Problems solved by technology

However, a problem has also been exposed during a period of use. After the contact lens is soaked in a nursing solution for disinfection and / or protein removal, and is worn directly, part of the disinfectant and / or protein removal agent can be brought into the eyes. For long-term use, disinfectants and / or protein removers can gradually destroy the self-cleaning system of the eye, which may lead to the loss of the self-cleaning function of the eye, secondary infection, eye discomfort, keratitis and other eye diseases

Embodiment 1

[0024] A contact lens cleaning liquid composition, its prescription is: sodium hyaluronate 0.005 g, benzalkonium bromide 0.005 g, water for injection added to 100 ml. The resulting composition had an osmotic pressure of 5 milliosq / liter and a pH of 6.8. Its usage is: take the contact lens that has been sterilized and / or deproteinized, rinse the front and back of the contact lens several times with a small amount of Example 1, then place the contact lens in Example 1 of the present invention, soak for 2 to 4 minutes, and take out Contact lenses are ready to wear.

Embodiment 2

[0026] A contact lens cleaning liquid composition, its prescription is: 2.5 grams of glycerin, 0.03 grams of methylparaben, 0.01 grams of propylparaben, and water for injection is added to 100 milliliters. The osmotic pressure of the obtained composition was 288 mOsm / L and the pH was 7.1. Its usage is: take the contact lens that has been sterilized and / or deproteinized, rinse the front and back of the contact lens several times with a small amount of Example 2, then place the contact lens in Example 2 of the present invention, soak it for 2 to 5 minutes, and take it out Contact lenses are ready to wear.

Embodiment 3

[0028] A contact lens cleaning solution composition, the prescription of which is 0.005 grams of sodium hyaluronate, 0.5 grams of chondroitin sulfate sodium, 2.2 grams of glycerin, 0.005 grams of benzalkonium chloride, and adding water for injection to 100 milliliters. The resulting composition had an osmotic pressure of 256 mOsm / L and a pH of 6.5. Its usage is: take the contact lens that has been sterilized and / or deproteinized, rinse the front and back of the contact lens several times with a small amount of Example 3, then place the contact lens in Example 3 of the present invention, soak it for 2 to 5 minutes, and take it out Contact lenses are ready to wear.

Abstract

The invention provided a washing liquid compound for the contact lens. The batch formula is: at least one active agent, at least one antiseptic, the water, not or containing nonionic osmotic regulation agent, not or containing the non-ionic surface active agent, not or containing the non-ionic refrigerant. It can slake the disinfectant or the deproteinized agent of the contact lens, so it can avoid the illness of the eyes caused by the disinfectant or the deproteinized agent.

Description

Technical field: [0001] The invention belongs to the field of sanitary products, cosmetics or medical equipment, and provides a contact lens cleaning liquid composition, which basically consists of: at least one active ingredient, at least one antibacterial agent, water, and may or may not contain non-toxic Inorganic ion-type osmotic pressure regulator, with or without non-ionic surfactant, with or without non-ionic cooling agent. Background technique: [0002] At present, the number of people wearing contact lenses is increasing day by day. When wearing contact lenses, the contact lenses must be disinfected to effectively avoid eye infections. Therefore, except that there are various contact lenses on the market, there are also multiple care solutions that have disinfection and / or protein removal and / or protective effects on contact lenses, and these solutions generally contain disinfectants (such as peroxide hydrogen, etc.) and / or deproteinizing agents (such as proteases,...
