Just a community for everyone to share artifacts, reconstructions, or replicas for the historically-inclined to admire!

Generally, an artifact should be 100+ years old, but this is a flexible requirement if you find something rare and suitably linked to an era of history, not a strict rule. Anything over 100 is fair game regardless of rarity.

The effectiveness of Inuit snow goggles lies in their ability to combat the unique challenges of the Arctic environment. Here’s a detailed breakdown of their functionality:

Reducing Light Exposure: The narrow slits drastically reduce the amount of light entering the eyes. By limiting the light intake, the goggles prevent the retina from being overwhelmed by the intense reflections off the snow and ice.

Blocking UV Rays: Snow reflects up to 80% of UV rays, which can cause severe eye damage. The slit design of the goggles blocks a significant portion of these harmful rays, protecting the eyes from potential injury.

Improving Focus and Depth Perception: The slits also help in focusing light more precisely onto the retina, enhancing depth perception and contrast. This is particularly useful in the flat, monochromatic landscapes of the Arctic, where distinguishing between different features can be challenging.

Ventilation and Anti-Fogging: The simple design of the goggles allows for natural ventilation, preventing fogging. Unlike modern goggles, there are no lenses to fog up, ensuring clear vision at all times.
