Facts/Notes:
45 million people in the U.S. alone wear contact lenses. What happens to these lenses when they're swept down the drain is they end up in wastewater treatment plants. The wastewater passes through filters meant to keep out larger bits of waste, but because contact lenses are made from flexible material, they can fold up and get through the filters and end up in aquatic ecosystems. Aquatic animals can mistake fragments of microplastic for food - and the plastics can even wind up back in the human food supply, along with any of the contaminants that tend to stick to plastic.
