Which statement about screen-time posture is recommended?

• A. The screen should be angled at 45 degrees relative to your line of sight.
• B. The screen should be perpendicular to windows with eyes lined up to the top one-third of the screen.
• C. The screen should be placed behind you so you can lean back.
• D. The screen should be as close as possible to your face.

Answer: (B)

Positioning the screen to minimize glare and align your gaze for a neutral neck posture is the key idea. Placing the screen perpendicular to windows helps prevent reflections that force you to squint or lean awkwardly, which reduces eye and neck strain over long sessions. Having your eyes line up with the top third of the screen means you’re looking slightly downward, not straight ahead or upward, which keeps the neck in a more natural, relaxed position and reduces extension or flexion.

Other setups tend to promote uncomfortable postures: angling the screen away from a direct line of sight can require awkward head tilts; placing the screen behind you invites leaning back or twisting to see it; and placing it too close can cause eye strain from cramped focus.
