Abstract
Official abstract text for this publication.
A container for a contact lens, having a micro-textured pattern on an interior surface thereof to prevent adherence of the lens to the container. In-container inspection of the lens within the container does not recognize the micro-textured pattern of the container as a defect on the lens.
First claim
Opening claim text (preview).
What is claimed is: 1. A container for a contact lens, comprising: a cavity for receiving the contact lens, the cavity having an interior surface, wherein the interior surface of the cavity comprises a plurality of zones, each zone having microstructures of different dimensions thereon; wherein the microstructures having a substantially rounded dome-like configuration, wherein the plurality of zones comprise a first elliptical zone and a second elliptical zone, the first and second elliptical zones each defining a generally elliptical outer periphery, major axes of the generally elliptical outer peripheries of the first and second elliptical zones being aligned generally parallel to one another. 2. The container of claim 1 , further comprising a third elliptical zone, the second and third elliptical zones being arranged on opposite sides of and being smaller than the first elliptical zone. 3. The container of claim 1 , wherein the first elliptical zone has an overall root mean square surface roughness of about 1-1.9 μm, and the second elliptical zone has an overall root mean square surface roughness of about 3-11 μm.
