The invention relates to a method for detecting a focal point of a contact lens. First, a trial contact lens having a plurality of detection base points can be worn on the surface of the cornea of the eye, and a camera device is used to photograph the invisible contact lens. The eye of the glasses to obtain the shooting picture, and then the electronic device is used to calculate the distance between the complex detection base point and the corner of the eye's sclera from the shooting picture, so as to obtain the position of the focus point of the eye on the contact lens for trying on. The contact lens can be made according to the position of the focus point on the try-on contact lens, so that the optical center of the surface of the contact lens conforms to the center of the visual axis of the eye, thereby making the produced contact lens conform to the correct focus position of the eye, and the eye During the detection process, there will be no objects to cover up and affect the sight, thereby achieving the purpose of improving the accuracy of the detection focus point.本發明為有關一種隱形眼鏡之聚焦點檢測方法，係可先將具複數檢測基點之試戴用隱形眼鏡配戴於眼睛之眼角膜表面上，並利用攝像裝置來拍攝配戴有試戴用隱形眼鏡之眼睛，以取得拍攝畫面，再藉由電子裝置來從拍攝畫面中計算複數檢測基點與眼睛之角鞏膜緣間的距離，以得到該眼睛於試戴用隱形眼鏡上的聚焦點位置，便可再依據試戴用隱形眼鏡上的聚焦點位置來製作隱形眼鏡，以使隱形眼鏡表面之光心符合眼睛的視軸中心，藉此使製作出的隱形眼鏡可符合眼睛正確聚焦位置，且眼睛於檢測過程中，不會有任何的物體來遮蔽、影響視線，進而達到提升檢測聚焦點準確性之目的。
