Vision problems associated with cataracts generally move towards decreased vision, even in daylight. Most people with cataracts have similar changes in both eyes, although one eye may be worse than the other. Many people with this condition have only slight visual changes.

Other symptoms may include:

Signs and tests:

A standard eye exam and slit lamp examination are used to diagnose cataracts. Other diagnostic tests are rarely needed.
