A frame that weighs forty grams feels fine at ten in the morning. By four it has left a line on your nose and a headache behind your ears. The difference between a pair you wear and a pair you carry is about fifteen grams.
We cap every Veyra frame at twenty-seven grams with the lens in. Aeris comes in at nineteen. That number drives every material decision we make, from bio-nylon fronts to the wall thickness of a temple.
You will not notice the weight. That is the point.
