A mechanical iris diaphragm has been specifically designed to convert these readily-available goggles, into a novel pair of Steampunk goggles. Perfect for Steampunk events, fancy dress, or even Halloween.

The 6-leaf iris is fully functional, with an aperture range of approximately 7 – 28 mm.

Available with a single iris, or one for both eyes.

Custom orders also accepted, if you want to upgrade to the 12-leaf iris, or would like a different colour iris.
