Abstract
An anti-glare refractor for a luminaire may include an optic body having a light entrance side and a light exit side. The optic body may include a material characterized by an index of refraction. The light entrance side may include a substantially flat surface, and the light exit side may include a plurality of prisms each defined by a plurality of facet surfaces. Each facet surface may have a prism slope angle with respect to the substantially flat surface. The prism slope angle may be in a range from about 5 degrees to about 45 degrees.
