Fit guide: The NEREUS is sized medium to large. Ziena frames fit by how the frame curves to your face, not by frame measurements, so a measurement alone is not a reliable guide. A good fit seals about 95%, with a small gap left on purpose for ventilation, which helps reduce fogging. Fit can also change in two ways: prescription lenses change how the frame sits, and a new pair arrives at factory-default settings, so you may need to adjust the temple arms and nose pads to get the feel you're used to. Some fogging is normal if you perspire, because the small gap is there for ventilation; an anti-fog wax or gel can help.
