Headaches are only a symptom of hypermature cataracts, a progressed form of cataracts that have become completely white, according to Medical News Today. At this point, sufferers may also experience inflammation and pain, and the cataracts need to be surgically removed.
The most common form of cataracts is age related. According to Medical News Today, approximately 70 percent of individuals in the United States over the age of 75 suffer severe vision impairment caused by cataracts. Other risk factors include a family history of cataracts, diabetes, long-term exposure of the eyes to bright light, previous eye injuries and lead exposure.
Medical News Today lists common symptoms of cataracts as clouded vision, spots or white patches in the field of vision, decreased vision in poor light, difficulty reading and difficulty seeing in bright light. People with cataracts must change glasses frequently, and the effectiveness of glasses gradually begins to decrease. Some sufferers see halos around bright lights and double vision in rare cases.
Medical News Today adds that cataracts are generally diagnosed by an ophthalmologist or optometrist. Although surgery may be necessary in advanced cases, sufferers can deal with earlier symptoms by keeping glasses prescriptions up to date, using a magnifying glass for reading, placing brighter lights in the house and avoiding night driving.
