    Presbyopic astronauts experienced vision issues with their Space Shuttle suit displays. Fresnel lens strips were mounted on helmets, enabling clear viewing of the alert system without major suit modifications.

    Area of Science:

    • Space exploration
    • Human factors in aerospace
    • Ophthalmology

    Background:

    • Astronauts require clear vision for critical tasks during space missions.
    • Presbyopia, age-related farsightedness, affects astronauts' ability to view close-up displays.
    • Space Shuttle suit visual displays presented acuity challenges for presbyopic astronauts.

    Purpose of the Study:

    • To address the visual acuity challenges faced by presbyopic astronauts.
    • To find a solution for clear viewing of Space Shuttle suit alert systems.
    • To develop a solution within NASA's constraints on suit modifications.

    Main Methods:

    • Analysis of visual acuity problems in presbyopic astronauts.
    • Evaluation of potential solutions considering suit modification limitations.

  • Implementation of Fresnel lens strips on astronaut helmets.

    • Main Results:

    • A practical solution was identified for presbyopic astronauts' visual difficulties.
    • Fresnel lens strips effectively improved the clarity of visual displays.
    • The solution adhered to NASA's constraints, avoiding major suit alterations.

    Conclusions:

    • Mounting Fresnel lens strips on helmets is an effective solution for presbyopic astronauts.
    • This innovation enhances astronaut performance and safety by ensuring clear display visibility.
    • The study demonstrates successful adaptation of technology to overcome physiological challenges in spaceflight.
