The DuraSoft 3 Colors cosmetic contact lens is manufactured with a pattern of opaque dots applied to its front surface in order to produce a change in apparent iris color. We fit ten subjects with the DuraSoft 3 Colors contact lens, and all were found to have pseudoexotropia. The deviation ranged from 10 to 22 delta (prism diopters) (average: 16 delta). The cause of the pseudoexotropia was creation of a pseudopositive angle kappa from lateral displacement of the contact lens. Physicians fitting the DuraSoft 3 Colors contact lens should pay special attention to centration characteristics during the fitting session in order to avoid creation of pseudostrabismus.
DuraSoft 3 Colors彩色隐形眼镜在其前表面制作了不透明点图案，以改变虹膜的表观颜色。我们为10名受试者佩戴了DuraSoft 3 Colors隐形眼镜，发现所有人都有假性外斜视。斜视度范围为10至22棱镜度（平均：16棱镜度）。假性外斜视的原因是隐形眼镜侧向移位导致假性正角kappa的产生。佩戴DuraSoft 3 Colors隐形眼镜的医生在配镜过程中应特别注意镜片的居中特性，以避免产生假性斜视。
