Normal vs yellowed vision
  Your vision can be dulled or yellowed from cataracts.

Blurring or dimming vision
  Blurry or dim vision is a symptom of cataracts.

Distorted vision
  If you have cataracts, you may experience distortion or ghost images in your vision.

Cataract symptom progression

Gradually, as cataracts progress, you may have symptoms such as:

  • Painless cloudy, blurry or dim vision
  • More difficulty seeing at night or in low light
  • Sensitivity to light and glare
  • Seeing halos around lights
  • Faded or yellowed colors
  • The need for brighter light for reading and other activities
  • Frequent changes in eyeglass or contact lens prescription
  • Double vision within one eye

The only way to know for certain if you have cataracts is to have a dilated eye exam (where your pupil is widened with eye drops). Your ophthalmologist can detect early signs of cataract development by looking at your eye's lens.

Get a baseline exam at age 40 when early signs of disease and changes in vision may start to occur. Your ophthalmologist (Eye M.D.)  will let you know how often you should return for follow-up exams. At any point, if you have symptoms or risks for eye disease, see your Eye M.D. Because your risk for cataracts and other eye diseases increases as you get older, starting at age 65 you should see your Eye M.D. every year. A complete eye examination will rule out any other condition that may be causing blurred vision or eye problems. Early detection and treatment of cataracts is critical to preserving sight.
