Causes and Symptoms

Most Cataracts are Age Related

Your chances of getting cataracts increase with age. In fact, almost everyone will develop them if they live long enough.


Other causes include:

  • Injury—a severe blow or deep cut to the eye
  • Birth defect—abnormal conditions in the eyes of unborn babies
  • Harmful factors—disease, radiation, toxic chemicals, certain medications and too much exposure to ultraviolet light

Symptoms include:

  • Blurry, cloudy or distorted vision
  • Loss of contrast
  • Vision slowly but steadily getting worse
  • Need for stronger reading light
  • Problems with glare from bright lights
  • Difficulty driving at night
  • Colors seem faded or yellowish
  • Frequent changes in eyeglass prescription

Your family optometrist will typically discover developing cataracts in the course of a routine eye exam. As soon as they begin causing visual difficulties, your doctor will usually recommend surgery.
