A precision-made Dallmeyer Iris diaphragm.

[Historic Vids @historyinmemes]

Centuries ago, approximately 800 years prior, the indigenous Inuit and Yupik communities residing in Alaska and northern regions of Canada ingeniously crafted small apertures on ivory and antler materials to fashion snow goggles. This innovative creation served the purpose of reducing eye fatigue and protecting against the harmful effects of snow blindness caused by ultraviolet (UV) radiation emanating from direct sunlight as well as its reflection.
