Our eyes are not well suited to staring at a computer screen. The eye cannot lock focus on the pixels or tiny dots that make up computer screens. A computer user must continually focus and refocus to keep the images sharp. This process results in repetitive stress of the eye muscles. Additionally, after prolonged computer use, the frequency of blinking is decreased and eyes dry out and become sore. As a result, the ability to focus diminishes and vision may blur resulting in headaches. Because of the elevated gaze, computer users frequently dip their heads which results in poor posture and neck pain. |
