The most prevalent complaint among computer users is eye strain (Doctor Smith). When people use computers for extended periods of time, they frequently experience symptoms such as eye fatigue, discomfort, and impaired vision (NYSUT). Other adverse effects include hurting, fatigue, burning, and watery eyes. The severity of these problems varies depending on how often users abuse computers and what type of work they do. Computer users should take special care not to overuse their eyes. This can happen when people spend too much time viewing screens from near distance or in artificial light. If you feel like you're spending too much time staring at a screen, stand up and move around every 20 minutes or so. This will help prevent eyestrain and other health problems related to doing computer work. People who work with computers need to know how to protect themselves against harm caused by digital equipment. Computer users should learn basic safety rules to avoid injury or damage to personal property. For example: only use power tools with caution to prevent accidents; don't run extension cords across floors or open books on desks to prevent fires; and keep cell phones off the table while eating to prevent spills. Computers can be a great tool for productivity and business efficiency, but they can also be harmful if used improperly or without caution. It's important that users understand their needs and avoid overusing their eyes or other body parts.
