Even the most well-planned office layouts can pose circumstances that are not ideal for Video Display Terminals (VDT) use. Keep the following checklist in mind when evaluating your workstation:
–Most users prefer a viewing distance of 20 to 26 inches, a little farther away than for reading printed text.
–The computer screen should be placed slightly below eye level. Reference material should be placed on a document holder and moved close enough to the screen so that you don’t have to swing your head back and forth from the material and the screen. If that happens, your muscles can become stiff and sore, and your eyes have to constantly change focus, which can cause eyestrain or headaches.
–Lighting should be modified to eliminate glare and harsh reflections.
