A cataract is a clouding of the eye's natural lens, which is located behind the iris and pupil. This lens is responsible for focusing light onto the retina, allowing us to see clearly. With a cataract, the lens becomes opaque, leading to blurred or distorted vision, difficulty with glare, and sometimes even colors appearing faded. Cataracts typically develop slowly and can affect one or both eyes. They are most commonly associated with aging, but other factors, such as genetics, certain medical conditions, medications, and even prolonged exposure to ultraviolet light, can also contribute to their formation.
While cataracts are generally a part of the aging process, they can be treated effectively through surgical intervention. The surgery involves removing the cloudy lens and often replacing it with an artificial intraocular lens, allowing for improved vision. Most patients experience significant improvement in their sight following surgery, and it is considered one of the most common and safest procedures performed worldwide. If you're experiencing symptoms of cataracts or are concerned about your vision, it's essential to consult an eye care professional for proper evaluation and personalized treatment options.
