Fluorescent Lighting Usually, general-purpose fluorescent lighting is not the best choice for computer environments. It is usually installed with excessive illumination levels, and its light is well diffused, which promotes screen glare. This does not mean that all fluorescent lighting is unsuitable. There is some evidence that full spectrum causes less glare and is more pleasing to the average eye. The grid or lens in a florescent fixture has a great deal of influence on glare properties.
Parabolic diffusers are perhaps best of all, although more expensive.
They minimize lateral glare. Nearly everyone wants a window near his or her desk. Natural light, however, diffusing through a window, is a powerful glare source. Try to locate the VDT to minimize glare. Windows near VDT's should have opaque blinds, and screens should be turned away from the window.
