Causes and Diagnoses of a Cataract

The main cause of cataracts is aging. Other factors that put you at risk of developing a cataract include: 

  • Genetic predisposition
  • Diabetes and other metabolic diseases

  • Trauma to the eye
  • Previous eye surgery
  • Excessive exposure to sunlight
  • Living at high altitude
  • Chronic eye inflammation

Diagnosing cataracts 

Your eye care physician can diagnose a cataract during a routine eye exam that includes:

  • Visual acuity test: This common eye chart test measures vision ability at various distances using a series of lenses.
  • Pupil dilation: The pupil is widened with eye drops to allow a close-up examination of the eye's lens and retina.
