1. A gauge for evaluating fit of an eyewear article, comprising:
- an elongate body having first and second major surfaces and first and second end portions;
a first sphere having a diameter D1 proximate the first end; and
a second sphere having a diameter D2 proximate the second end;
wherein the first major surface is calibrated with a scale extending between the first and second end portions comprising a marked zero location and markings on each side of the zero location, and wherein diameter DI is different than diameter D2, and wherein the markings on each side of the zero location include;
first indicia and second indicia different from the scale markings at opposite sides of the zero location and designating a predetermined minimum distance from the zero location for eyewear coverage in a vertical direction; and
third indicia and fourth indicia apart from the first and second indicia and different from the scale markings, the third and fourth indicia being at opposite sides of the zero location and designating a predetermined minimum distance from the zero location for coverage in a horizontal direction.
