The human eye is like a camera. Inside your eye, there’s a clear lens that helps you see things clearly, just like the lens in a camera helps take clear pictures. But sometimes, this lens can become cloudy, like a foggy window. This cloudy lens is called a cataract. When you have a cataract, it’s like trying to see through a hazy glass. Things may look blurry, and colors might not seem as bright and vivid as they used to be. It’s a bit like looking through mist or dusty glasses.

Cataracts can make it harder to do everyday things like reading, watching TV, or recognizing faces. Sometimes, bright lights or headlights from cars can bother your eyes more than usual. 

Fortunately, cataracts can be fixed with a simple surgery. The surgeon will replace the cloudy lens with a clear, artificial one called an intraocular lens (IOL), and your vision should improve. There are many choices for what kind of IOL a person can have, and these choices can be discussed with the surgeon before surgery.
