During a patient's assessment, what is crucial to inquire about regarding their visual symptoms?

Inquiring about the duration and onset of visual symptoms is crucial because this information helps to determine the nature and urgency of the condition. Understanding when the symptoms began can provide insight into whether they are acute (newly appeared) or chronic (long-standing), which can significantly influence potential diagnoses and treatment plans. The duration informs the clinician about the progression of symptoms, whether they are worsening, stable, or episodic. Additionally, certain conditions have specific timelines for onset that can aid in differential diagnosis, making it essential to establish this information during an assessment.

Other factors such as family history of eye diseases, previous eye treatments, and screen time may also be relevant, but they do not pinpoint the immediacy or nature of visual symptoms as effectively as understanding their duration and onset.
