Embodiment 1
[0037] Solutions 1-3 and comparative solutions 1-3 were prepared according to the compositions shown in Table 1 below. And use hydrochloric acid or sodium hydroxide pH adjuster to adjust the pH value of each solution and comparison solution.

[0040] Element
[0041] Using Solution 1, Solution 2 and Comparative Solution 1 shown in Table 1 above, the adsorption amount of polylysine on contact lenses was investigated. In this example, the fourth group lens "Shuabyu-" (manufactured by Johnson End Johnson Corporation) was used. For a single treatment, the lenses were immersed in 4 ml of each solution, and left to stand in Solution 1 and Solution 2 at 25° C. for 24 hours, and in Comparative Solution 1 for 8 hours. The 13 treatments were to immerse the lens in 4ml of each solution, and let it stand for 4 hours at 2...
Embodiment 2
[0047] The effect of ε-polylysine on the human eye when adsorbed on contact lenses was studied. In this example, the fourth lens group "Syuabyu-" and "2ゥイ-クアキビュ-" (manufactured by Johnson End Johnson Corporation) were used. After wearing these lenses for a whole day, the lenses were removed from the eyes, and the lenses were washed with the solutions of solution 1, solution 2, solution 3 and comparative solution 1 shown in Table 1 for more than 5 seconds, and then the lenses of the left and right eyes were washed. Each was immersed in a lens case containing each solution, and left to stand overnight. The contact lenses were removed from the lens case the next morning and worn without washing. The contact lenses were worn repeatedly for 2 weeks and treated with solution 1, solution 2 or solution 3, respectively, every day. For contact lenses treated with comparative solution 1 every day, try to wear them for 2 weeks, and stop wearing them if problems arise in wearing them. T...
Embodiment 3
[0052] According to the Stand alone test specified by ISO, the disinfection effect experiment was carried out using solution 1, solution 2, solution 3, comparison solution 2 and comparison solution 3 shown in Table 1. The results are shown in Table 4.
