Cataracts develop slowly and can affect vision over time. Recognizing the early symptoms is important because timely cataract diagnosis can help prevent severe vision problems. One of the most common early signs is blurry or cloudy vision, which makes it difficult to read, drive, or recognize faces clearly. People may also notice increased sensitivity to light, glare from headlights at night, faded colors, and frequent changes in eyeglass prescriptions.

If these symptoms appear, an eye specialist will recommend several cataract eye tests to confirm the condition. Many patients wonder how is cataract diagnosed during an eye examination. Doctors usually perform a detailed cataract diagnosis procedure that includes vision testing and a careful examination of the eye lens.

One of the most important tools used in diagnosis is a slit lamp for cataracts, which allows the doctor to closely examine the structures of the eye. Early detection through proper testing helps doctors monitor the condition and recommend the right treatment at the appropriate time.
