I've been using Gunnar glasses for years and it makes a real difference for my eyes. This Cruz model doesn't come with 0.2 dioptres, unlike the most of other Gunnars, and after using it for 2 days it appears that my eyes prefer these lenses.
Pro
no magnification with 0.2 dioptres unlike the most of other lenses from Gunnar
anti-reflective coatings on both sides of the lenses
