A government organization is trying to make youngsters aware of the risks of frivolous use of colored contact lenses, warning that bad hygiene practices could lead to eye infections and severe diseases.

The campaign was launched Monday by the Tokyo-based, government-run Pharmaceuticals and Medical Devices Agency (PMDA), which supervises production and post-market safety of drugs and medical devices.

The agency's website (www.pmda.go.jp/eyecare) carries hygiene tutorials for contact lens users and those considering purchasing them. It stresses the importance of regular checkups and proper care.
