A cataract is a clouding of the eye lens. The lens is the opening where light passes through the eye. It is normally clear and focuses what you see onto the retina (back of the eye). With cataracts, the cloudy lens makes it hard for light to pass through. This causes problems with correctly focusing what you see on the retina. Your vision may be cloudy, hazy, and blurred. You may develop a cataract in one or both eyes.


Follow up with your healthcare provider as directed:

Write down your questions so you remember to ask them during your visits.

Protect your eyes:

  • Wear sunglasses: This will help protect your eyes from the sunlight and prevent eye discomfort.

  • Do not smoke: If you smoke, it is never too late to quit. You are more likely to have heart disease, lung disease, cancer, and other health problems if you smoke. You will improve your health and the health of those around you if you quit. If you smoke, ask for information about how to stop.

Contact your primary healthcare provider if:

  • You have a fever.

  • You have chills, a cough, or feel weak and achy.

  • You have questions or concerns about your condition or care.

Return to the emergency department if:

  • You suddenly lose your eyesight.

  • You feel a sudden, sharp pain in your eye.
