A goggle lens comprises a first surface ( 210 ) and a second surface ( 220 ) separated by a thickness ( 230, 240 ) of the goggle lens. The goggle lens is made up of a central region ( 121 ), a first lateral region ( 122 ) on a first side of the central region, and a second lateral region ( 123 ) on an opposite side of the central region. The first surface of the goggle lens is a portion of a first ellipse ( 211 ) and the second surface of the goggle lens is a portion of a second ellipse ( 221 ). The goggle lens complies with at least one of a MIL-PRF-31013 standard, a EA-L-1381B standard, and a FNS/PD 86-20 standard, all of which define particular specifications for impact resistance.
