A cataract is a clouding of the lens in the eye. This clouding affects vision. A cataract can happen in one or both eyes, but does not spread from one eye to the other. Most cataracts happen as the result of aging, and they are very common in older people. Cataracts affect vision by creating a cloudy area on the lens of the eye. This cloudy area can get larger over time and cause serious vision problems. The lens helps to focus light on the retina, the light-sensitive tissue at the back of the eye. In a normal eye, light passes through a clear lens to the retina, which turns it into nerve signals that are passed to the brain. The lens must be clear for the retina to receive a sharp image. If the lens is cloudy from a cataract, the image that the brain receives will be blurred. Age-related cataracts can also cause discoloration of the lens. Over time, the clear lens slowly changes to a yellowish or brownish color, which tints vision. This gradual change in tint does not make vision blurry.

  • Cloudy or blurry vision
  • Colors appear faded
  • Glare - Headlights, lamps, or sunlight might appear too bright. Lights might appear with a halo around them
  • Problems with night vision
  • Double vision or seeing multiple images in one eye - This symptom might go away as the cataract gets larger
  • Frequent changes eyeglasses or contacts prescription – A person with cataracts might need a new prescription as often as every few months
