Problems solved by technology

In addition, non-ionic surfactants including Polyflor Vision and Polyflor Vision have also been used by Bausch & Lomb in contact lens packaging solutions, but the wetting effect is not good. This is most likely because it is generally believed that human tears can provide Proper wetting of new or unused contact lenses and any surfactant on the lens will be quickly removed by tears

Embodiment Construction

[0014] At present, many people use contact lenses to make up for their lack of vision, and some people use contact lenses to decorate their eyes. In general, among contact lenses, there are hard contact lenses mainly composed of methyl methacrylate, soft contact lenses containing 2-hydroxymethacrylate, and N-vinylpyrrolidone or silicone contact lenses. Glasses. Because soft contact lenses and silicone contact lenses have the advantages of short adaptation period, good oxygen permeability and comfortable wearing, they have become the mainstream of contact lenses.

[0015] The contact lens packaging solution of the present invention is basically applicable to any type of contact lens, as long as it does not cause substantial adverse effects on the lens. The contact lens packaging solution of the present invention comprises: a moisturizing ingredient containing sodium hyaluronate, the moisturizing ingredient is present in the packaging solution in an amount of 0.1 to 0.3% by wei...

Abstract

The invention relates to a packaging solution of contact lens including sodium hyaluronate as the moisturizing ingredient which exists in the packaging solution with the amount of 0.1 to 0.3 weight percentage per liter of solution. The comfort of the contact lens which are stored in the packaging solution when being placed in the eye of the wearer is enhanced, the problem that the eyes are dry and uncomfortable when the user wears the lens for the first time is relieved; the packaging solution has the osmotic pressure range of 280 to 320 Osmol / kg, and the pH range of 7.1 to 7.5.

Description

technical field [0001] The invention relates to a contact lens packaging solution, in particular to a contact lens packaging solution containing moisturizing ingredients. Background technique [0002] Contact lens manufacturers typically sell contact lenses to consumers packaged in veneers or vials in which saline or deionized water is used to preserve the lenses, since the lens materials may The problem of self-sticking or sticking to the packaging material occurs, so manufacturers add surfactants, such as polyvinyl alcohol, to the packaging liquid to reduce or eliminate the phenomenon of lens folding self-sticking or sticking to the packaging material. [0003] However, the current packaging procedure of contact lenses requires heat disinfection, because polyvinyl alcohol loses hydration molecules when heated, and loses lubricity on the lens surface. [0004] Also known as wetting agents and lubricants for contact lenses are poloxamine or poloxmer, which are nonionic poly...
