broadcasting system, have shown that the glass, marketed as Ultraguard in the UK, can significantly reduce glare and subsequent eyestrain for operators, enhance contrast, and can cut out 99% p e r cent of ultraviolet radiation. Ultraguard is already in wide use on VDU screens in offices throughout the UK, where the glass is manufactured in sizes that are easily clipped on to established monitors. Rankim Glass, the manufacturer, produces the glass to order for larger projects. The glass has already b e e n fully tested by the National Radiological Protection Board and the Scientific and Industrial Research Association.
