Contacts tossed in the toilet or sink are clogging up waterways

News

MINNEAPOLIS (KARE) — Contact lenses are vital to the vision of around 45-million Americans, but recently they’ve been in the headlines because of all the waste they are contributing to our waterways.

So why have these tiny lenses become such a huge problem? It has to do with improper disposal of the product.

The fastest-growing part of the contact lens market is daily disposable lenses, which create a lot more waste. Researchers at Arizona State University found up to 20 percent of wearers toss the lenses into sinks and toilets instead of the garbage.

Because disposable lenses are made of durable plastic, they don’t fully break down. To make things worse, after going through a sewage treatment plant the lenses break down into even smaller pieces, which can find their way into fish, birds or other animals.
