Humidity.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1 , in the first embodiment of the contact lens moisturizing device 100 of the present invention, the contact lens moisturizing device 100 can increase the moisturizing effect of the contact lens while the contact lens is being washed. In the present embodiment, the contact lens moisturizing device 100 includes a housing unit 10 and a control unit 20.

The accommodating area 12 is for accommodating the contact lens and the maintenance liquid. The 12 series are lens grooves, and the number is two, which are not connected to each other and are respectively placed for the left and right eye contact lenses. Of course, the shape of the housing 11 and the accommodating area 12 and the number of the accommodating areas 12 can be adjusted according to different usage requirements, and are not limited to the embodiment.

The control unit 20 is disposed on the housing 11 and includes a control module 21 and at least two electrodes 22 electrically connected to the control module 21 . The control module 21 is a controller that can supply current or an electronic circuit that can generate current or voltage after being powered. In the present embodiment, the number of the electrodes 22 is four. Each of the two electrodes 22 is disposed in a corresponding one of the lens slots (the accommodating region 12), but is not limited thereto, and the electrodes 22 are made of an electrically conductive material, such as a metal. After the two contact lenses are respectively immersed in the accommodating areas 12 in which the maintenance liquid is placed, the control module 21 can apply a current to the maintenance liquid via the electrodes 22, so that the maintenance liquid and the contact lens An inter-molecular interaction occurs, such as electrostatic adsorption. Therefore, the degree of moisturization of the contact lens can be improved, thereby improving the comfort of the user wearing the contact lens.

The combination.

More specifically, when the maintenance fluid is applied with current, the humectant attached to the contact lens can be increased by the intermolecular interaction between the maintenance fluid and the contact lens. For example, when an electrostatically charged object is placed close to another non-static object, the electrostatic induction causes the interior of the non-static object to accumulate charges of opposite polarity to those carried by the electrostatically charged object on the side close to the electrostatically charged object, and The inside of an object with static electricity generates charges of the same polarity as the electrostatically charged object on the other side away from the electrostatically charged object. When the opposite charges are attracted to each other, the phenomenon of "electrostatic adsorption" is exhibited. In this embodiment, the contact lens is non-conductive and does not have static electricity. When the control module 21 is activated and current is supplied through the electrode 22 to pass the maintenance liquid, the humectant of the maintenance liquid can be electrostatically charged. A static humectant can be adsorbed on the surface of a contact lens without static electricity by electrostatic adsorption. Therefore, the humectant can be adsorbed on the contact lens in a large amount to enhance the moisturizing effect of the contact lens.
