use both eyes for distance and one eye for reading.
