Contact lens case

Abstract

Provided is a contact lens case with a novel structure, capable of easily and stably storing and removing a contact lens in a housing recess, and capable of improving hygiene and safety when storing and removing the contact lens. This contact lens case (10) comprises a container main body (14) provided with a housing recess (12) for housing a contact lens (33) and a solution (23), and a lid (16) that is openably and closably connected to said container main body (14) via a hinge (18). The lens holding body (20) is movably housed in the housing recess (12), and by connecting the lid (16) and the lens holding body (20) through a connecting member (36), the lens holding body (20) can be vertically displaced with the lid (16) through the opening and closing action around the hinge (18). Meanwhile, a displacement restricting means (46, 48) is provided which restricts the rising and falling of the lens holding body (20) to the vertical direction, the depth direction of the housing recess (14).

Description

technical field [0001] The invention relates to a contact lens case, which is used for immersing contact lenses, especially hydrogel soft contact lenses of long-term wear type or regular replacement type, in a preservation solution or for sterilizing the lenses with hydrogen peroxide solution. Background technique [0002] As is well known, the hydrogel soft contact lens of the permanent wear type or the periodic replacement type needs to be soaked in a preservation solution such as physiological saline containing bactericidal ingredients and the like from the time it is taken out from the wearer's eye to its next use. Store in a dry state and protect from drying out or contamination. When a more specific bactericidal effect is desired, contact lenses are soaked in a hydrogen peroxide solution for more than several hours to sterilize. [0003] Incidentally, contact lens cases have conventionally been widely used as structures capable of easily containing and storing liquid ...

AI Technical Summary

Problems solved by technology

Therefore, it is inevitable that the liquid agent overflows on the receiving recess where the finger is inserted, thereby causing a problem that the contact lens cannot be put on unless the liquid agent overflows without causing a problem

In addition, when picking up contact lenses from the liquid solution, there may be a risk that the contact lenses may float in the liquid solution and turn upside down, thereby preventing them from being easily picked up from the storage recess
