Disclosed herein are various embodiments relating to a contact lens treatment that provides significantly improved wetting properties of physical surfaces, such as the surfaces of contact lenses, although other surfaces could be treated with the same treatment for similar effects. These embodiments use oppositely charged particles to ensure a high degree of surface wetting.

The present disclosure generally relates to contact lenses for use with eyes experiencing eye-length related disorders, like myopia. This invention relates to contact lens for managing myopia wherein the contact lens comprises of an optical zone about an optical axis and a non-optical peripheral carrier zone about the optical zone; wherein the optical zone is configured with a substantially single vision power profile providing correction for the eye, and a decentred second region configured with an astigmatic, or toric, or asymmetric power distribution, the second region located substantially away from the optical centre and configured to provide at least in part a regional conoid or interval of Sturm producing an optical stop signal for the eye; and wherein the non-optical peripheral carrier zone is configured with a thickness profile that is substantially rotationally symmetric to further provide a temporally and spatially varying stop signals to reduce myopia progression.

A blister pack 2 assembly 1, for use with contact lenses, comprises at least two thermoplastic base members 4 having a contact lens / solution containing cavity 8 and a top planar surface region 6 sur

This application relates to an artificial tear solution and a method for characterizing the protein removal effect of contact lens solution. The artificial tear solution comprises the following components: PBS buffer, lysozyme, sodium hyaluronate, and sodium formate. This invention effectively prevents protein denaturation and improves the stability of the artificial tear solution by adding sodium formate to a conventional artificial tear solution. The addition of sodium hyaluronate makes the protein more difficult to wash off, thereby effectively improving the adhesion of proteins to RGP lenses. Furthermore, the drying process further fixes the protein, thus enabling a more accurate characterization of the protein removal effect of the contact lens solution.

The application provides a contact lens care solution bottle, comprising a bottle body and a bottle cap, the bottle body is provided with a bottle head, the bottle cap is arranged on the bottle head, a fixing ring is arranged on the lower part of the bottle head, the inner bottom of the bottle cap is provided with a thimble, the bottle head is provided with a bottle eye matched with the thimble, and the thimble can be inserted into the bottle eye. The bottle eye, the fixing ring, the bottle cap and the thimble are matched, the bottle eye is closed in the initial state, the thimble can be directly inserted into the bottle eye to open the bottle eye by covering the bottle cap, the thimble and the bottle eye can open the bottle eye and close the bottle eye, and the exposed area is small due to the thimble and the bottle eye, so that the risk of being polluted in the use process is reduced.

The utility model discloses a flip contact lens care solution bottle which comprises a bottle body and a bottle cap, the top of the plane of a bottle cap body is provided with a solution outlet head extending upwards, the top of the solution outlet head is provided with a solution outlet hole, and a cap corresponding to the solution outlet head is provided with a solution outlet head sleeve; a plug is arranged in the center of the bottom of the liquid outlet head sleeve and is used for plugging the liquid outlet hole; a bottom corner is arranged at the joint of the bottom of the liquid outlet head and the top of the bottle cap body, the liquid outlet head sleeve is cylindrical, an elastic outer edge is arranged at the bottom of the liquid outlet head sleeve and used for being in elastic sealing connection with the bottom corner, and the elastic outer edge is made of soft rubber. The supporting ring is located between the external thread and the check ring, a first step is arranged between the supporting ring and the check ring, and a second step is arranged between the limiting ring and a bottle shoulder of the bottle body. And the step I and the step II are respectively used for mechanical arm clamping in a filling process and a sealing process. Double-layer sealing is formed at the position of the liquid outlet hole, air isolation is good, and the possibility of leakage and deterioration caused by the fact that care liquid makes contact with air is eradicated.

This utility model discloses an automatic contact lens solution filling machine, relating to the field of automatic contact lens solution filling technology. Specifically, it is an automatic contact lens solution filling machine comprising a support frame, a rotating shaft rotatably connected to the top of the support frame, a rotating bracket fixedly mounted on the outer side of the rotating shaft, a placement groove on one side of the rotating bracket, and a container placed inside the placement groove. The rotating shaft is rotatably connected to the top of the rotating bracket, a first driven gear is fixedly mounted on the outer side of the rotating shaft, the rotating bracket is fixedly mounted on the bottom of the rotating shaft, and a clamping frame is fixedly mounted on one side of the rotating bracket.

This invention relates to the field of medical solution preparation technology. Addressing the problems of incomplete and slow neutralization processes in traditional hydrogen peroxide contact lens solutions, which lead to eye irritation risks and low care efficacy, this invention specifically discloses a neutralized hydrogen peroxide contact lens solution, its preparation method, and its usage method. The solution comprises: 2.0-4.0% (w / v) hydrogen peroxide, 0.01-0.5% (w / v) poloxamer, 0.01-0.1% (w / v) diethylenetriaminepentamethylphosphonic acid, and 0.001-0.01% (w / v) UCNP@TiO2 nanomaterials, with the remainder being a buffer system, an osmotic pressure regulator, and purified water. The UCNP@TiO2 nanomaterials are a core-shell composite material with a lanthanide-doped upconversion nanomaterial core and a titanium dioxide shell. This invention introduces UCNP@TiO2 nanomaterials into the nursing solution. Under near-infrared light irradiation, this material can instantly generate a significant killing effect on microorganisms and can also rapidly and completely decompose hydrogen peroxide into water and oxygen, achieving a nursing effect of active light-controlled triggering for disinfection and sterilization.
