Visual display units, commonly referred to as VDUs, are electronic devices that display visual information from a computer or other electronic device. These devices are commonly used in offices, homes, and other settings where computer work is performed. VDUs come in a variety of sizes and types, including cathode ray tube (CRT) monitors, liquid crystal display (LCD) monitors, and organic light-emitting diode (OLED) monitors. The use of VDUs has become increasingly common in recent years, as computers have become an essential part of daily life for many people. However, prolonged use of VDUs can cause eye strain, headaches, and other health problems. To address these concerns, manufacturers have developed VDUs with features such as anti-glare screens, adjustable brightness levels, and ergonomic designs that minimize strain on the eyes and neck. VDUs have revolutionized the way we work and communicate, allowing us to access vast amounts of information and connect with people around the world. However, it is important to use these devices responsibly and take steps to minimize the health risks associated with prolonged use.
