Eccentric instrument, lens manufacturing method and lens

The invention discloses an eccentric instrument, a lens manufacturing method and the lens. The eccentric instrument comprises a transmission device which is provided with an optical module used for detecting the eccentric value of a to-be-detected lens, a control device used for setting a target height, and a driving device used for driving the transmission device to move the optical module to thetarget height. According to the eccentric instrument, the optical module used for detecting the eccentric value of the to-be-detected lens can be moved to the target height, so that an operator doesnot need to manually adjust the relative position between the optical module and the to-be-detected lens, the detection efficiency is improved, and the detection precision is guaranteed. 本发明公开了一种偏心仪、镜片的制造方法及镜片。其中，偏心仪包括：传动装置，设有用于检测待检镜片的偏心值的光学模组；控制装置，用于设置目标高度；驱动装置，用于驱动所述传动装置移动所述光学模组至所述目标高度。本发明的偏心仪能够将用于检测待检镜片偏心值的光学模组移动至目标高度，从而操作人员无需手动调节光学模组和待检镜片之间的相对位置，既提高了检测效率，又保证了检测精度。
