Te Connection Between Improper Contact Lens Disposal and Bakterial Spread

How Improper Contact Lens Disposal Fuels Bakterial Spread

Contact lenses offer a reliable vision accortion option for millions of peolle worldwide. However, a hidden public health has emerged from thee way these lenses are discarded. When used lenses are flushed down toweets, washed down sinks, or tossed into unsanitary trash bins, they carry pathogenic bacteria into water systems and waste fastee fatis.
