A clinician guide to the diagnosis and remediation of VDT related vision problems

It is expected that by the year 1990 that at least 40 million workers will be using video display terminals (VDT\u27s) in the workplace. There are also 1 million VDT\u27s already in schools and that number is likely to increase. With this increase in VDT usage it appears likely that visual symptoms associated with them will also increase. We as optometrists have an opportunity to provide a special service to our patients in this area but first we must understand the unique properties of VDT\u27s which cause visual symptoms and then prescribe measures to overcome them.
