Investigating Microplastic Presence in Eye Drops Using Micro-Fourier Transform Infrared Spectroscopy
AI summary Read the abstract
Using micro-FTIR spectroscopy, researchers detected microplastic particles ≥20 μm in commercial eye drops, finding evidence of plastic contamination in ophthalmic products and recommending further investigation into packaging sources.
The study provides evidence for the presence of MPs ≥20 μm in commercial eye drops. Further investigation into eye drop packaging is essential to discern whether detected particles are manufacturing by-products or expected ingredients. Further studies using micro-Raman spectroscopy are recommended for definitive analysis of MP contamination.

Microplastic contamination in commercial ophthalmic solutions: Exposure, polymer types, and analytical detection methods
AI summary Read the abstract
Researchers found tiny plastic particles called microplastics in common eye drop products, meaning these particles could be getting into your eyes every time you use them. While scientists don't yet know exactly what this means for eye health, the discovery adds eye drops to the growing list of everyday products—including water and food—where microplastics are showing up, raising questions about long-term exposure that need more research.
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.
Fluorescence Microscopy and FTIR-Based Analysis of Microplastics in Facial Personal Care Products
AI summary Read the abstract
Researchers analyzed twenty facial care products, including scrubs and face washes, for the presence of microplastics using fluorescence microscopy and FTIR spectroscopy. All samples tested positive for microplastics, with polystyrene and polyurethane identified as the most common polymers in scrubs, and ethylene-propylene copolymer and polystyrene predominant in face washes. The findings highlight the widespread presence of microplastic particles in everyday personal care products and the need for stronger regulatory measures.
Complementary Analysis for Undetectable Microplastics from Contact Lenses to Aquatic Environments via Fourier Transform Infrared Spectroscopy
AI summary Read the abstract
Researchers demonstrated that contact lenses discharged into aquatic environments generate microplastics and nanoplastics, using Fourier Transform Infrared Spectroscopy to detect and quantify these previously undetectable particles from a common consumer product.
Quantification of Microplastics in Treated Drinking Water Using µ-FT-IR Spectroscopy: A Case Study from Northeast Italy
AI summary Read the abstract
Researchers quantified microplastics in treated drinking water from a treatment plant in northeast Italy using micro-Fourier transform infrared spectroscopy. The study found that microplastics persist through the water treatment process and end up in drinking water, though the full health implications of ingesting these particles remain not yet fully understood.
