Patent ID: 8469512

Claim:
Computer eyewear comprising: first and second lenses, each having optical power in the range from about +0.1 to about +0.5 diopters, each lens providing spectral filtering characterized by a transmission curve, the transmission curve including: a stop band portion positioned between about 320 nm to about 400 nm, the stop band portion reducing transmitted light by at least about 95% on average; a first plateau region positioned between about 420 nm to about 450 nm, the first plateau region transmitting at least about 30% of light on average; a ramp region positioned between about 470 nm to about 560 nm, the ramp region having higher transmission than the first plateau region and reducing transmitted light by about 25% to about 35% on average at about 470 nm to about 480 nm; and a second plateau region positioned between about 570 nm to about 680 nm, the second plateau region reducing transmitted light by less than or equal to about 3% on average at about 640 nm to about 660 nm; and a frame portion disposed about the first and second lenses to provide support.
