FIELD OF VIEW
The field of view from the Optic Nerve Nastek is at the top of the class, but that should be expected from a wide-angle goggle with a cylindrical lens. Our in-house test yielded a 170 degree field of view, which was among the top performers. The nose cut obstructed the view when looking down, but only slightly more than other goggles tested.

FIT & COMFORT
Of all goggles tested this year, the Nastek has the largest nose cut, so this is the right goggle frame for larger faces and noses. However, when paired with a medium-sized face, it left “finger-sized” gaps near testers’ temples, allowing wind and snow to come in. They were also tested with prescription glasses under the goggles, and worked great. We paired them with five different helmets, and found no major issues with a goggle gap.

ANTI-FOG POWER
No fogging occurred in the Nastek lenses when tested in the relatively dry climate of Colorado. Out of the many goggles tested, the Nastek was one of the last lenses to steam up in our in-house steam room test.

LENS QUALITY
The Optic Nerve Nastek Saturn has a great lens, both in function and in look. We experienced no distortion at the edges. They worked great in most low light conditions, with the exception of cloudless days with tons of glare coming off the snow. It was notable that after several days of use, however, these lenses didn’t scratch at all.

FEATURES
The strap was easy to adjust and it stayed in place on and off helmet due to the three lines gummy silicon that go all the way around the inside of the strap. The strap is one continuous piece, and the elastic was just stretchy enough for moving them from face to forehead without any issues. It comes with a lightweight bag and a semi-hard shell case, which we loved. There are no other lens options.
