Stop and read this before you wash your contact lenses down the drain

Science Alert: A new report reveals that a shocking amount of contact lens users – nearly 20 percent – dispose of those little plastic circles in a terribly irresponsible way, by flushing them down the toilet or the drain of the sink.
Of an estimated 45 million US contact lens wearers, that’s around 9 million right there. Without realising, they could be contributing to a serious environmental problem.According to new research, an estimated up to 3.36 billion disposable plastic lenses per year end up joining US wastewater systems.
