Embodiment

[0161] Hereinafter, examples of the present invention will be described. However, the present invention is not limited to the following examples.

[0162] [Reference Example A]

[0163] As Reference Example A, modification treatment using a liquid reaction system (hydrophilization treatment step) was performed.

reference example A1

[0165] As the organic phase, a fluorosolvent (CF 3 (CF 2 ) 4 CF 3 ). On the other hand, sodium chlorite (NaClO), which is the source of the above-mentioned carbon dioxide free radicals, 2 ) and acid ie HCl dissolved in aqueous solvent (H 2 O), prepare the aqueous phase. In the above aqueous phase, the final concentration of sodium chlorite is 500mmol / L, and the final concentration of HCl is 500mmol / L. 2 mL of the above-mentioned aqueous phase and 5 mL of the above-mentioned organic phase were put into the same reaction vessel and brought into contact with each other to prepare a two-phase reaction system. In the above-mentioned two-phase reaction system, the organic phase of the above-mentioned fluorine solvent is the lower layer, and the above-mentioned aqueous phase is the upper layer. In addition, a polypropylene film was put into the above-mentioned reaction container. The above-mentioned film is in a state of sinking into the organic phase of the above-mentioned l...

reference example B1

[0171] Fluorinated solvent (CF 3 (CF 2 ) 4 CF 3 ) 4mL, water (H 2 O) 2mL, sodium chlorite (NaClO 2 ) 90 mg and 20 μL of 35% hydrochloric acid (HCl) were added to the same reaction vessel and stirred for 5 minutes. The above-mentioned reaction vessel was left to stand, and separated into an organic phase, an aqueous phase, and a gas phase of the fluorine solvent from bottom to top. In addition, it was confirmed that the above-mentioned organic phase was yellow, and that white gas was generated in the above-mentioned gas phase. Chlorine dioxide radicals are generated in the above-mentioned aqueous phase and dissolved in the more stable above-mentioned organic phase (fluorinated solvent). That is, the yellow change of the above-mentioned organic phase means the generation of chlorine dioxide radicals, so in this reference example, the generation of chlorine dioxide radicals was confirmed. In addition, if chlorine dioxide radicals are dissolved in the above-mentioned organi...

Abstract

The present invention provides a novel method for easily producing a lens to be fitted to eye at low cost. In order to achieve the above-described purpose, a method for producing a lens to be fitted to eye according to the present invention comprises a hydrophilization step wherein the surface of a polymer lens is reacted with compound radicals so as to be hydrophilized; and the compound radicalscontain a group 17 element and one element that is selected from the group consisting of group 15 elements and group 16 elements.

Description

technical field [0001] The present invention relates to a method for manufacturing an eyewear lens and an eyewear lens. Background technique [0002] In the field of ophthalmology, lenses worn on the eye include, for example, lenses worn on the surface of the eyeball (hereinafter also referred to as ocular surface lenses), lenses worn inside the eye (hereinafter referred to as intraocular lenses), and the like. The ocular surface lens is a detachable contact lens (hereinafter referred to as a detachable contact lens), such as a hard contact lens (HCL), a soft contact lens (SCL), and the like. Among them, in recent years, silicone hydrogels have become mainstream as a raw material for soft contact lenses (Patent Documents 1 and 2, etc.). The intraocular lens is, for example, an intraocular lens lens that removes a crystalline lens whose function has been reduced by cataract or the like and is inserted into the eye instead of the crystalline lens (Patent Document 3, etc.), or...
