。Currently, contact lenses are stored in separate containers when not being worn. However, if you accidentally put the container in the wrong container, you may not notice even if the left and right sides are reversed. A person's visual acuity and the shape of the cornea are often different between the left and right sides, and the specifications of contact lenses are also different between the left and right sides, so wearing them incorrectly for a long period of time can be dangerous as it may cause damage to the cornea.

It is preferable that the concentration is such that it does not change the color of the iris or the white of the eye, and that it can be easily distinguished. Specifically, lenses that cover only the iris have a transmittance of 30 to 95% at the maximum absorption wavelength in the visible light region of 400 to 800 nm, and lenses that cover part of the white part of the eye have a transmittance of 30 to 95%. is particularly preferably about 80 to 95%.
実施例１
シーアイ・ソルベント・グリーン３０．３ｇをエタノー
ルと水の混合溶液（体積３／７）１００ｍｌに加え７０
℃の湯浴中で撹拌して分散させ、これを染色液とした。Example 1 30.3 g of C.I. Solvent Green was added to 100 ml of a mixed solution of ethanol and water (volume 3/7).
The mixture was stirred and dispersed in a water bath at 0.degree. C., and this was used as a dyeing solution.
あらかじめ、無色透明なソフトコンタクトレンズを１ベ

して充分に膨潤させ、含水率３８％とした。このソフト
コンタクトレンズを上記の染色液に浸漬してレンズに染
料を染着させた。約１分間浸漬した後レンズを取り出し
、大量の水の中へ投入して洗浄し表面に付着している不
要は染色剤を除去した。得られたソフトコンタクトレン
ズは縁に均一に着色されていた。また他方のソフトコン
タクトレンズには染色を施さなかった。Prepare one colorless and transparent soft contact lens in advance, and immerse either the left or right soft contact lens in a mixed solution of ethanol and water (volume ratio 1/9) to sufficiently swell it to a water content of 38%. And so. This soft contact lens was immersed in the above dyeing solution to dye the lens. After soaking for about 1 minute, the lenses were taken out and washed by putting them into a large amount of water to remove any unnecessary staining agent that had adhered to the surface. The resulting soft contact lens had uniformly colored edges. The other soft contact lens was not dyed.

This was used as a contact lens for either the left or the right. In addition, a colorless and transparent hard contact lens was produced in the same manner as above except for the dye. This was used as the other contact lens.
人の視力や角膜の形状は、左右が異なる場合が多く、そ

な危険を防ぐ効果を有する。A person's visual acuity and the shape of the cornea are often different between the left and right sides, and accordingly, the specifications of contact lenses are also different between the left and right sides. However, you may not notice even if the left and right sides are reversed, and if you continue to wear it incorrectly for a long period of time, it may cause damage to your cornea. According to the present invention, by coloring one of the left and right contact lenses, it becomes possible to easily distinguish between the right and left contact lenses, which has the effect of preventing the above-mentioned dangers.
