Don’t flush contact lenses. Recycle them
We’ve become accustomed to recycling cardboard boxes, aluminum soda cans, plastic water bottles, magazines and other items that we once threw in the trash.
You might not, however, have considered recycling your old contact lenses. Yes, contact lenses can be recycled. But disposing of your contacts in an eco-friendly manner isn’t, unfortunately, as simple as tossing them into a recycling bin.
Follow along to learn the eye-opening do’s and don’ts of properly disposing of your used contact lenses:
Don’t put contact lenses down the drain
An estimated 45 million Americans wear contact lenses. Based on one study, millions of those wearers could be clogging our waterways with their used contacts.
In 2018, an Arizona State University study of contact lens wearers found 15-20% of them were flushing their old contacts down the toilet or washing them down the sink's drain.
On a national basis, the researchers reported, that would amount to 1.8 billion to 3.36 billion lenses being flushed every year.
Put another way, that would translate into 20 to 23 metric tons of plastic trash winding up in our wastewater each year.
As noted by wellness website mindbodygreen.com, contact lenses don’t biodegrade easily because they’re medical devices that are designed to withstand punishment.
“Flushing contact lenses is particularly concerning because their size and flexibility allow them to slip through filters meant to keep nonbiological waste out of wastewater treatment plants,” according to mindbodygreen.com.
Don’t mix contact lenses with the rest of your garbage
Old contact lenses don’t belong in the same trash bag as your expired yogurt and other discarded food, grass clippings and other yard waste, worn-out appliances and tired-looking furniture.
Mindbodygreen.com says that while adding contact lenses to your everyday trash means that plastic won’t flow into our water systems, it’s still being dumped at a landfill.
That’s no better than flushing your contact lenses.

Don’t put contact lenses in the recycling bin
Contact lenses themselves shouldn’t join bottles, cans and other recyclables at your house.
“Due to their size and packaging materials, recycling facilities typically cannot handle contact lens processing, so they are diverted to landfills,” mindbodygreen.com says.
There is, though, a way to recycle the plastic blister packs that contain your contacts.
Online magazine Mental Floss recommends putting empty blister packs inside plastic bottles and then dropping them into your recycling bin once you’ve filled up the bottles.
Remember to remove the foil that covers the blister packs before you shove them into those plastic bottles, though.
Contact lens recycling — it’s a thing
We’ve gone through a few don’ts regarding disposal of contacts. Now, we’ve got one great “do” for you.
In 2016, Bausch + Lomb teamed up with TerraCycle, a handler of hard-to-recycle waste, to create the ONE by ONE Recycling Program.
The program is designed to recycle contact lenses, blister packs and blister-pack foil.
As of April 2019, the recycling program had diverted more than 9.2 million used contacts, blister packs and foil from waterways, landfills and traditional recycling facilities.
Altogether, those materials weighed nearly 28 tons (roughly equivalent to four large African elephants).
How does the ONE by ONE program work?
Once you’ve collected your old contacts, blister packs and foil, you can pick one of two recycling paths:
Take the waste to a local eye doctor’s office. Find a vision practice near you participating in the contact lens recycling program. At this time, drop-off locations aren’t available in Alaska and Hawaii.
Ship it to TerraCycle. If you go the shipping route, you’ll place the waste in a sealed cardboard box and then drop off the box at a UPS location or schedule a pickup from your home.
You don’t need to wash the contact-lens waste before you recycle it, but you should be sure the blister packs are free of liquid.
“Once received, the contact lenses and blister packs are separated and cleaned,” Bausch + Lomb says.
“The metal layers of the blister packs are recycled separately, while the contact lenses and plastic blister pack components are melted into plastic that can be remolded to make recycled products.”
Fortunately, the program accepts used contact lenses and other contact-lens recyclables from any manufacturer, not just Bausch + Lomb.
For every qualifying shipment weighing at least 2 pounds, Bausch + Lomb will donate $1 per pound to Optometry Giving Sight, a global fundraising initiative that seeks to prevent blindness and impaired vision.
Think of recycling your contact lenses as a “win-win” with little effort on your part. Your contact lenses and their packaging are recycled, and you’re helping programs to prevent blindness.

Where does it all go?
Your contacts and packaging are turned into “a variety of post-consumer products, such as recycled picnic tables and garden beds,” Amy Butler, vice president of global environment, health, safety and sustainability at Bausch Health, said in 2018.
That could make it a “win-win-win,” for just a little bit of extra work on your part.
