Video display terminals, commonly known as VDTs, are electronic devices that display visual information from a computer or other electronic device. They are commonly used in offices, homes, and other settings where people need to interact with computers for extended periods of time. VDTs typically consist of a cathode ray tube (CRT) or liquid crystal display (LCD) screen, a keyboard, and a mouse or other input device. The use of VDTs has become increasingly common in recent years due to the widespread adoption of computers and other electronic devices. However, concerns have been raised about the potential health effects of prolonged VDT use, including eye strain, headaches, and neck and back pain. To address these concerns, many manufacturers have developed VDTs with features designed to reduce eye strain and other health problems, such as anti-glare screens and adjustable brightness levels. Despite these concerns, VDTs remain an essential tool for many people in a wide range of industries, including business, education, and healthcare. They are used for a variety of tasks, including word processing, data entry, and graphic design. As technology continues to evolve, it is likely that VDTs will continue to play an important role in our daily lives.
