| 摘要 |
The invention relates to a contact lens having at least two focal lengths, a single lower supporting element (1) enabling the lens to be moved in translation in relation to the eye and a region (9) in the lower part of the lens, which region (9) has an outer face connected to the rest of the outer face (E) of the lens by means of a recess and an inner face merging with the rest of the inner face (i) of the lens, said recess defining the lower supporting element (1). The lens is characterised in that the aforementioned region (9) is thin, having an average thickness (e4) of the same order of magnitude as the thickness (e1) of the upper edge (3) of the lens. |
