Achieve a flawless 1:1 fit with our G.DIA 12.1mm to 12.5mm Collection. This range sits right in the "True-to-Size" category. Since the average human iris is roughly 11.5mm to 12.0mm, these lenses provide just enough coverage to mask your natural eye color completely while adding a tiny, barely-there definition to the rim. If you want eyes that look naturally distinct and vibrant without the obvious appearance of wearing circle lenses, this is your ideal size.
