Patent number: 5975695Abstract: An optical element is disclosed comprising an upper portion (9) and a lower portion (8) defined in opposite parts with respect to a median line (x--x) passing through the geometric center (C.sub.1, C.sub.2) of the optical element, wherein the factor of luminous transmittance is between 30% and 80% in the lower portion (8) and between 3% and 40% in the upper portion (9). Advantageously, furthermore, the curve of spectral transmittance as a function of the wavelength in the lower portion (8) and at a distance of at least 10 mm from the median line (x--x) is such as to show: a minimum in a wavelength range of from 495 to 510 nm, ii) an increase in spectral transmittance at wavelengths lower than 495 nm and higher than 510 nm, iii) a maximum at a wavelength lower than 440 nm, iv) a reduction in the spectral transmittance as the wavelength decreases starting from said maximum.Type: GrantFiled: September 10, 1997Date of Patent: November 2, 1999Assignee: Intercast Europe S.P.A.Inventors: Paolo Baiocchi, Giuseppe Iori, Graziano Marusi

Patent number: 4260564Abstract: An improved method for manufacturing spectacle lenses and the like from diglycol allyl carbonate or equivalent plastic by first heating the plastic monomer in the liquid state and containing a polymerization initiator therefor in a planar mold until a degree of polymerization in the range of about 65-85% of completion has been achieved, then removing the partially polymerized material from the mold, subjecting the same to deflection to a curvature corresponding to the desired lens and heating the thus-deflected material until polymerization is complete. Preferably, the initial planar molding step is carried out with a layer or sheet of the material of sufficient size as to contain a plurality of individual lens elements, and after removal thereof from the mold, a plurality of individual lens elements is derived therefrom and such elements are separately subjected to deflection and further polymerization. Preferably, the amount of polymerization initiator exceeds the normally used amount.Type: GrantFiled: August 15, 1979Date of Patent: April 7, 1981Assignee: Intercast Europe S.p.A.Inventors: Paolo Baiocchi, Gian G.
