    摘要： A progressive simultaneous vision optical lens for correcting presbyopia corresponding to a low addition is of the kind in which the curve representing the proximity (or power) P lies in an area between a lower envelope curve P.sub.inf and an upper envelope curve P.sub.sup having the following polynomial equations: ##EQU1## where h is the height relative to the axis of the optical lens, i.e. the radial distance from the latter. By appropriate choice of the coefficients A'.sub.i and A".sub.i, the near vision area is made relatively large. Applications include contact lenses, intraocular implants and intracorneal lenses.

    摘要： To define a far vision area and a near vision area in a simultaneous vision ophthalmic lens for correcting presbyopia, the curve representing the proximity as a function of the distance from the axis lies within an area between a lower envelope curve and an upper envelope curve with associated specific polynomial equations in which the coefficients depend on the proximity addition corresponding to the degree of presbyopia of the wearer. Either the far vision area or the near vision area is strengthened relative to the other, the corresponding surface areas S.sub.VL, S.sub.VP being related as follows:for strengthened near vision:1.8.ltoreq.S.sub.VL /S.sub.VP .ltoreq.3.6and for strengthened far vision:4.75.ltoreq.S.sub.VL /S.sub.VP

    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： An optical article comprising an optically transparent substrate with a main surface and, covering the main surface, an anti-smudge coating itself at least partially covered by a temporary topcoat, the anti-smudge coating being the result of the hardening of a polymerisable composition comprising: 55% to 80% by weight, preferably to by weight, of a first component A selected among fluorinated compounds, of which only one end of the chain comprises at least one silanol group or silanol precursor and their mixtures, and 45% to 20% by weight of a second component B selected among linear fluorinated compounds, preferably perfluorinated compounds, of which both ends of the chain comprise at least one silanol group or silanol precursor and their mixtures, for 100% by weight of the first component A and the second component B. The first component A and the second component B together accounting for at least 50% by weight of the total weight of the coating. Application to ophthalmic lenses.
