CL/V-19064/A/CVE 33 A soft toric contact lens The soft toric contact lens has a substantially rotationally symmetrical front face (1,2) optionally having a rotationally symmetrical lenticular construction (2), and a substantially aspherical, especially ellipsoidal, rear face (7,8). The optically active central region (7) of the rear face (7,8) is torus Shifting the torus to the central region of the lens rear face results in lenses that are economic to produce, are of wearable thickness and are straightforward to fit. (Fig. 1)
