International Classification:

D06N 704

US Classification:

428143, 428149, 428164, 428172, 428180, 428212, 427198, 427212, 4273978, 427540, 427554, 427569, 264482, 264483

Abstract:

An article is disclosed that has a patterned surface containing alternating hydrophobic and hydrophilic surface regions. The hydrophobic regions may be sufficiently narrow such that under dew conditions moisture accumulated on the hydrophobic region migrates to the hydrophilic region, thus preventing the accumulation of water droplets. In frost conditions, the hydrophobic region remains relatively frost-free, thus maintaining at least partial transparency of the surface. Inorganic oxide particles on the surfaces of the hydrophobic regions may provide abrasion resistance. A method for making the patterned surfaces is disclosed in which a treatment removes organic binder to expose inorganic oxide particles at the surface of the hydrophilic regions.

International Classification:

G02C 702

US Classification:

351159

Abstract:

The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a homopolymer or copolymer of epsiloncaprolactone, have a number average molecular weight between 3,000 and 100,000, and a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.

US Classification:

156245

Abstract:

The present invention provides methods of holding ophthalmic lens blanks using thermoplastic lens blocking compositions. Preferred compositions either comprise a homopolymer or copolymer of epsilon-caprolactone, have a number average molecular weight between 3,000 and 100,000, or have a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one method, the composition is injected into the cavity between a preformed lens block and a lens. In another method, the surface of a lens block comprising the thermoplastic lens blocking composition is heated and formed against the lens blank. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.
