More Information
Summary: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 monomer are capable of co-reacting to form an abrasion resistant coating on the optical element. The invention also provides a method of forming an abrasion resistant coating on an optical element, such as an ophthalmic lens. The method includes the steps of coating the optical element with a relatively rigid multifunctional monomer and a relatively flexible difunctional monomer, and polymerising the coating to form an abrasion resistant coating on the optical element.
