Embodiment 1

[0008] A more comfortable contact lens formula, the raw materials in the formula are composed by weight percentage: 18% polyhydroxyethyl methacrylate, 24% ethylene glycol dimethacrylate, 28% silk protein, 20% Methyl methacrylate, hydrogel 55%, this time more comfortable contact lens formulations increased water content, however not significantly.

Embodiment 2

[0010] A more comfortable contact lens formula, the raw materials in the formula are composed by weight percentage: 20% polyhydroxyethyl methacrylate, 26% ethylene glycol dimethacrylate, 34% silk protein, 22% Methyl methacrylate, 65% hydrogel, a more comfortable contact lens formulation with increased water content but less stability.

Embodiment 3

[0012] A more comfortable contact lens formula, the raw materials in the formula are composed by weight percentage: 19% polyhydroxyethyl methacrylate, 25% ethylene glycol dimethacrylate, 31% silk protein, 21% Methyl methacrylate, 60% hydrogel, a more comfortable contact lens formulation with increased water content and greater comfort on the eyes.

Abstract

The invention discloses a formula of higher-comfortableness contact lenses. The formula is prepared from the following raw materials in percentage by weight: 18 to 20 percent of poly hydroxyethyl methacrylate, 24 to 26 percent of ethylene glycol dimethacrylate, 28 to 34 percent of fibroin, 20 to 22 percent of methyl methacrylate and 55 to 65 percent of hydrogel. A product prepared by a method is more comfortable to wear.

Description

technical field [0001] The present invention discloses a more comfortable contact lens formulation. Background technique [0002] With the development of society, more and more people wear glasses. However, in many cases, the frame glasses will bring a lot of inconvenience, and most contact lenses will cause discomfort to the glasses, and it is difficult to coordinate the stability and water content. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a more comfortable contact lens formula, which is more comfortable. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: a more comfortable contact lens formula, the raw materials in the formula are composed respectively by weight percentage: polyhydroxyethyl methacrylate 18-20%, dimethyl Ethylene glycol acrylate 24-26%, silk protein 28-34%, methyl methacrylate 20-22%, hydrogel 55-65%....
