Summary

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.
