Claim 26:
27. An anti-glare refractor for a luminaire having a plurality of light sources, the anti-glare refractor comprising:
an optic body comprising:
a light entrance side comprising a substantially flat inner surface, the substantially flat inner surface being linear over an entire surface that is adapted to receive light rays generated by the plurality of light sources; and
a light exit side comprising an outer surface opposite the linear inner surface and from which the light rays exit the anti-glare refractor, wherein a plurality of prisms are distributed on the outer surface and wherein each prism of the plurality of prisms is defined by a plurality of planar facet surfaces, each planar facet surface having a prism slope angle in a range from about 5 degrees to about 45 degrees with respect to the substantially linear inner surface, wherein each prism comprises an axis passing through an intersection of the planar facet surfaces defining the prism and wherein the prism is approximately symmetrical about the axis,

wherein the plurality of prisms are configured such that, regardless of lateral or vertical positioning of each of the plurality of light sources relative to the anti-glare refractor, an anti-glare distribution from the light exit side remains substantially unaffected.
