Cataracts generally lead to 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 mild vision changes.
Other symptoms may include:
- Frequent changes in eyeglass prescription
Diagnosis & Tests
A standard eye exam and slit lamp examination are used to diagnose cataracts. Other diagnostic tests are rarely needed.
