How often does the patient report their eyes itching?

The patient reports constant itching in their eyes, indicating a persistent symptom that can be associated with various conditions such as allergies, dry eyes, or chronic irritants. Constant itching suggests that the issue is ongoing and not limited to specific times or triggers, reflecting a more serious or chronic concern that may require further investigation or treatment. This symptom can greatly affect the patient's quality of life, prompting a thorough examination and possibly lifestyle adjustments or medication to alleviate discomfort.

In contrast, the other options imply either infrequent irritation, specific timing, or exposure to certain environmental factors, which do not convey the urgency or severity that constant symptoms suggest. Understanding the nature of eye itching is crucial in diagnosing underlying causes such as allergic responses, infections, or other ocular conditions.
