Can we treat dry eyes without destroying our planet? a critical analysis of environmental sustainability in dry eye disease management
AI summary Read the abstract
This review pulls together existing research on how dry eye treatments affect the planet, and finds that single-use eye drop vials create far more plastic waste than multi-dose bottles, plus air pollution itself may worsen dry eye symptoms. Switching to reusable packaging, video checkups, and smarter medication storage could cut waste significantly without sacrificing eye care quality.
PURPOSE: To analyze the environmental impact of dry eye disease management and identify evidence-based strategies for sustainable healthcare delivery in ophthalmology. METHODS: This review synthesizes current literature examining environmental consequences of dry eye disease treatment protocols, waste generation patterns, patient transportation emissions, and emerging sustainable solutions. RESULTS: Single-dose delivery systems generate substantially higher plastic waste compared to multi-dose alternatives, with German data showing treatment waste increased from 7.13 to 20.64 tons between 2016 and 2021. Patients produce median annual plastic waste of 0.64 kg from single-dose dispensers versus 0.13 kg from multi-dose systems, while serum therapies generate up to 3 kg annually per patient. Transportation patterns contribute significantly to carbon emissions, with patients attending median 3 yearly appointments and 62% traveling by automobile. Energy-intensive cold storage requirements for specialized treatments further compound environmental impact. Epidemiological evidence reveals concerning connections between air pollution and dry eye disease occurrence, creating cyclical patterns of environmental damage and increased treatment needs. CONCLUSION: Transitioning to multi-dose preservative-free packaging, biodegradable delivery materials, telemedicine-supported follow-up, optimized cold-chain management for biological therapies, and improved recycling infrastructure can substantially reduce the environmental footprint of dry eye disease care without compromising clinical efficacy. Clinical implementation should be risk-stratified, as remote assessment remains constrained by dry eye disease's reliance on slit-lamp-based clinical signs, and further health economic and life-cycle assessment data are needed to guide policy and practice. Enhanced patient education and regulatory frameworks prioritizing sustainability remain essential for a successful transition toward carbon-neutral dry eye disease care.

Identification of microplastics in human tear fluid and meibum: Implications for dry eye disease pathogenesis
AI summary Read the abstract
For the first time, researchers confirmed the presence of microplastics in human tear fluid and the oily secretions of the eyelid glands (meibum), with polyethylene being the most common type found. Higher polyethylene levels correlated with worse dry eye disease symptoms. In lab and mouse experiments, polyethylene exposure damaged eye surface cells and triggered inflammation, suggesting airborne microplastics may contribute to dry eye disease.
Detection and characterization of microplastics in commercial eye drops: A novel ocular exposure pathway
AI summary Read the abstract
Researchers tested commercial eye drop products for microplastic contamination using multiple analytical methods and found microplastics present in all tested brands. The particles were mostly smaller than 100 micrometers and composed primarily of PVC, polyethylene, and polypropylene, identifying eye drops as a previously unrecognized route of direct ocular microplastic exposure.
Microplastics Identified in Commercial Over-the-counter Lubricant Eyedrops
AI summary Read the abstract
Researchers tested nine commonly used over-the-counter lubricant eyedrops sold in single-use plastic vials and found microplastic particles in all of them. The microplastics came from the vial packaging material itself, with higher concentrations found in preservative-free formulations. The findings raise concerns about a previously unrecognized route of microplastic exposure directly to the eye surface through everyday eye care products.
Exposome for Ocular Diseases: From Exposure Evidence to Causality and Actionable Prevention
AI summary Read the abstract
Your eyes are constantly exposed to environmental stressors, air pollution, harsh weather, heavy metals, and even tiny plastic particles, and this review pulls together existing research showing how these exposures can contribute to eye problems ranging from dry eye to cataracts, glaucoma, and retinal disease. The takeaway: eye health isn't just about genetics or aging, what's in your air, water, and surroundings matters too, and understanding these links can help guide prevention strategies and policies to protect your vision over your lifetime.
