It is an object to provide a novel system for supporting contact lens users, who has not been provided with an after-selling support sufficiently, which is able to provide an appropriate support to individual contact lens user so that he can use contact lenses with comfortable. In order to attain the object, an image signal of the user's currently used contact lenses () acquired by a user client apparatus () is transmitted via communication network means (), to a server apparatus () of a supporting entity (). The server apparatus () then obtains lens condition evaluation data, which are stored in memory means () and transmitted via the communication network means () to the user client apparatus () so that the user () can be provided with the lens condition evaluation data.

Contact lens user support system and support method

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), 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).

Method of selecting contact lens and/or care system therefor

An ocular lens material comprising a siloxane-containing polymer obtained by polymerizing a monomer mixture containing (A) a siloxane macromonomer having at least two active unsaturated groups and a number average molecular weight of 2,000 to 100,000; and (B) a vinyl ester of lower fatty acid as essential components. An ocular lens material comprising a polymer obtained by saponification of the siloxane-containing polymer. Processes for producing the ocular lens materials. The ocular lens materials are excellent not only in lipid-stain resistance, wettability and oxygen permeability, but also in flexibility, particularly, shape recovery at the same time.

Ocular lens materials and process for producing the same

A liquid for contact lenses, containing at least one of a polymer (A) having a recurring unit (a) represented by the formula (I): ##STR1## wherein n is 0 or 1 and a recurring unit (b) represented by the formula (II): ##STR2## wherein m is 0 or 1, and a salt of the polymer (A). The liquid for contact lenses can extremely decrease variation of base curve of a contact lens during preservation and shipping, and shows excellent antiseptic effect and excellent antibacterial effect.
