Quick Answer
When making improvised goggles under duress, challenges include limited materials, lack of precise measurements, and the need for rapid assembly to prevent eye damage from snow blindness.
Material Limitations
When creating improvised goggles, the available materials often dictate their effectiveness. In a cold environment, a common material for makeshift goggles is plastic or glass from a broken container. However, these materials may not fit well or provide adequate protection against wind-driven snow, which can exacerbate snow blindness. It’s essential to find or create a seal around the edges to prevent snow from seeping in.
Assembly and Measurement
Improvised goggles often require rapid assembly, which can be challenging, particularly if the person is in a state of distress or has limited dexterity. To mitigate this, it’s crucial to have a clear understanding of the necessary measurements, such as the distance between the eyes and the curvature of the goggles. A common technique is to use a piece of string or twine to mark the distance between the eyes, which can serve as a rough guide for cutting the protective material.
Cold-Climate Considerations
In extremely cold environments, snow blindness can occur within 10-15 minutes of exposure to snow, even in overcast conditions. This highlights the importance of prioritizing eye protection when creating improvised goggles. When selecting materials, consider using a thin, flexible sheet of plastic or a piece of clear glass to reduce wind resistance and prevent snow from seeping in. Additionally, ensure the goggles fit snugly around the eyes to prevent snow from entering through gaps.
