Abstract
Official abstract text for this publication.
A contact lens package includes a silicone hydrogel contact lens, a packaging container composed of a polypropylene, and a packaging solution containing a nonionic surfactant, the nonionic surfactant including a linear alkyl moiety having 12 or more carbon atoms and an oxyethylene moiety, the average addition mole number of oxyethylene being 30 or more per mole of the nonionic surfactant.
First claim
Opening claim text (preview).
The invention claimed is: 1. A contact lens package comprising: a silicone hydrogel contact lens having a Young's modulus of 1.2 MPa or less; a packaging container composed of a polypropylene; and a packaging solution containing a nonionic surfactant, the nonionic surfactant comprising a polyoxyethylene hydrogenated castor oil serving as the nonionic surfactant, the polyoxyethylene hydrogenated castor oil including a linear alkyl moiety having 12 or more carbon atoms and an oxyethylene moiety, the polyoxyethylene hydrogenated castor oil having an average addition mole number of oxyethylene of 30 or more per mole of the polyoxyethylene hydrogenated castor oil, and a concentration of the polyoxyethylene hydrogenated castor oil in the packaging solution is 0.001% or more by mass and 0.1% or less by mass. 2. The contact lens package according to claim 1 , wherein a difference in relative density between the packaging solution and the silicone hydrogel contact lens is 0.1 or less. 3. The contact lens package according to claim 1 , wherein the average addition mole number of oxyethylene is 30 or more and 100 or less. 4. The contact lens package according to claim 1 , wherein the average addition mole number of oxyethylene is 40 or more and 100 or less. 5. The contact lens package according to claim 1 , wherein the silicone hydrogel contact lens is made from a urethane bond-containing polydimethylsiloxane macromonomer. 6. The contact lens package according to claim 1 , wherein the silicone hydrogel contact lens has a Young's modulus that is in a range of from 0.4 MPa to 1.2 MPa. 7. The contact lens package according to claim 1 , wherein the concentration of the polyoxyethylene hydrogenated castor oil is 0.001% or more by mass and 0.08% or less by mass. 8. The contact lens package according to claim 1 , wherein the concentration of the polyoxyethylene hydrogenated castor oil is 0.001% or more by mass and 0.02% or less by mass. 9. A method for producing a contact lens package, comprising: sealing a silicone hydrogel contact lens and a packaging solution in a packaging container composed of a polypropylene, wherein the silicone hydrogel contact lens has a Young's modulus of 1.2 MPa or less, the packaging solution contains a nonionic surfactant, the nonionic surfactant comprising a polyoxyethylene hydrogenated castor oil serving as the nonionic surfactant, the polyoxyethylene hydrogenated castor oil including a linear alkyl moiety having 12 or more carbon atoms and an oxyethylene moiety, the polyoxyethylene hydrogenated castor oil having an average addition mole number of oxyethylene of 30 or more per mole of the polyoxyethylene hydrogenated castor oil, and a concentration of the polyoxyethylene hydrogenated castor oil in the packaging solution is 0.001% or more by mass and 0.1% or less by mass.
