In my years of reviewing gear, I’ve come across many different Gunnar frames (one, two and three, in fact) — computer glasses designed to protect the eyes against the blue light of displays, causing strain and other vision problems. Years after the company first debuted, Gunnars now come in Rx prescription versions, as well as yellow and crystalline lenses.
To this point, they all achieve the desired effect to varying degrees, partly due to how well the frame fits to the face and eyes. So, for me at least, the magic comes from the frame, and not so much the lenses; when in fact, they are the source of the magic that is eye strain reduction.
So naturally for 2015, the lightweight (2o grams) Sheadog frame looked inquisitive to test.
