The invention relates to glasses. A method of manufacturing a lens element. The lens element is used for an adjustable refractive power lens. The adjustable refractive power lens comprises two lens elements; two lens elements slidable relative to each other in a direction intersecting an optical axis of the lens and having respective lens surfaces shaped together to form a corrective lens; the refractive power of the adjustable power lens varies according to the relative arrangement of the two lens elements. The method includes the steps of forming a lens disk having two opposing faces, where the two opposing faces are shaped to form opposing lens surfaces of one of the lens elements of the adjustable power lens, the disk having at least one alignment feature; thereafter, trimming the disk to a desired eye shape with reference to the alignment feature. 本发明涉及眼镜。一种制造透镜元件的方法，所述透镜元件用于一种可调屈光力透镜，所述可调屈光力透镜包括两个透镜元件，所述两个透镜元件可在与所述透镜的光轴相交的方向上彼此相对滑动，并且具有整形为一起形成矫正透镜的相应透镜表面，所述可调屈光力透镜的屈光力根据所述两个透镜元件的相对布置而变化，所述方法包括以下步骤：形成具有两个
