Up to 90 percent of all job-related eye injuries can be prevented, when simple safety precautions are followed. Use eye protection whenever there is a chance that machines or activities could present a hazard from flying objects, chemical splashes, radiation or a combination of these or other dangers. Anyone walking through areas of hazard should also wear protective eyewear. 

Although computer screens may cause uncomfortable eyestrain and dry eye symptoms, they don't permanently damage vision. To determine the cause of your discomfort, see your ophthalmologist for a complete eye exam. You may need to wear glasses when working at a computer or your prescription may need updating. In addition, an ergonomic evaluation of your workstation may identify problems that could lead to eyestrain. 

While computer eyestrain may be uncomfortable, construction, automotive repair and manufacturing work can be physically hazardous to your eyes and vision. These occupations have the highest rate of workplace eye injuries. 

Most injuries occur where safety eyewear is not mandated and is left up to the individual. Many of those injured didn't think they needed to wear eye protection or were wearing eyewear inappropriate for the job. Safety glasses that meet industry safety standards are marked with the number "ANSI Z87" on the frames or lenses. Check with your ophthalmologist to learn about the eyewear appropriate for your occupation.
