description Una lente de gafa (10) para reducir la transmitancia en al menos dos zonas del espectro de luz visible, incluyendo: un primer filtro de bloqueo limitado y controlado (30) que tiene una longitud de onda de bloqueo máximo de entre 430 nm y 480 nm, y una transmitancia mínima en la longitud de onda de bloqueo máximo de entre 55% y 75%; y un segundo filtro de bloqueo limitado y controlado (30) que tiene una longitud de onda de bloqueo máximo de entre 530 nm y 620 nm, y una transmitancia mínima en la longitud de onda de bloqueo máximo de >= 65%, donde una transmitancia luminosa general de la lente de gafa es >= 75%. The present invention is embodied in an eyewear lens with at least two controlled, limited visible light blocking filters that attenuate its transmittance spectrum. More specifically, in the present invention, the eyewear lens attenuates limited amounts of light in at least two visible wavelength regions via controlled, limited blocking filters, wherein the overall luminous transmittance is at least 75%. The at least two controlled, limited blocking filters have their peak blocking wavelengths in the region of 410-500 nm and 530-620 nm, respectively. In a preferred embodiment, the minimum transmittance that occurs within the 410-500 nm region is 55% and the minimum transmittance that occurs within the 530-620 nm region is 65%. In another preferred embodiment, the eyewear lens comprises an anti-reflective coating on its inner surface (the eye-side of the lens).
