Manufacturers of contact lenses and researchers are joining forces to spread the word about the need to reduce the plastics pollution caused by the many millions of contact lenses being flushed down drains and toilets. Bausch & Lomb, one of the largest makers of contact lenses, cites research findings at the ASU Center for Environmental Health Engineering, directed by Fulton Schools Professor Rolf Halden, for evidence of the negative environmental impact of the problem and of positive results that contacts-recycling efforts could produce.
