Understanding Cataracts: Causes, Symptoms, and Treatments
Cataracts are common age-related eye conditions causing clouded vision. This article covers causes, symptoms, and effective treatment options, including surgical procedures that restore vision. Recognizing early signs and understanding risk factors are essential for timely intervention and improved quality of life.

Cataracts are a prevalent eye condition primarily affecting older adults. They occur when the natural lens in the eye becomes cloudy, impairing clear vision. The cloudiness results from protein buildup within the lens, reducing light entry and causing visual distortions. The term "cataract" originates from Greek, meaning a swift flowing stream turning opaque. Most cases develop gradually, making early detection difficult. Annually, millions seek medical help for cataract-related vision issues, especially those over 60, impacting activities like reading, driving, and outdoor pursuits.
Age is a significant factor, but other risk factors include diabetes, smoking, UV exposure, and genetics. Cataracts are classified into three types: subcapsular, cortical, and nuclear, each with distinct features. Initial symptoms may be subtle, such as slight blurriness or glare, but as the condition progresses, vision becomes significantly obstructed. Treatments include corrective eyewear and surgical removal, which provides lasting improvement and restores clarity.
