Abstract
Eyewear which preferentially transmits light from a liquid crystal display screen using spectral filtering, polarization filtering and/or spatial filtering. The eyewear transmits the relatively narrow red, green, and blue bands of light emitted by the display's fluorescent backlight lamp, while blocking ambient light falling outside of those relatively narrow bands of light. The eyewear can further include polarized lenses oriented at either + or −45 degrees, matching the polarization of the liquid crystal display emission, and thus blocking ambient light not matching that polarization orientation. The glasses can also be tinted except for a central portion matching the shape of the rectangular liquid crystal display screen, and thus preferentially blocking light not originating from the liquid crystal display screen.
