  Chapter 17: Aeromedical Factors › Vision in Flight › Night Blind Spot

  Night Vision There are many good reasons to fly at night, but pilots must keep in mind that the risks of night flying are different than during the day and often times higher. [Figure 17-16] Pilots who are cautious ... educated on night-flying techniques can mitigate those risks and become very comfortable and proficient in the task. Night Blind Spot It is estimated that once fully adapted to darkness, the rods are 10,000 times more sensitive to light…

  Chapter 17: Aeromedical Factors › Vision in Flight › Night Vision Protection

  This precaution increases the rate of dark adaptation at night and improves night visual sensitivity. Oxygen Supply Unaided night vision depends on optimum function and sensitivity of the rods of the retina. Lack of oxygen to the rods (hypoxia) significantly ... their sensitivity. Sharp clear vision (with the best being equal to 20–20 vision) requires significant oxygen especially at night. Without supplemental oxygen, an individual’s night vision declines measurably at pressure altitudes above 4,000 feet. As altitude increases…
