Which of the following is NOT generally considered a symptom of eye strain?

Neck pain is typically not classified as a direct symptom of eye strain. Eye strain, often caused by prolonged use of digital devices or reading, primarily affects the eyes and can lead to discomfort in the eyes themselves. Symptoms commonly associated with eye strain include dry eyes, where a lack of sufficient moisture leads to discomfort; eye redness, resulting from irritation and fatigue; and sensitivity to light, which occurs when the eyes become more sensitive due to overuse. Although neck pain may be experienced by individuals who have eye strain—possibly as a secondary effect from poor posture during extended screen time—it is not a direct symptom of the condition itself. Thus, neck pain stands out from the other options, which are specifically related to the strain experienced by the eyes.
