Dry eye, visual comfort, and overall well-being in the office

Workplace Eye Wellness Month highlights eye health in modern work environments, where prolonged screen use and indoor conditions contribute to dry eye disease. Dry eye affects comfort, visual quality, and productivity, and is recognized as a multifactorial condition influenced by environmental, visual, and systemic health factors.^1,2

Lighting, screens, and visual ergonomics

Office lighting plays a critical role in eye comfort. Harsh overhead fluorescent lighting, excessive brightness, and uncontrolled natural light increase glare and visual stress. Improper monitor placement and reflective screens exacerbate eye strain and dryness.³ Positioning monitors perpendicular to windows, using adjustable LED lighting, and controlling light with shades reduces glare. Antiglare screens and appropriate brightness settings support visual comfort.^4,5

Humidity, airflow, and indoor air quality

Low indoor humidity contributes to tear film instability and evaporative dry eye.⁶ Heating, air conditioning, and overhead fans accelerate tear evaporation, particularly when airflow is directed toward the face. Desktop humidifiers and avoiding direct HVAC exposure can improve symptoms. Airborne irritants such as formaldehyde and volatile organic compounds from office furniture and building materials may also contribute to ocular irritation.³

Allergens and environmental irritants

Indoor allergens, including dust and carpet mites, provoke ocular surface inflammation and worsen dry eye symptoms.⁷ Poor ventilation increases exposure to these irritants. Regular maintenance of carpets and upholstery, improved air filtration, eyelid hygiene, and preservative-free artificial tears or saline rinses may help reduce allergen load and improve comfort.⁸

Screen time, blink rate, and tear stability

Prolonged screen use significantly reduces blink rate, leading to tear film instability and increased evaporation.^4,5 This effect is well documented among office workers with computer-based occupations.³ Conscious blinking, frequent breaks, and adherence to the 20-20-20 rule are effective strategies. Positioning monitors slightly below eye level encourages more complete blinking and improved tear distribution.⁴

Incomplete blinking, meibomian function, and productivity

Digital screen use increases incomplete blinking—where eyelids fail to fully close—impairing meibomian gland lipid expression and destabilizing the tear film.^9-11 This accelerates evaporative dry eye and worsens symptoms throughout the workday. Dry eye–related discomfort has been linked to reduced work productivity and increased presenteeism, highlighting the broader workplace impact of untreated ocular surface disease.^12,13

Contact lens wear in the digital workplace

Contact lens wearers are particularly vulnerable to dry eye in office environments. Digital display viewing, combined with contact lens wear, exacerbates tear film instability and intensifies dryness by reducing blink efficiency and increasing evaporation.^14-16 Workplace strategies include limiting continuous lens wear during intensive screen tasks, transitioning to part-time spectacle use, and using lubricating drops as needed.

Vision correction and binocular alignment

Even small uncorrected refractive errors increase accommodative and visual stress, worsening dry eye symptoms.⁵ Regular eye examinations ensure accurate prescriptions. Small phorias or binocular vision imbalances may contribute to eye fatigue and dryness; appropriate management may include prism correction or vision therapy.⁵ Antireflective coatings and computer-specific lenses can further reduce glare and visual discomfort.^4,5

Ocular surface support, sleep, and overall well-being

Topical therapies such as lubricating drops may provide symptomatic relief. Current research identifies TRPM8 (transient receptor potential melastatin 8) channels—cold-sensing receptors on the cornea—as key regulators of blinking and tear secretion.^17,18 Prescription or over-the-counter product TRPM8 activation may represent a novel therapeutic approach for workplace dry eye.¹⁹

Nutritional support is also important. Omega-3 fatty acids (eicosapentaenoic acid [EPA] and docosahexaenoic acid [DHA]) combined with γ-linolenic acid (GLA), an anti-inflammatory omega-6 fatty acid, have demonstrated improved dry eye symptoms and reduced ocular surface inflammation in clinical trials.^20,21 GLA combined with EPA/DHA is more effective than omega-3 alone, as this combination prevents proinflammatory arachidonic acid accumulation while promoting anti-inflammatory pathways.^20,21 Adequate hydration and a balanced diet also contribute to tear quality and ocular surface integrity.

Dry eye disease is increasingly linked to poor sleep quality, fatigue, anxiety, and depressive symptoms, forming a cycle where discomfort disrupts sleep and sleep deprivation worsens ocular inflammation.^22-24 Addressing sleep hygiene, limiting late-night screen exposure, and supporting workplace wellness initiatives reinforces a holistic approach to dry eye management.

Dry eye reflects the interaction between visual demands, workplace environment, and overall health. By addressing lighting, humidity, air quality, ergonomics, vision correction, contact lens use, nutrition, sleep, and mental well-being, Workplace Eye Awareness Month offers a meaningful opportunity to support employee comfort, productivity, and long-term eye health.
