- Caused by the effect on the retina of the initial brilliant flash of light produced by the explosion
- Victims DO NOT have to be looking at the detonation site, as reflected/diffracted light is sufficient in many cases.
- Victims driving at the time of the event, will be unable to see, potentially causing large numbers of traffic accidents.
- During daylight, flash blindness does not persist for > about 2 minutes, but is generally seconds.
- At night, when the pupil is dilated, flash blindness will last longer.
- Partial recovery may be expected within 3-10 minutes in daylight, longer at night.
