How Improper Contact Lens Disposal Fuels Bakterial Spread

Contact lenses offer a releable vision recortion option for millions of metro worldwide. However, a hidden public health issue has emerged mrem thee way these lenses are discarded. When used lenses are flushed down toilets, washed down sinks, or tossed into unsanitary trash bins, they carry pathostic bacteria into water systems and waste streastres. These micobas caste for expendependes, forg bio films that resist depistion and propate.
