Together with the China National Institute of Standardization (CNIS), SGS has developed a certification scheme to help the consumer electronics industry address market demands and consumer concerns over visual fatigue for electronic devices.
The low visual fatigue certification will be known as the Weighted Visual Fatigue (WVF) index and is based on “applicable international standards, general industrial specifications and accumulated data,” SGS said in a statement.
Products certified through WVF will be evaluated to assess the level of visual fatigue they cause users.
The certification assessment process involves objective optical testing of displays, simulating human visual perception for blue light and flicker evaluation, alongside human factor testing that uses volunteers to assess brain activity, eye movement and visual function via electroencephalogram (EEG) and Critical Flicker Frequency (CFF) tests.
Jeff Zhao, general manager of the connectivity & products of SGS-CSTC, said: "We are delighted to launch this innovative certification service, combining objective testing with subjective experience, to comprehensively evaluate the level of eye fatigue that a person will experience when using a display screen.
"Through this collaboration we hope to guide the industry in developing and promoting products which offer consumers a safer and healthier user experience."
The new certification has already been awarded to Huawei, who became the first organization to adopt the certification when its MateView SE monitor was awarded certification earlier this summer.
The MateView SE is the first Huawei monitor to have the eBook Mode, a display that create a paper-like reading and editing effect. Its WVF index is 3.142, “meaning that the product causes a very low level of visual fatigue after 40-minutes of use,” SGS said.
