Copy holder Copy holders are recommended for individuals who perform input tasks from a source document. Copy holders eliminate frequent neck movements caused from looking back and forth between screen and paper, as well as continuous refocusing of the eyes. To maximize the benefits of a copy holder, it should be at the same height as the monitor, and as close to the monitor as possible. Lighting The recommended luminance at a VDT task area where data entry and retrieval is performed exclusively is 750 lux. These lighting levels can be adjusted for personal preference and may be augmented by task lighting.
Glare is the main lighting concern when working with VDTs.
Remove or cover shiny surfaces and objects. Use blinds or curtains to minimize window glare. Install diffusers on overhead fluorescent lights. Adjust the angle of the monitor, so that the screen is vertical. Use incandescent task lights over source documents.
