<p>A wrap-around lens (2) for spectacles (1, 100, 200, 300) is described and is defined by a first surface and a second surface (3a, 3b) which are spaced apart and disposed opposite one another, the first surface (3a) having a continuous geometrical curve (S, S', S'') as its cross-section in a longitudinal plane (X, Y). The continuous geometrical curve (S, S', S'') comprises at least a first part (5) and a second part (6, 7) which are contiguous and each of which includes an arc of a circle, and the tangent to the geometrical curve at the point of connection of the first part to the second part is continuous.</p> |
