摘要： A translucent synthetic material article such as an ophthalmic lens comprises a plurality of well-shaped cells, some of which have at least one upstanding projection on their bottom walls. The projection have a height between 1/5 and 1/1 the cell depth and are upwardly tapering and wedge-shaped. The plurality of cells are arranged in rows and columns to define a matrix. When the translucent article is illuminated, the well-shaped cells with upstanding projections display enhanced contrast compared with such cells without upstanding projections, thereby producing an identification marking or the like.
