摘要:
A shoe includes a protective wrap disposed inside an upper and includes a sole portion disposed removably on a sole unit, and two side portions extending upwardly and respectively from two sides of the sole portion and connected to a fastening unit. When the fastening unit is tightened, the fastening unit pulls the side portions, and the side portions lift the sole portion so that the protective wrap is wrapped tightly around the foot of the wearer.
摘要:
A shoe includes an upper having a heel portion that has a rear wall adapted to extend around the heel of a foot. At least one adjustment pad is attached loosely to the rear wall within the heel portion. The adjustment pad includes an intermediate part, first and second ends on two opposite sides of the intermediate part, a first surface confronting the rear wall, and a second surface opposite to the first surface. A strap passage unit is provided on the rear wall. A strap is attached to the adjustment pad, and passes movably through the strap passage unit. When the strap is pulled to move through the strap passage unit, the strap is tensed, and the adjustment pad is moved inward so as to abut against the foot in the shoe.

摘要:
Silicone hydrogel contact lenses are formed from the reaction product of a polymerizable composition comprising at least one acrylate-containing siloxane monomer, at least one hydrophilic vinyl-containing monomer, and at least one vinyl-containing cross-linking agent. The contact lenses have ophthalmically-acceptable ionoflux values and surface wettability, and can be manufactured without the use of volatile organic solvents.
摘要:
Silicone hydrogel contact lenses are formed from the reaction product of a polymerizable composition comprising at least one acrylate-containing siloxane monomer, at least one hydrophilic vinyl-containing monomer, and at least one vinyl-containing cross-linking agent, wherein the polymerizable composition has a molar ratio of total amount of hydrophilic vinyl-containing monomer to total amount of acrylate-containing siloxane monomer of from 5:1 to 30:1, respectively. The silicone hydrogel contact lenses have good manufacturing processability, can be manufactured without the use of alcohol solvents, and have excellent surface wettability.
摘要:
Silicone hydrogel contact lenses are produced without using volatile organic solvents to extract materials from the polymerized contact lens bodies, and instead are washed with aqueous liquids. The silicone hydrogel contact lenses so produced have ophthalmically wettable lens surfaces. The hydrated silicone hydrogel contact lenses have diameters that are at least 24% larger than the diameters of the silicone hydrogel contact lenses prior to hydration or washing.
摘要:
Silicone hydrogel contact lenses having ophthalmically acceptable levels of energy loss are described. The lenses are derived from a polymerizable composition including a first siloxane monomer represented by formula (1): wherein m of formula (1) represents one integer from 3 to 10, n of formula (1) represents one integer from 1 to 10, R1 of formula (1) is an alkyl group having from 1 to 4 carbon atoms, and each R2 of formula (1) is independently either a hydrogen atom or a methyl group; the lenses also include units derived from a second siloxane monomer which is a dual-end methacrylate end-capped polydimethylsiloxane having a number average molecular weight of at least 7,000 daltons. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
摘要:
A contact lens is provided that has extended and rechargeable wettability. The contact lens includes a lens body that is a reaction product of a polymerizable composition. A first polyhydric alcohol having a 1,2 diol or 1,3 diol moiety is present on a lens surface of the lens body. A contact lens package including the contact lens, and methods of producing and using the contact lens, are also provided.
摘要:
Silicone hydrogel contact lenses having ophthalmically acceptable surface wettabilities are obtained from pre-extracted polymerized silicone hydrogel contact lens products having relatively large amounts of removable or extractable materials. The silicone hydrogel contact lenses can be obtained from non-polar resin based contact lens molds and without surface treatments or an interpenetrating polymeric network of a polymeric wetting agent. Related lens products, polymerizable compositions, and methods are also described.
摘要:
Ophthalmically acceptably wettable silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including a first siloxane monomer. The lenses have ophthalmically acceptably wettable lens surfaces when fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
