A cataract is a clouding of the lens in the eye which leads to a decrease in vision. Cataracts often develop slowly and can affect one or both eyes.

Causes

  • Age : Age is the most common cause. Lens proteins denature and degrade over time, and this process is accelerated by diseases such as diabetes mellitus and hypertension
  • Trauma
  • Radiation : Ultraviolet light, specifically UVB, has been shown to cause cataracts
  • Genetics
  • Skin diseases : The skin and the lens have the same embryological origin and so can be affected by similar diseases. Those with atopic dermatitis and eczema occasionally develop shield ulcers cataracts.
  • Smoking and alcohol
  • Inadequate vitamin C
  • Medications : Some medications, such as inhaled corticosteroids
  • Post-operative

Classification

Cataracts may be
– partial or complete,
– stationary or progressive, or
– hard or soft.
The main types of age-related cataracts are nuclear sclerosis, cortical, and posterior subcapsular

Signs & Symptoms

  • Reduction of vision.
  • Glare as their major symptoms

The severity of cataract formation, assuming no other eye disease is present, is judged primarily by a visual acuity test.

Prevention
