さがある。(Prior Art) Contact lenses are made of transparent or nearly transparent materials. For this reason, for example, when a contact lens is put on or taken off the eye in a washroom, the contact lens may be accidentally dropped on the washroom tiles. In this case, since contact lenses are made of the materials mentioned above, it is difficult to tell whether they are water droplets adhering to the tiles or contact lenses, resulting in the inconvenience of having to spend a lot of effort searching for contact lenses. be.

It is characterized in that a temperature-sensitive coating made of cholesteric liquid crystal or smectic liquid crystal is formed on part or the entire surface.
（実施例）

クトレンズを説明するための断面図である。(Example) FIG. 1 and FIG. 2 are cross-sectional views for explaining a contact lens according to an example of the present invention.
第１図に示す実施例の場合、コンタクトレンズ１の周辺
部にのみ環状に感温性被膜２が印刷によって形成されて
いる。In the embodiment shown in FIG. 1, an annular temperature-sensitive coating 2 is formed only on the periphery of the contact lens 1 by printing.
第２図に示す実施例の場合、コンタクトレンズ１の全面
に感温性被膜２が印刷によって形成されている。In the embodiment shown in FIG. 2, a temperature-sensitive coating 2 is formed on the entire surface of the contact lens 1 by printing.
前記感温性被膜２は、例えば液晶物質で構成することが

配列状態が変化する。所謂、液晶の熱光学効果が顕著に
現われるコレステリンク液晶あるいはスメクテインク液
晶が好適である。The temperature-sensitive film 2 can be made of, for example, a liquid crystal material. Even in this liquid crystal, the alignment state of liquid crystal molecules changes when heated or cooled. Cholesterink liquid crystal or smectinek liquid crystal, in which the so-called thermo-optical effect of liquid crystal appears prominently, is preferred.
コレステリンク液晶であるコレステリルリル−トの温度
範囲は２６〜３５°Ｃ、スメクテイツク液晶であるスメ
クテイツクＡ相を有するビフェニル系液晶化合物の温度
範囲は５〜４３°Ｃである。The temperature range of cholesteryl chloride, which is a cholesterlink liquid crystal, is 26 to 35°C, and the temperature range of a biphenyl liquid crystal compound having a smectic A phase, which is a smectic liquid crystal, is 5 to 43°C.

して感温性被膜を形成する方法が好適である。このよう
にすれば、感温性被膜の形成が容易で薄膜が形成される
とともに、液晶の感温特性が長期間維持できる。When using a liquid crystal compound such as the aforementioned cholesteric liquid crystal or smectic liquid crystal, the liquid crystal compound is encapsulated in minute microcapsules and mixed with a binder such as polyvinyl alcohol or polyacrylamide to create a liquid crystal ink. A preferred method is to print ink onto the contact lens to form a temperature-sensitive coating. In this way, the temperature-sensitive film can be easily formed and a thin film can be formed, and the temperature-sensitive characteristics of the liquid crystal can be maintained for a long period of time.
また他の例として感温性被膜を例えばアンモニア錯体な

できる。As another example, the temperature-sensitive coating can be formed by applying or printing a so-called thermocolor made of an ammonia complex or the like on the surface of the contact lens.

ている。(Effects of the Invention) As described above, the present invention provides a contact lens with a temperature-sensitive coating that changes from colorless to colored, or from light colored to brightly colored, as the temperature of the contact lens decreases when it comes into contact with water. The structure is formed on the surface of the lens.

コンタクトレンズの所在が明確になり、捜すのが非常に
容易になるという利点を有している。Therefore, even if a contact lens accidentally falls on the bathroom tile, the temperature-sensitive film changes color by filling the contact lens with water and lowering its temperature, making it easy to locate the contact lens and find it. It has the advantage that it is very easy to
