Are commercial eyedrops safe for daily use?
No. Recent peer-reviewed research has identified microplastic contamination in commercial eyedrop products, raising significant concerns about their safety for daily use.
What's actually in it
Commercial eyedrops are not just sterile saline solutions. A 2026 study in Environ Sci Pollut Res Int confirmed the presence of microplastic contamination in these products. These tiny plastic particles are not supposed to be in a product that you put directly into your eyes.
What the research says
The science is clear: we are introducing foreign materials into our bodies through everyday products. A 2026 study in Environ Sci Pollut Res Int specifically detected and characterized these microplastics in commercial eyedrops.
This is concerning because of how these materials interact with human biology. According to a 2026 systematic review in Environ Health, there is growing evidence regarding the health impacts of microplastics and nanoplastics in humans. Furthermore, a 2026 study in Nephrol Dial Transplant highlights the specific risks these particles pose to organs like the kidneys. When you use contaminated products daily, you increase your exposure to these materials.
