It is intended to provide a method of selecting a contact lens suitable for a wearer and/or a care system therefor, by which the occurrence of problems (for example, worsening in the feel during wearing, lowering in the oxygen permeability of the lens, shortening in the lens life, lowering in the visual acuity, corneal injury, etc.) can be minimized to thereby ensure a high safety for the eye, namely, a method which comprises collecting the lacrimal fluid of a wearer, detecting the protein content and/or the lipid content in the lacrimal fluid thus obtained (Step S 5 ), estimating the dirt adhesion characteristics of the wearer to a contact lens based on the protein content and/or lipid content thus detected, and then selecting a contact lens suitable for the wearer and/or a care system therefor from among a plurality of contact lenses and a plurality of care systems (Step S 6 ). |
