A cataract is a clouding of the lens in the eye that affects vision. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car, especially at night. Most cataracts develop slowly and don’t disturb your eyesight early on. It is commonly seen in older people because cataracts will eventually interfere with the vision overtime.

Causes of cataracts- the cloud lenses
Mostly, cataracts develop when aging or injury changes the tissue that makes up your eye’s lens. Some cataracts are because of inherited genetic disorders that may lead to other health conditions and increase your risk of cataracts. Cataracts may also be result of various eye conditions, medical conditions like diabetes, trauma or previous eye surgery. Long term use of steroid medications may also contribute to cataracts.

Diagnoses of cataracts- the cloud lenses
Cataract is diagnosed through a comprehensive eye examination that includes:

  • Visual acuity test: This eye chart test measures how well you see at various distances.
  • Dilated eye exam: Drops are placed in your eyes to widen the pupils. Your ophthalmologist uses a magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems.
  • Tonometry: Numbing drops may be applied to your eye to check the pressure inside the eye.
