Final answer:
Ergonomic standards suggest positioning the monitor screen about an arm's length away, approximately 20 to 30 inches (50 to 76 cm) from the user's face, and at or slightly below eye level.
Step-by-step explanation:
According to ergonomic standards, the monitor screen should generally be positioned about an arm's length away from your face, which is roughly 20 to 30 inches or about 50 to 76 centimeters for most people. This distance helps to reduce eye strain and allows you to comfortably view the entire screen without too much head movement. The top of the screen should be at or slightly below eye level.
Moreover, individuals who have myopia, or nearsightedness, may need to adjust this distance based on their far point. For example, a myopic person who can see objects clearly only up to 20 cm away may need corrective lenses to see the monitor properly at the recommended distance.
As the near point tends to increase with age, some older people may also need to adjust the distance of the monitor to ensure clear vision.This is approximately 50-70 centimeters or 20-28 inches. This distance helps in reducing eye strain, neck and back pain, and allows for comfortable viewing of the screen.
