Patent Number Title Of Patent Date Issued
8128990 Abrasion resistant coating composition March 6, 2012
The invention provides a coating composition for an optical element, such as an ophthalmic lens. The coating composition includes a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer. The rigid multifunctional monomer and the flexible difunctional
8044141 Tinting optical substrates October 25, 2011
The present invention provides a method for tinting an optical substrate. The method includes the steps of applying a coating composition containing: a polymerisable monomer having a polyoxyalkylene backbone containing at least four contiguous oxyalkylene units, and an abrasion res
8003022 Method of forming a coated optical element August 23, 2011
A method of forming a coated optical element is disclosed herein. The method uses a mold having first and second mold sections that will form front and back surfaces of the optical element, one of the mold sections having a casting face. The method includes the steps of: applying an
