Low Vision Services in Whitehall, PA
Patients diagnosed with low vision are those whose vision cannot be treated by ordinary methods. Their sight is often not correctable by eyeglasses, contacts, medicine or surgery. This means that routine activities and daily living can be challenging. At Vision Masters our low vision specialist, Dr. Dana Mignogna, helps her patients to live independently. With her assistance many of her patients are able to return to work, stay independent and live happy productive lives.
What Is Low Vision?
Low vision is a term used in the optical industry to describe when a patient's vision is unable to be corrected by traditional methods. This includes vision impairments, legal blindness and almost total blindness. These impairments can include blind spots, tunnel vision, visual field defects, or the reduced ability to distinguish colors and/or contrasts. The goal in low vision is to improve functional vision by aiding independence in daily life with devices.
Causes of Low Vision
Low vision is most common in older patients but can affect those at any age. Low vision issues can result from eye injury, hereditary, brain injuries, birth defects, and eye diseases. There is help available if you have vision loss due to macular degeneration, glaucoma, diabetes, stroke, cataracts, retinitis pigmentosis, etc.
