Contact Lenses

Contact lenses are medical devices that have the potential to provide great vision, comfort, safety and convenience. When fitted casually, and worn improperly with little or no aftercare, they can be harmful to the eye. At Dr. Aller’s optometry office in San Bruno, CA, we will teach you how to properly care for your lenses, so that you can enjoy your lenses for years to come. We carefully examine the eyes of contact lens patients to determine the best type of contact lens for that individual. We use lenses from all over the world in an effort to craft the healthiest, most comfortable, lens that will give you the best vision. Contact lenses can be prescribed for Myopia, Hyperopia, Astigmatism, Presbyopia, Dry Eye, Binocular Vision Disorders, Myopia Reduction (Corneal Refractive Therapy or Orthokeratology), and to control the progression of Myopia.
