Maintaining good eye health is essential not only for the comfort and wellbeing of workers but also for sustaining productivity and safety in the workplace. This article looks at protecting eyes from common workplace hazards such as excessive screen time, dry air conditions and environmental particulates.
Understanding the risks
Digital eye strain from screens
The prevalence of digital devices in the workplace has led to an increase in visual complaints, known as digital eye strain. Symptoms are temporary and include tired eyes, dryness, irritation and difficulty focusing, all of which can be exacerbated by prolonged screen uses. For example, staring at screens for long periods can lead to a reduced rate of blinking (blinking helps to replenish the tear film across the eye). This might be worse if having to look up at a screen that is inappropriately high. Using screens is not associated with permanent damage to eyes or eyesight.
The impact of air conditioning on eye moisture
Air conditioning systems can help maintain a comfortable work environment but can also contribute to lower humidity levels. This can lead to dry eyes by increasing tear evaporation, which may then result in irritation and even blurring of vision.
Exposure to airborne irritants
Dust, pollen and other airborne particles can provoke allergic reactions and/or irritate the eyes, potentially leading to reduced visual clarity and discomfort.
Protective Strategies
- Managing screen exposure
To prevent digital eye strain, encourage the implementation of regular screen breaks using the 20-20-20 rule (look at an object 20 feet away, every 20 minutes, for 20 seconds). - Ergonomic workplace design
The position of monitors should be arranged to reduce reflections and glare and ensure they are at an appropriate distance and height. Most modern screens have an in-built anti-glare finish. Comfortable chairs at an appropriate height for workers’ build promote good posture and can also help in preventing strain on the eyes. - Optimising workplace lighting
Employers should ensure that work areas are well-lit, with the level of natural or artificial lighting adequate and appropriate for all tasks to be performed at the workstation. Sharp contrast, reflections, glare and shadows should be minimised. Local task lighting can be provided where necessary to facilitate detailed work. - Controlling indoor humidity
Installing humidifiers in air-conditioned spaces can help to maintain adequate humidity levels and prevent related dry eyes. It is also helpful for employees to stay hydrated by drinking water throughout the day. - Personal Protective Equipment (PPE)
Eye protection may be required in working environments with high levels of particulate matter, such as safety glasses or goggles – appropriate to the task. - Maintaining clean work environments
Regular cleaning protocols should be established to keep workspaces and equipment, like keyboards and screens, free from dust and debris. Good personal hygiene practices, including handwashing, should also be encouraged to reduce the risk of eye infections. - Incorporating Rest and Movement
Frequent breaks to reduce eye strain should be part of the work schedule. Encouraging employees to take short walks and engage in stretching exercises can reduce eye fatigue and is also likely to promote overall physical health.
By recognising potential work-related eye hazards and implementing proportionate measures to control exposure to them, employers can foster a work environment that supports eye health and enhances employee wellbeing.
