Cataract: Symptoms, Causes & Treatment

What Is Cataract?

Cataract is a common eye condition that occurs when the natural lens of the eye becomes cloudy over time. This leads to blurred vision and difficulty performing daily activities such as reading or driving. If left untreated, cataracts can significantly affect quality of life.

Cataracts are one of the leading causes of vision impairment worldwide, especially among older adults. Early diagnosis helps in choosing the right treatment at the right time.
