Cataracts are a clouding of the natural lens in your eye. When you have cataracts, it’s difficult for light to enter your eye, which causes blurred vision that may make you feel like you’re looking out a foggy window.1

Cataracts happen naturally as you get older.
They develop gradually, like dirt slowly building up on a car windshield 2. At first you may not notice any changes to your vision, but eventually you will start to notice symptoms.1

The only way to treat cataracts is through surgery, during which the natural lens that has been affected by cataracts is removed and replaced with a syn­thetic lens, called an intraocular lens or IOL.




When you have cataracts, objects may appear to have halos around them. You may also notice glare around streetlights and traffic lights, making it hard to drive at night.3
