    摘要： The present invention relates to an optical lens for correcting astigmatism. It includes diffractive components whose outlines are delimited by conic section curves having non-degenerate centers. More precisely, in accordance with the invention, the lens includes adjacent diffractive components having hyperbolic or elliptical outlines with a periodicity in r.sup.2 in two mutually orthogonal directions x and y intersecting on the axis of the lens and coinciding with the main axes of the hyperbolas or of the ellipses, which are determined respectively by the equations: .DELTA.r.sub.x.sup.2 =2.lambda..vertline.f.sub.x .vertline.; and .DELTA.r.sub.y.sup.2 =2.lambda..vertline.f.sub.y .vertline.; in which: .DELTA.r.sub.x.sup.2 represents the periodicity in r.sup.2 along the x direction; .DELTA.r.sub.y.sup.2 represents the periodicity in r.sup.2 along the y direction; .lambda. represents the mean utilization wavelength; f.sub.x represents the desired focal length in the X direction; and f.sub.y represents the desired focal length in the Y direction.

    摘要： A multifocal artificial ocular lens has at least two corrective areas, namely a near vision area to correct near vision and a distance vision area to correct distance vision. The transparency of the lens varies in inverse proportion to its illumination. A photochromic substance is incorporated into the material of the lens, which improves optical performance. Applications include central near vision contact lenses.

    摘要： A multifocal ophthalmic lens is disclosed. The power profile (P) of the lens as a function of the height (h) above the axis (A) of the lens and the addition (Add) corresponding to the degree of presbyopia of the wearer is defined by an equation of the form:P(h)=f(P.sub.VL, Add, h)+C(Add, P.sub.VL)h.sup.2 +B(Add, P.sub.VL)in which P.sub.VL is the power required for far vision, f is a function of evolution between the near vision and far vision powers, C(Add, P.sub.VL) is a spherical aberration correction coefficient depending on the addition and on the far vision power and B(Add, P.sub.VL) is a power correction coefficient depending on the spherical aberration coefficient.

    摘要： A contact lens has at least one palpebral boss projecting locally from its external surface in its peripheral area. The palpebral boss is globally elongate in a circumferential direction and the slope P of its crest line at both circumferential ends is in the range 0.020 to 0.140 and preferably in the range 0.040 to 0.080. Applications include contact lenses for centered optical correction and contact lenses for presbyopia.
