NIOSH Supplemental Rest Breaks Minimize Eye Strain For Data Entry Workers

Breaks during day help eyestrain ...

"A new study by a team of scientists from the National Institute for Occupational Safety and Health (NIOSH) finds that workers who are allowed several short breaks during the day suffer less from the side effects of eyestrain than workers who are allowed standard breaks twice per day. The researchers were following up and expanding on previous research conducted in 2000, which demonstrate that frequent rest breaks minimize eye strain and discomfort among data-entry employees without negatively affecting their productivity.

Researchers from NIOSH followed 51 workers for 8 weeks. The workers received standard work breaks (two breaks per day, 15 minutes each) for half of the study and an additional four, 5-minute breaks each day for the other half.

After asking study participants about the levels of eye strain and discomfort they experienced during the the entire portion of the study, researchers found that:

Participants’ ratings of discomfort and eyestrain were significantly lower with supplemental breaks. The supplementary breaks also attenuated the accumulation of discomfort during work sessions.

Data-entry speed was significantly faster with supplementary breaks, so that work output was maintained even though 20 minutes of work were replaced by the supplementary breaks over the work day."    (Continued via Occupational Hazards)    [Ergonomics Resources]

Data entry is not "work"... it's slavery

Ergonomists should fight against the use and banalization of these terms! Accepting them is accepting the unacceptable conditions that people have to transit today in order to be payed : data entry's not a work, it's just replacing with humans the machines companies cannot design, buy, rent or maintain. And the problem isn't solved with rests...
