Presbyopia is a vision condition in which the eye cannot focus on near objects. In most cases, reading glasses or bifocal glasses are prescribed to correct presbyopia. But contact lenses can be prescribed also. Special multifocal contact lenses are available but vision may not be as optimal as eyeglasses. As an alternative, many practitioners prescribe monovision where one eye is fitted with a distance lens and the other with a reading lens. Monovision needs a period of adaption. Reading glasses can be worn over contact lenses for near task.
