LAMINATED GLASS LENS FOR GLASSES

WIPO Patent Application WO/2011/105211

A1

In order for the disclosed laminated glass lens for glasses to have excellent glare-prevention characteristics, a tetraazaporphyrin compound is combined at a required concentration with an extremely thin adhesive agent layer and is moreover combined in a manner so that unevenness of color does not arise, and of the light-absorbing ability expected of a laminated lens for glasses, there is sufficient shielding of light in the vicinity of the 585 nm wavelength. In the laminated glass lens for glasses, two glass lens substrates (2, 3) (thicknesses of approximately 1 mm) are pasted together with the adhesive agent layer (1) therebetween, and the laminated glass lens for glasses has a main absorption peak of the spectral transmittance factor for visible light at the wavelengths of 565 to 605 nm. A liquid, which is a combination in a predetermined solventless adhesive of a pigment—containing the tetraazaporphyrin compound—along with an organic solvent, is dripped down onto one of the glass lens substrates (2) (in the figure, the liquid drops (1a) are indicated by a dot and dash line) and spread into a layer by a separate glass lens substrate (3) being mounted from above and pressed together with a relatively light load, and the adhesive agent layer (1) is cured at a thickness of 5-150 μm.
