Understanding Cataracts: A Brief Overview of Eye Health
Cataracts, a prevalent eye condition, affect millions worldwide, causing a gradual decline in vision. Typically associated with aging, cataracts result from the clouding of the eye's natural lens. This cloudiness occurs as proteins in the lens break down and clump together over time. While age is a primary factor, genetic predisposition, medical conditions like diabetes, and prolonged exposure to UV radiation can contribute.
Symptoms of cataracts include blurred vision, sensitivity to light, difficulty seeing at night, and faded colors. Early diagnosis through regular eye exams is crucial for timely intervention. Cataract surgery, a common and safe outpatient procedure, involves replacing the cloudy lens with an artificial intraocular lens (IOL).
Preventive measures include wearing UV-protective sunglasses, maintaining a healthy diet rich in antioxidants, and avoiding smoking. By understanding cataracts and their risk factors, individuals can make informed decisions for preserving their eye health.
