If you have a cataract, that doesn’t always mean you need surgery. You may not even notice any change in your vision. Some people who have this condition see just fine if they wear prescription glasses, use a magnifying lens, or rely on brighter lighting.
But as cataracts grow, they can cause more symptoms. You could have dim or blurred vision. You may also have double vision when you look at things through the eye with the cataract. These problems can make it hard to read, work on a computer, and do anything else that calls for clear eyesight.
You may have poor night vision and find it harder to drive when it’s dark. You may be sensitive to glare from headlights. People with advanced cataracts can even fail the vision part of a driver’s test.
