ClearImpact of Microplastics on the Ocular Surface
This review examines emerging evidence on how microplastics may affect the surface of the human eye. Researchers found that microplastics can potentially trigger inflammatory responses, microbial imbalance, and oxidative stress in ocular tissues, though research is still limited. The study highlights the need for more investigation into this overlooked exposure route, as the eyes are constantly exposed to airborne particles including microplastics.
Plastic Waste and COVID-19 Incidence Among Hospital Staff After Deescalation in PPE Use
This quality improvement study at a hospital found that scaling back the use of personal protective equipment following national guidelines significantly reduced plastic waste, costs, and carbon footprint without compromising staff safety. The reduction in protective gown use alone led to measurable decreases in plastic waste generation. The findings suggest that PPE protocols can be optimized to reduce environmental impact while maintaining healthcare worker protection.
Microplastics Identified in Commercial Over-the-counter Lubricant Eyedrops
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.
Microplastics identified in commercial over-the-counter lubricant eyedrops
Researchers conducted extensive quantification of microplastic contamination in commercial over-the-counter lubricant eyedrops, finding MPs in multiple product brands at concentrations suggesting direct ocular exposure with each application. The study identified a previously unrecognized route of microplastic exposure with potential implications for eye health.
