The contact lens (1) for observation and treatment by a coherent radiation beam of a working point T of the eye comprises, for example, an entry lens (4) coupled to a contact lens (5) designed to be applied to the cornea of the eye, the optic axes (6) of said lenses being merged. The entry surface of the lens is spherical and is associated with Weierstrass points A and A' and the image of point A' by the rest of the contact lens is merged with said working point T.
