ABSTRACT:
System, method and apparatus wherein eyewear is provided particularly suited for use in conjunction with luminescent displays such as visual display terminals and which serves to improve operator performance and reduce asthenopia. The eyewear includes a forward frame portion having a centrally disposed bridge section and right and left temple pieces extending from the frame portion. The frame supports a clear optical region dimensioned for intercepting lines of sight substantially only within the inferior field of view of the user's eyes and a translucent region intercepting and blocking lines of sight directed substantially outwardly from the mid pupillary position of the user's eyes within the superior field of view. Preferably, the clear optical region is pigmented to define an optical filter and this filter preferably is selected having a pigmentation in the yellow portion of the visible spectrum.
