Ergonomic problems triggered by computer video display terminal use have been under discussion for years. But one issue often overlooked by those who conduct workstation evaluations is vision. While there is no evidence linking long-term computer use to permanent eye damage, working extensively at a computer may create or intensify visual symptoms and problems.
Imperfect or obstructed vision can lead to ergonomic injuries among computer users, too. Computer users typically place themselves in front of their terminals in order to see their monitor screen, reference material, and keyboard. The posture they assume often is ergonomically incorrect. Health and safety professionals should consider workers' vision when performing workstation evaluations to offset eye strain as well as other ergonomic injuries.
