[Problems] The invention provides a plastic lens for eyeglasses by using diethylene glycol bisallyl carbonate as a lens material and which is made to have a main absorption peak in a wavelength range of 565 nm to 605 nm by mixing a coloring agent in which a visible light-absorption spectroscopic spectrum contains an azaporphyrin compound and to be durable for use as eyeglasses and polarized eyeglasses owing to the good antiglare and visibility properties of the coloring agent. [Solving means] The eyeglass lens made of an allyl diglycol carbonate resin which has a main absorption peak of visible light spectroscopic transmittance in a wavelength range of 565 nm to 605 nm as shown in FIG. 1 is obtained by using diethylene glycol bisallyl carbonate as a lens material, mixing an organic coloring agent containing a tetraazaporphyrin compound, mixing a peroxyester type peroxide or a peroxyketal type peroxide with a 10 hour-half life temperature of 90 to 110° C. as a polymerization initiator, and polymerizing, defoaming, and curing the lens material. |
