Flush­ing con­tact lenses down the toi­let could be con­tribut­ing to the grow­ing prob­lem of mi­croplas­tic pol­lu­tion in the world’s oceans, say researchers at Ari­zona State Univer­sity. They es­ti­mate that up to 10 tonnes of plas­tic lenses make it into waste­water an­nu­ally in the US alone. Once in the wa­ter, the lenses break down to form mi­croplas­tics that can end up be­ing con­sumed by marine an­i­mals.
