| 20120037859 | Photochromic Coating Process - The present invention provides a method for manufacturing a photochromic article having a photochromic compound containing layer. The method includes the step of coating a casting face of at least one mould section with a photochromic host layer. The photochromic host layer is treated to minimise damage during subsequent steps, and a mould is then assembled so that it includes the mould section having the photochromic host layer. The mould is then filled with a photochromic article monomer composition and the monomer composition is subsequently cured to form a photochromic article substrate adhered to the photochromic host layer. The photochromic compound is introduced into the photochromic host layer. | 02-16-2012 |
| 20090141236 | Coatings for Ophthalmic Lens Elements - The present disclosure provides a method of forming a removable protective coating on a hydrophobic surface of an ophthalmic lens element. The method includes providing an ophthalmic lens element having a hydrophobic surface. A non-aqueous coating composition is applied so as to coat at least part of the hydrophobic surface. The composition includes a film forming coating polymer and a compatible non-aqueous solvent. A substantial portion of the solvent is removed from the composition to form a removable protective coating on the ophthalmic lens element that adheres to the hydrophobic surface. The disclosure also provides a removable protective coating, and an ophthalmic lens element having the coating. | 06-04-2009 |
