< h2 > Definition of Cataract < /h2 >

< h3 > Introduction < /h3 >

Cataract refers to a common eye condition characterized by the clouding of the natural lens of the eye, which leads to progressive loss of vision. This condition typically develops as a part of the natural aging process, but it can also be caused by injury or certain medical conditions. Early stages of cataracts may cause minimal visual disruptions, but as the condition progresses, it can significantly impair vision and, if left untreated, may ultimately lead to blindness. < /p >

< h3 > Causes and Risk Factors < /h3 >

Cataracts commonly occur due to protein clumping in the lens, causing it to become opaque and cloudy. Aging is the most common risk factor for cataract development, with the majority of individuals over the age of 60 having some degree of cataract formation. Other causes include certain medications, such as corticosteroids, trauma to the eye, exposure to ultraviolet radiation, diabetes, smoking, and genetic predisposition. < /p >

< h3 > Symptoms < /h3 >

Symptoms of cataracts vary depending on the severity of the condition. Initially, individuals may experience blurred or hazy vision, increased sensitivity to glare, difficulty seeing at night, and the need for brighter lighting. As cataracts progress, other symptoms may include double vision in one eye, fading or yellowing of colors, frequent changes in eyeglass prescriptions, and decreased contrast sensitivity. It is important to consult an ophthalmologist if any of these symptoms are experienced to obtain an accurate diagnosis. < /p >

< h3 > Diagnosis and Treatment < /h3 >

Cataracts can be diagnosed through a comprehensive eye examination that includes a visual acuity test, a dilated eye examination, and other tests to evaluate the overall health of the eyes. While early cataracts may be managed with prescription glasses or contact lenses, surgery is the only definitive treatment for advanced cataracts. Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens. This procedure is generally safe and highly effective in improving vision and quality of life for individuals with cataracts. < /p >

< h3 > Conclusion < /h3 >

Cataract is a common age-related eye condition characterized by the clouding of the lens, leading to vision impairment. Prompt diagnosis and appropriate treatment, usually through cataract surgery, can help restore clear vision and improve quality of life for those affected. Regular eye examinations and adopting preventive measures such as protecting the eyes from harmful UV radiation can contribute to maintaining optimal eye health and potentially delaying the onset of cataracts. < /p >
