Contact lens cases are often made of recyclable plastic but are typically too small for standard curbside recycling bins. Automated sorting machines often miss these small items, leading them to landfills or waterways.
- Check for a number 5 recycling symbol on the bottom of the case to identify the plastic type.
- Use specialized recycling programs like the Bausch + Lomb ONE by ONE or Biotrue initiatives for all lens case brands.
- Empty the case and ensure it is dry before dropping it off at a participating eye care office or mailing it in.
- Replace your contact lens case every 3 months to prevent the growth of harmful bacteria and biofilm.
- Avoid flushing old contact lenses or cases down the sink as this contributes to microplastic pollution.
Cardboard packaging and large solution bottles can typically go in regular home recycling bins. Small components like caps and cases require dedicated collection points to ensure proper processing.
