What Are Cataracts?
Our eyes operate similarly to a camera. Each eye has two natural lenses: the cornea, which is the lens on the surface, and the crystalline lens located within the eye. Together, these lenses focus images onto the retina at the back of the eye. At birth, the crystalline lens is clear, but as we age, it begins to yellow and harden. When it becomes cloudy, this condition is called a cataract and can significantly affect the quality of our vision.
Cataracts are most commonly associated with aging, but they can also be linked to factors such as family history, diabetes, eye injuries, prolonged exposure to sunlight, certain medications, smoking, and previous eye surgeries. They tend to develop gradually, allowing people to adapt to changes in their vision without realizing the extent of the decline. Many individuals do not fully appreciate how much clearer the world appears until after the cataract has been removed.
