Who doesn’t see this happening?

Via Axios:

Billions of contact lenses get flushed down the drain every year in the U.S., and researchers from Arizona State University have discovered it takes more than a week for the lenses to even begin to disintegrate, according to research detailed in Scientific American.

Why it matters: Given that most lenses would not spend much longer than a week in a waste facility, the researchers estimate that as much as 50,000 pounds of lenses end up in sewage and up to about 28,000 pounds of that ends up in the dirt, where it could possibly carry contaminants.

The big picture: Contact lenses are still a relatively small problem, especially when looking at the eight million metric tons of plastic pollution that ends up in the oceans every year, according to SciAm. However, experts are increasingly focused on microplastics as a particularly ubiquitous and harmful part of the global plastics pollution problem.

Be smart: The complicating factor comes with contact lenses’ absorption capabilities.

“I would be concerned that there would be more of an impact with these microplastics than with the other materials,” Sherri Mason, a professor of chemistry at the State University of New York at Fredonia, told SciAm, “because of their ability to absorb various toxins in the environment, like pesticides and herbicides, and really hyper-concentrate these chemicals and move them into the food chain and up the food chain.”
