The present invention relates to a lens cleaning solution and a method of manufacturing the same, and more particularly, to a lens cleaning solution that can be used for preservation and cleaning of contact lenses and a method of manufacturing the same.

In general, contact lenses are worn directly on the eyeball to compensate for vision, and are widely used as a substitute for eyeglasses for the purpose of vision correction.

People belonging to certain occupational groups where it is difficult to wear glasses, such as athletes, use contact lenses as a means of correcting vision instead of glasses, and contact lenses are also used for the convenience of living without glasses or for beauty purposes. It is used a lot.

In particular, in recent years, a contact lens having a cosmetic function by coating various pigments on the surface of the lens has been provided, so that the purpose of using the contact lens is diversified, and the use layer is widening.

However, if contact lenses are worn for a long time, fats or various foreign substances may adhere to the surface, and these contaminants can cause various eye diseases including eye inflammation, so the surface of the contact lenses is cleaned with a cleaning solution or chemicals. Therefore, it must be kept clean at all times.

For this reason, users who wear contact lenses frequently wash contact lenses by providing a cleaning solution for cleaning the lenses at home or at work. In addition, recently, a solution for moisturizing, washing, rinsing, and removing protein from contact lenses (commonly referred to as preservatives) has been widely used.

However, the conventional lens cleaning solution or lens preservative solution is formed by simply mixing sodium chloride and other additives in purified water, and it has been difficult to achieve improved effects such as strong sterilization effect for impurities or harmlessness to the human body.

In addition, the purified water is preferably formed so that the molecular structure is a hexagonal copper structure.

It is preferable that the purified water is magnetized by the magnetic field of the magnet while passing between the two magnets so that the molecular structure is formed to have a hexagonal ring structure.

A process for converting purified water into hexagonal water and adding and mixing additives to prepare the lens cleaning solution, and a manufacturing apparatus 10 used therefor will be described as follows.

First, as shown in Fig. 1, the step of preparing purified water to form purified water to be water molecules having a hexagonal ring structure, adding an additive including sodium chloride, sorbic acid, and sodium hyaluronate to the purified water, and mixing the purified water and the additive. Through the step of preparing a lens cleaning solution.

Purified water undergoes a process of freezing the purified water, defrosting it again, and magnetizing the purified water as shown in FIG. 2 in order to make the water molecules have a hexagonal ring structure.

One of the conditions in which it is easy to generate hexagonal water is low temperature, and since water molecules are converted into hexagonal rings when water becomes ice, purified water is first frozen and then defrosted to prevent water molecules contained in purified water. Induce it to become a hexagonal ring structure.

Then, the thawed water is magnetized to induce the remaining water molecules that have not been converted into a hexagonal ring structure to become a hexagonal ring structure as much as possible.

An embodiment of a manufacturing apparatus 10 for manufacturing a lens cleaning solution through these steps is shown in FIGS. 3 to 5.

Referring to the drawings, the manufacturing apparatus 10 includes a defroster 100, a discharge passage 200 connected to the defroster 100, a magnetized passage 300 connected to the discharge passage 200, and a magnetized passage ( A plurality of magnets and supply nozzles 400 installed in 300, a cooling unit for keeping the temperature of the discharge passage 200 and the magnetization passage 300 low, and a storage unit 500 for storing purified water and additives, It is installed in the storage unit 500 and includes a stirring unit 600 for stirring so that purified water and additives are mixed.

The defroster 100 is a space for defrosting purified water in ice state, and ice grains of purified water having a predetermined size are put in the defroster 100 and then melted through natural thawing. When the purified water melts, the purified water is discharged from the defroster 100 through the discharge passage 200, and the purified water flow sensor for measuring the discharge amount of the purified water discharged on the discharge port or the discharge passage 200 of the defroster 100 ( 210) is provided.

As described above, as the temperature of water decreases, the molecular structure is more easily maintained in a hexagonal ring shape. Water whose molecular structure has changed once the molecular structure does not change easily even if the conditions change, but the molecular structure of a hexagonal ring can be broken as the structure of some water molecules is transformed into a molecular structure of another shape such as a pentagonal ring due to temperature rise. . Therefore, it is preferable to maintain the temperature of the purified water passing through the discharge passage 200 and the magnetization passage 300 between 2° C. and 6° C. so that the molecular structure can be easily maintained. To this end, temperature sensors 350 are provided for each section on the discharge passage 200 and the magnetization passage 300, and temperature information of the temperature sensors 350 is transmitted to the controller 700 so that the controller 700 Controls the driving of the first cooling unit 340.
