 WILMINGTON, Del., June 14 /PRNewswire/ -- Wesley-Jessen Corporation, the vision care subsidiary of Schering-Plough Corporation (NYSE: SGP) of Madison, N.J., has filed suit here in the United States District Court charging Pilkington Visioncare, Inc. of Menlo Park, Calif., and Pilkington Barnes-Hind Ltd. of Southampton, England, with patent infringement stemming from the importation, use and sale in the United States of NATURAL TOUCH and ELEGANCE colored contact lenses. Wesley- Jessen is seeking an injunction to block further infringement of its patent rights in addition to monetary damages and costs.

 The technical advance enabling contact lenses to alter the appearance of even dark eye color while maintaining a natural look was developed by Wesley-Jessen in the 1980s. The company's DURASOFT COLORS and COMPLEMENTS lines of contact lenses have been a major success.
 Operating in the United States and Canada and through distributors in 51 other countries, Wesley-Jessen is a pioneering developer of contact lenses, manufacturing and marketing a full line of contact lenses. Schering-Plough, Wesley-Jessen's parent company, is a research- based company engaged in the discovery, development, manufacturing and marketing of pharmaceuticals and health care products worldwide.
