Cataracts

WHAT YOU NEED TO KNOW:

What are cataracts?

A cataract is a clouding of the eye lens. The lens works with the cornea to bend light as it passes through to the retina. It is normally clear. A cloudy lens makes it hard for light to pass through. Your vision may be cloudy, hazy, and blurred. You may develop a cataract in one or both eyes.


What increases my risk for cataracts?

  • Age 65 years or older
  • A medical condition such as diabetes, low blood calcium, or high blood pressure
  • Your eyes being exposed to sunlight or x-rays
  • Long-term steroid use
  • Alcohol use, or smoking cigarettes
  • Family history of cataracts

What are the signs and symptoms of cataracts?

  • Increasing loss of vision sharpness
  • Cloudy, foggy, fuzzy, or hazy blurring of vision
  • A halo appears around lights
  • Headlights and sun may seem very bright
  • Double vision
  • Colors appear faded
  • Loss of vision

How are cataracts diagnosed?

Your healthcare provider may notice a cloudy appearance when looking at your eyes. He or she may also do any of the following:

  • A visual acuity test is used to check your vision, eye pressure, and eye movements.
  • Ophthalmoscopy is used to see the back of your eyes. Eyedrops may be used to dilate your pupils.
  • A slit-lamp test is used to look into your eye with a microscope with a strong light.

How are cataracts treated?

You may need a different prescription for your glasses in the early stages of cataracts. Cataract lens removal surgery is a very common surgery. Your lens will be removed and replaced with an artificial lens.

How can I protect my eyes?

  • Wear sunglasses to protect your eyes from the sunlight and prevent eye discomfort. Make sure the sunglasses have UV protection.
  • Do not smoke. Cigarette smoking increases your risk for cataracts. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.

When should I seek immediate care?

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

When should I contact my healthcare provider?

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