Embodiment Construction

[0018] Wherein, referring to steps and / or features in any one or more figures in the drawings, which have the same reference numerals, those steps and / or features have the same function or operation for description purposes, unless the contrary appears intention.

[0019] Figure 1A to 1C show prior art devices for actively drying eyeglass cases.

[0020] Figure 1A A contact lens storage case 104 and associated lid 101 are depicted. When the lenses are to be stored, contact lenses (not shown) may be placed into the well (also referred to as the cavity) 113 of the case 104 . The lid 101 has threads 102 which engage with threads 103 on the box 104 to close the box 104 when the lid 101 is attached to the box 104 .

[0021] FIG. 1B depicts device 110 having cavity 108 whose surface conforms to the exterior surface of case 104 . Thus, when the heating element 109 is activated by the power supply / control system 111 in the apparatus 110, after the cassette 104 has been inserted i...

Abstract

A method (300) of disinfecting a contact lens storage case (104) having a lid (101). The method comprises the steps of occluding (313) the cavity (113) of the case with the lid; and actively drying (315) the case by heating the case for about three hours at about 60 degrees Celsius.

Description

technical field [0001] The present invention relates generally to contact lenses, their associated storage cases and manner of sanitizing, and in particular, to a method for lowering the contact lens storage case (hereinafter referred to as a contact lens storage case, storage case or case). Methods of microbial growth. Background technique [0002] Contact lenses (hereinafter simply referred to as glasses) are becoming more and more common. This is accompanied by a corresponding increase in the incidence of bacterial keratitis and other eye infections. [0003] Improper box hygiene has been identified as a factor associated with a significantly increased risk of developing eye infections, and several methods are currently used to improve box hygiene. [0004] One such approach is the use of antiseptic solutions to reduce the level of microbes and other foreign particles adhering to contact lenses. In another approach, contact lenses are soaked with silver ions to reduce ...
