Learn about FiltersPrivacy Do you ever have confidential information or other sensitive material on your computer monitor that you don’t want others to see? If you do, then you need a privacy filter. 3M™ Privacy Filters make on-screen data visible only to persons directly in front of the monitor. This not only helps reduce the stress and inconvenience associated with trying to conceal these sensitive materials, but can also improve productivity by allowing you to continue working with confidential information, even when others are nearby. Eyestrain and Fatigue Glare is a common cause of eyestrain among computer or Video Display Terminal (VDT) users. Glare can be caused directly from light shining in your eyes or indirectly from reflections on computer monitors and other surfaces. According to a survey of the American Optometric Association (A.O.A.), almost 10 million people a year suffer from VDT-related eyestrain and physical symptoms of discomfort. And it's estimated that as many as 75% of all VDT users may suffer some eyestrain symptoms. Those figures may even be low because many people mistakenly attribute the burning eyes and headaches they experience to allergies or lack of sleep. What’s more, glare can also cause discomfort and reduce productivity by causing workers to sit in awkward positions in order to see the screen. And many users mistakenly assume that the back, neck and shoulder pain they suffer are solely the result of poor posture or poorly designed chairs. Radiation The electrical components of computer monitors generate various types of electromagnetic radiation. Very high frequency (VHF) radiation is emitted in minute quantities that experts conclude pose no known risk to health. However, low frequency radiation (ELF/VLF) is also emitted in small quantities. Studies are inconclusive, but the effects most often linked with long-term exposure to ELF/VLF radiation include miscarriages and childhood leukemia. 3M™ Privacy Filters, with the anti-radiation feature, help monitors meet radiation guidelines and standards by blocking 99.9%of the electric field (E-field) ELF/VLF. Why testing anti-glare computer filters to a recognized international standard is important. Many manufacturers of anti-glare computer filters do not use recognized test methods to support their optical performance claims for transmission, contrast and reflection reduction. It is confusing and misleading to the end user. One of the best ways to test anti-glare computer filters is to the same measurement criteria used to test an actual computer monitor. After all, an anti-glare filter does become part of the monitor once they are installed. It only makes sense - and good science – to test them the same way. The use of the ISO 9241 display ergonomic standard as the benchmark testing protocol for anti-glare computer filters means for the first time the end user will know that the anti-glare computer filter they are buying is tested to the highest publicly accepted standards in display ergonomic testing. By using the internationally recognized ISO 9241 standard for electronic displays and an independent testing agency, filter manufacturers can prove the optical performance of their filters using the test methods of accepted international standards. This demonstrates a commitment to provide the best quality, highest performing products and the ability to back it up with independent testing to an accepted international standard. 3M™ Executive Computer Filters have ISO testing and to date are the only computer filters with proven optical performance as tested by independent testing laboratory TUV Rhineland GmBH. Tips for Reduced Glare There are many ways that computer users can reduce screen glare and related eyestrain:
