Contact lens case

Abstract

A contact lens case includes first and second containers each including a wall having an inner surface defining a interior well for receiving first and second lens of a pair of contact lenses. The exterior of the first container is configured differently from the exterior of the second container to provide for both visual and tactile differentiation between the first and second containers. Each of the containers includes a visual indicator on the inner surface of the wall of the container. The visual indicators of the first and second containers differ from each other to provide for visual differentiation between the interior wells of the first and second containers.

1 . A contact lens case comprising: 
 a first container; and    a second container,    the first and second containers each including a wall having an inner surface defining an interior well, the wells of the first and second containers respectively adapted for receiving a first lens and a second lens of a pair of contact lenses,    the first container and second containers having exteriors, the exterior of the first container configured differently from the exterior of the second container to provide for both visual and tactile differentiation by a user between the first and second containers,    each of the first and second containers including a visual indicator defined on the inner surface of the wall of the container, the visual indicators of the first and second container differing from each other in appearance to provide for visual differentiation between the wells of the first and second containers.    
     
     
         2 . The contact lens case according to  claim 1 , wherein the visual indicator defined on the inner surface of the wall of each container includes either one or both of a pattern or symbol.  
     
     
         3 . The contact lens case according to  claim 2 , wherein the visual indicator defined on the inner surface of the wall of the first container includes the letter L for identifying that the well of the first container is adapted for receiving a left lens of a pair of lenses having left and right lenses.  
     
     
         4 . The contact lens case according to  claim 1 , wherein each of the first and second containers includes a flange on the exterior of the container, the flange of the first container having a periphery that includes a plurality of substantially linear edges and the flange of the second container having a substantially circular periphery for visual and tactile differentiation between the first and second containers.  
     
     
         5 . The lens case according to  claim 4 , wherein the substantially linear edges of periphery of the first container flange define at least a portion of an octagon shape about at least part of the first container.  
     
     
         6 . The lens case according to  claim 4  further comprising at least one web connected to the flanges of each of the first and second container.  
     
     
         7 . The lens case according to  claim 1 , wherein the inner surface of the wall of each container includes a substantially cylindrical portion defining an opening at a top end of the interior well, the wall of the container including a substantially planar and circular portion at a bottom end of the interior well, the wall of the container including an intermediate portion between the substantially cylindrical portion and the substantially planar and circular portion, the intermediate portion of the wall having an inner surface that is concavely curved.  
     
     
         8 . The lens case according to  claim 1 , wherein the visual indicator defined on the inner surface of the wall of the first container includes the letter L on the substantially planar and circular portion of the wall for identifying that the well of the first container is adapted for receiving a left lens of a pair of contact lenses having left and right lenses.  
     
     
         9 . The lens case according to  claim 1 , wherein each of the first and second containers includes a cover removably received by the wall of the container for closing an open end of the container adapted for receipt of the associated lens within the well of the container.  
     
     
         10 . The lens case according to  claim 9 , wherein the wall of each container includes a substantially cylindrical portion defining the open end of the interior well, the wall including external threads defined on an outer surface of the wall adapted for threaded engagement with internal threads defined by the removable cover.  
     
     
         11 . A lens case adapted for storing a pair of contact lenses having left and right lenses, the lens case comprising: 
 a left compartment for the left lens of the pair of contact lenses; and    a right compartment for the right lens of the pair of contact lenses,    the left and right compartments each including a wall having an inner surface defining a well for receiving the associated lens of the pair of contact lenses,    each of the left and right compartments including a removable cover for enclosing the associated lens within the well of the compartment,    the left and right compartments each including a flange located on an outer surface of the wall, the flanges configured differently from each other to provide for visual and tactile differentiation between the left and right compartments,    each of the left and right compartments including a visual indicator defined on the inner surface of the compartment wall, the visual indicators of the left and right compartments differing from each other in appearance to provide for visual differentiation between the wells of the compartments.    
     
     
         12 . The lens case according to  claim 1 , wherein at least one of the visual indicators comprises formations on the inner surface of the associated compartment wall adapted to provide a tactile differentiation between the wells of the left and right compartments is provided.  
     
     
         13 . The lens case according to  claim 12 , wherein the formations include raised ribs on the inner surface of the wall.
