Control of the movement of a contact lens on the eye is of particular importance in the case of a toric lens fitted on a toroidal cornea. Lens rotation was measured on 13 eyes fitted with each of three types of spherical contact lenses, regular, prism ballasted-truncated, and truncated only. Edge lift was varied in three steps, and lenses fitted flat and steep were tested for the amount of blink-associated rotation. Rotation can be reduced by decreasing the radius of the base curve or providing truncation and/or prism ballast.
对于安装在环形角膜上的复曲面镜片而言，控制隐形眼镜在眼睛上的移动尤为重要。对分别佩戴三种类型球面隐形眼镜（普通型、棱镜压重-截平型和仅截平型）的13只眼睛进行了镜片旋转测量。边缘提升分三步变化，对平置和陡峭佩戴的镜片进行眨眼相关旋转量测试。可通过减小基弧半径或提供截平设计和/或棱镜压重来减少旋转。
