Hoya Corporation is a Japanese company manufacturing optical products such as photomasks, photomask blanks and glass magnetic-memory disks, contact lenses and eyeglass lenses using wavefront technology[clarification needed] for the health-care market, medical photonics, lasers, photographic filters, and software. Hoya Corporation is one of the Forbes Global 2000 Leading Companies and Industry Week 1000 Company.

Hoya acquired the camera company Pentax in 2007, for the price of US$1 billion, about 10% more than Pentax was valued at the time. In June 2010 the grandson of the corporation's founder Yutaka Yamanaka  proposed changes to the Board of Directors to prevent what he called such "mistakes" from happening again.

On October 1, 2011, Hoya sold its Pentax camera business to Ricoh.
