摘要： A lens for eyeglasses and a molded synthetic resin for light transmitting filters are disclosed, which can reduce the glare of light and can provide a clear color sense, while retaining the lightness in the field of vision. The lens for eyeglasses and the molded synthetic resin for light transmitting filter are made of a synthetic resin base material comprising an organic dye with an absorption maximum in the vicinity of the central wavelength on the standard relative visibility curve, as well as an ultraviolet light absorbing agent and a blue light absorbing agent, the base material having a transmittance minimum in the range of wavelength extending from 550 to 585 nm on the transmittance curve, the transmittance of light at the transmittance minimum being not greater than 25%, the average transmittance of light over the range of wavelength extending from 590 to 660 nm being not less than 15%, and the average transmittance over the range of wavelength extending from 470 to 550 nm being not less than 10%. The above synthetic resin base material in the lens or the molded synthetic resin may further comprise an infrared light absorbing or reflecting agent.
