Eye injuries are a frequent and serious occurrence in workplaces across the United States, with an estimated 2,000 workers sustaining job-related eye trauma daily. While these incidents can range from minor irritation to permanent vision loss, experts estimate that nearly 90% of all workplace eye injuries could be prevented with proper safety measures and protective eyewear. The most common eye irritant is often not a single substance but a category of physical hazards present in many industries.
The Leading Cause of Workplace Eye Irritation
The most common cause of acute workplace eye injury is contact with flying or falling objects, dust, and small particles. Data from the U.S. Bureau of Labor Statistics (BLS) indicates that contact with an object or piece of equipment is the leading cause of eye trauma, accounting for about two-thirds of all reported injuries. This category includes foreign bodies striking the eye at high velocity, which can lead to corneal abrasions or more severe penetrating injuries.
Many common industrial activities generate these physical irritants at hazardous speeds, including grinding, sanding, drilling, sawing, and chipping. These tiny fragments of metal, wood, plastic, or concrete can be propelled faster than a hand-thrown object, giving the worker little time to react.
The ubiquity of these mechanical hazards across industries such as construction, manufacturing, and maintenance makes them the top statistical threat. A significant factor contributing to these injuries is the failure to wear appropriate eye protection, or wearing the wrong type of protection for the task. For instance, a common mistake is wearing safety glasses without side shields, which allows particles to enter the eye from the side or around the protective barrier.
Common Chemical and Environmental Hazards
While flying debris causes the highest number of acute injuries, other common workplace irritants include chemical and environmental hazards. Chemicals account for a large portion of the remaining eye injuries, typically resulting from liquid splashes, vapors, or fumes. Exposure to hazardous substances like acids, solvents, degreasers, and industrial cleaning agents can cause immediate and severe irritation or even corrosive injury.
A chemical splash requires immediate attention because corrosive agents can permanently damage the cornea within seconds. Chemical fumes, even those that are nearly undetectable, can also cause irritation, conjunctivitis, or corneal ulcers depending on the material and duration of exposure. Workers in laboratories, maintenance, and janitorial roles are at elevated risk for these types of exposures.
Beyond acute chemical exposure, chronic environmental and ergonomic factors contribute to eye irritation, particularly in office settings. Prolonged use of digital screens can lead to digital eye strain. Symptoms include blurred vision, headaches, and dry eyes, which are exacerbated by reduced blinking rates when focusing intensely on a screen.
Other environmental irritants include dry air from heating, ventilation, and air conditioning (HVAC) systems, as well as glare from improper lighting or windows. These factors do not cause acute trauma but contribute to chronic eye discomfort and fatigue. Additionally, workers exposed to high-intensity light sources, such as welders, are at risk of photokeratitis—an injury similar to a sunburn on the eye—from ultraviolet (UV) or infrared (IR) radiation.
Immediate Steps After Exposure
When an eye exposure occurs, the immediate reaction dictates the severity of the outcome, especially with chemical irritants. If the eye is exposed to a chemical, the affected person must immediately flush the eye with clean water for at least 15 minutes, using an eyewash station, shower, or faucet. The water should flow from the inside corner of the eye outward to avoid contaminating the other eye.
It is important not to rub the eye or attempt to neutralize the chemical with other substances. After the initial flushing period, immediate medical attention is necessary, and the victim should be transported while flushing continues if possible. For non-penetrating foreign bodies, the person should blink repeatedly to see if the eye’s natural tearing can flush out the particle.
If blinking fails, rinsing the eye with water or a sterile eyewash solution can help dislodge the debris. If an object has penetrated the eye surface or is embedded, or if the injury is a result of high-velocity impact, no attempt should be made to remove it. The eye should be protected with a shield, such as the bottom of a paper cup taped over the area, and medical professionals should be contacted immediately.
Ensuring Long-Term Eye Safety
Preventing workplace eye irritation and injury requires a structured approach that prioritizes long-term safety controls over reliance on individual action alone. The most effective preventative measures begin with engineering controls, which involve modifying the work environment to eliminate the hazard at its source. Examples include installing machine guards on equipment that produces flying debris, using local exhaust ventilation to capture chemical fumes, and positioning safety screens to contain sparks.
Administrative controls involve establishing safe work practices and training employees on hazard recognition. This includes mandatory safety training, posting warning signs, and implementing policies like the 20-20-20 rule for office workers to mitigate digital eye strain.
The final layer of defense is Personal Protective Equipment (PPE), which must be correctly selected for the specific hazard. Safety glasses with side shields are suitable for impact hazards, while sealed goggles are necessary for fine dust or chemical splashes. For high-hazard tasks like welding, specialized face shields or helmets are required to guard against both physical debris and harmful radiation.
