Cataracts are a common eye condition that affects millions of people worldwide. The development of cataracts involves the clouding of the eyes lens, which hinders clear vision. Although primarily an age-related issue, cataracts may develop in younger people as well.
The lens of the eye is essential for focusing light properly onto the retina, resulting in sharp vision. Cataracts form when the lens becomes clouded, obstructing the passage of light. Common symptoms include blurry vision, poor night vision, sensitivity to bright light, and dull color perception.
Aging is the primary factor contributing to cataract development, though other causes exist. Other causes include diabetes, prolonged exposure to ultraviolet light, smoking, and certain medications. Genetic predisposition and past eye injuries can also increase the likelihood of developing cataracts.
An ophthalmologist can diagnose cataracts through a detailed eye examination. Tests may include checking visual acuity, examining the lens with a slit lamp, and dilating the pupils to inspect the retina. Early detection is crucial for managing symptoms and preventing further vision loss.
The severity of cataracts determines the available treatment options. Enhanced eyewear and lighting adjustments may suffice in the initial stages. For severe cases, surgical removal of the cataract is the best solution. Cataract surgery entails the removal of the clouded lens and its replacement with a synthetic lens.
