Cataracts are a common eye condition that causes clouding of the eye’s natural lens, leading to blurred or dim vision. Most cataracts develop slowly with age and may not affect vision initially. However, over time, they can interfere with daily activities like reading or driving, especially at night.

What Causes Cataracts?

Cataracts are primarily caused by aging, as proteins in the lens break down and clump together. Other contributing factors include:

  • Diabetes

  • Excessive exposure to sunlight (UV rays)

  • Smoking

  • Alcohol consumption

  • Eye injuries or surgeries

  • Prolonged use of corticosteroid medications
     

How to Treat Cataracts

In the early stages, stronger lighting and updated eyeglasses may help. However, when vision loss begins to interfere with daily life, cataract surgery is the most effective treatment. It involves replacing the cloudy lens with a clear, artificial one (intraocular lens or IOL). Cataract surgery is safe, widely performed, and has a high success rate in restoring vision.

Prevention Tips

While cataracts can't always be prevented, you can lower your risk by:

  • Wearing UV-protective sunglasses

  • Eating a diet rich in antioxidants (leafy greens, fruits)

  • Avoiding smoking and limiting alcohol

  • Managing health conditions like diabetes
