Your eye is like a camera. There is a lens in the front of your eye that is a lot like the lens on a camera. Light passes through the lens to get to the back of your eye. As you get older, so does the lens in your eye. It starts becoming cloudy and dark, and this is what we call a cataract.
Having cataracts is like looking through a foggy window. Your vision might become blurry, and you may have trouble reading or seeing at night.
You can get cataracts in one eye, or both. Cataracts do not spread from one eye to the other.
Almost everyone gets cataracts as they grow older
You are more likely to get cataracts if you have a history of:
You might have some of the symptoms in the list above, or you might have no symptoms at all if your cataracts are small. When you go to the eye doctor, he can see your cataract by looking through an instrument called the ophthalmoscope, or by looking through the microscope.

You will need cataract surgery to remove your cloudy lens if you can no longer see well enough to do your everyday tasks. You can discuss this with your eye doctor.
