A space visor is a critical component of a space helmet, essentially acting as a protective shield for the astronaut's eyes and face. Based on descriptions, a space visor is often a triple lens shield, designed to offer multiple layers of protection against the harsh conditions of space.
These protective layers serve several vital functions:
- Visual Protection: The visors protect the astronaut's eyes and the helmet's main faceplate.
- Thermal Protection: They shield against extreme temperatures, both heat and cold.
- Micrometeorite Protection: The layers are built to withstand impacts from tiny particles speeding through space.
Specifically, a space helmet might feature multiple visors stacked together. For example:
- There could be two over-visors made of materials like Lexan.
- These Lexan over-visors provide crucial micrometeoroid and thermal protection for the primary faceplate.
- Additionally, one visor might be specially treated, such as being gold tinted, specifically to provide glare protection from the intense sunlight encountered in orbit or on the lunar surface.
In summary, a space visor is a multi-layered lens system integrated into a space helmet, providing essential environmental protection and enhancing the astronaut's visibility and safety.
