Which of the following is a common symptom reported by patients during an eye exam?

Headaches are a commonly reported symptom by patients during an eye exam. This often indicates potential vision issues such as refractive errors (like nearsightedness or farsightedness), eye strain, or poor visual habits, which can all lead to discomfort and headaches. Patients may also experience headaches due to excessive screen time or improper lighting while reading or working.

In contrast, symptoms such as a stiff neck may arise from posture or physical strain unrelated to visual function. Frequent urination typically does not correlate with eye health and might indicate other health conditions, such as diabetes. Skin rashes are also generally unrelated to ocular symptoms and would pertain to dermatological issues. Hence, headaches stand out as a direct symptom that can link to visual problems, making it the most relevant symptom to note during an eye examination.
