Cataracts are eye conditions that cause cloudy vision, making it hard to see clearly. People with cataracts may notice that objects appear blurry, colors are less vibrant, and vision at night is more challenging.

The most effective treatment is surgery, where the cloudy lens is replaced with a clear artificial one.
