## Dim and Bright Lighting
- Dim lighting requires time (~30 min) for our eyes to adjust
- Bright lights seen for longer than 1 second impair night vision
- Red light benefits and drawbacks
- Consider covering one eye for white light use^[Like a pirate! Maybe we should all start wearing eye patches at night]
## Altitude Impact
> [!quote] From [[AFH Ch11]]
> Inflight exposure to low barometric pressure without the use of supplemental oxygen (above 10,000 feet during the day and above 5,000 feet at night) can result in [[hypoxia]], which impairs visual performance.
