Pyramex Fortress is a line of lightweight sports-styled safety glasses that contour closely to the face to provide maximum protection. These Pyramex Safety Glasses have an adjustable nose pad that provides a comfortable fit for a broad range of bridge sizes. The Pyramex Fortress Eyeglasses have vented lenses that allow air flow to prevent fogging of the safety glasses. Straight back rubber coated temple tips give the Pyramex Fortress a comfortable fit. This Pyramex design exceeds ANSI Z87.1-2003 High Impact Requirements.
