Final answer:
EFM is associated with the hazard of missing or perceiving distant objects as farther away, which can be dangerous in situations requiring situational awareness.
Step-by-step explanation:
The hazard associated with Empty Field Myopia (EFM) is that objects in the distance may be missed or perceived as further away than they actually are. This is because with EFM, individuals have a tendency for their eyes to rest in a state of myopia when looking into an empty space without focal points, leading to distant objects appearing blurred. This occurs due to the eyes' lenses being too powerful or the eyeballs being too long causing the rays from distant objects to focus in front of the retina.
Since EFM involves undetected or misperceived distant objects it can pose especially significant hazards when driving or navigating environments where situational awareness is critical.
