The utility model relates to a contact lens storage box, which comprises a storage box body filled with cleaning liquid, and a hollow pocket for placing contact lenses is arranged in the storage box body. The contact lens storage box disclosed by the utility model is novel in structure, reasonable in design, convenient and practical, and realizes the functions of cleaning, disinfecting and storing contact lenses; the hollow pocket can separate the contact lenses from the storage box body, the contact lenses can be directly taken out from the hollow pocket, fingers do not need to stretch into the cleaning liquid, the contact lenses are more convenient and easier to take, and meanwhile the cleaning liquid is prevented from being polluted.

A contact lens case is provided that includes a main body, at least two caps, and a lighting circuit. The main body defines at least two lens bays on one side of the main body and a compartment on an opposite side of the main body. One of the caps is removably attached to one of the at least two lens bays and another cap is removably attached to another of the at least two lens bays. A lighting circuit is housed in the compartment. The lighting circuit includes a power source, at least one light source, and a control input to control an illumination state of the at least one light source. The contact lens case provides an indication as to when to change one's contact lenses and / or contact lens case. The contact lens case also provides for remote communication with a user device.

This invention discloses an injection molding process for PP contact lens cases, belonging to the technical field of PP case production processes. The process includes: S1, heating the barrel to melt the PP raw material; S2, preheating the mold by blowing heat from the heat exchange chamber onto the mold using a fan; S3, mold closing and injection molding; S4, cooling and shaping; S5, heating the edges of the PP case to slightly soften the area where the PP case blank contacts the ejector pin; and S6, demolding and removing the part. This invention utilizes a heat exchange chamber on the outer tube of the injection molding machine's injection pipe to conduct residual heat generated during the injection process to the mold preheating area, thereby preheating the mold, reducing the temperature difference between the molten PP and the mold cavity, preventing instantaneous condensation of the melt, and reducing defects such as material shortages and incomplete edges.
