Video Display Terminals, emit UV and ELF radiation and may cause cancer, immune system irregularities, miscarriages and eye fatigue. Computer noise from fans, disk and CD drives is also becoming a source of anxiety, stress and general discomfort . We usually don't realize how loud our computers are: 50dB and more. These problems should be dealt with and add-ons should be provided for present computers to avoid putting us at risks. Some safe screens and quiet power supplies are coming out but they are marginal and prices are prohibitive. Meanwhile the general guidelines for the users are: 1. Position yourself approximately 22 inches to 28 inches (arm's length) from the screen and four feet from the sides and rear of other terminals. 2. Eliminate sources of glare and lower light levels in the room. Don't sit facing a bright window. If necessary, use screen hoods, glare shields over the screen or wear anti-UV/anti-glare glasses. 3. Put a noise absorbing mat under your computer. Pull your computer away from the wall or any hard surface that reflects noise and vibration back to you. 4. Rest occasionally during periods of intense concentration. Closing your eyes helps. 5. Turn off the VDT when not in use.
