When purchasing a VDT
the buyer should consider several characteristics to reduce health compromising effects.
The most common ergonomic VDT
problems deal with placement: sitting too close to the VDT
, placing the VDT
too high or too low, or pushing the VDT
too far to one side of the desk or counter.
Thus, several studies have examined the problem of musculoskeletal discomfort and pain among VDT
users and the factors that affect this discomfort.
Taking advantage of this victory, the phone companies plan to offer these new services over "video dial tone" systems (VDTs
engineers replaced the V-blocks with thin V-elements strung together on two sets of thin metal bands that fit into slots at the sides of the elements.
For instance, this arrangement should allow the worker to sit at least three feet from the front of the VDT
and five feet from the back in order to minimize the radiation-related problems.

* Design freedom: VDT
is a thermoplastic, and as a result, products can be designed with complex geometries and colors, and can be overmolded directly onto rigid plastic substrates without adhesives.
That complaint was more common with prolonged VDT
work (over 4 hours a day) and for persons wearing contact lenses.
January will be 5 years since VDT
premiered their first concert "And so we begin..." Visionary for the 5 years since has seen its students, professional artists, staff, and supporters grow to new heights with grace and love.
Initially research was focused on the ocular effects of radiation hazards, but subsequently came to include symptoms due to exposure of the eyes to video display terminals (VDT
), known as the Video Display Terminal/Computer Vision Syndrome.
