Understanding Your Contact Lens Prescription #5 - Add Power
Bifocal contact lenses usually contain a prescription for reading or other close-up viewing. The add power is expressed in diopters (a unit for refractive power of lenses). Even if the plus sign is not written on the prescription, it is assumed. For further information or to book a contact lens appointment with one of our doctors please call any of our three Rochester, NY Cornerstone Eye Associates locations in Gates (585-328-0153), Brighton (585-244-2200) or Irondequoit (585-266-7880).
