Most unexplained blackouts are caused by syncope Many people, including doctors, assume that blackouts are due to epileptic seizures, but much more commonly they are due to syncope (pronounced sin-co-pee) – a type of blackout which is caused by a problem in the regulation of blood pressure or sometimes with the heart.
What causes sudden loss of sight?
Common causes of sudden vision loss include eye trauma, blockage of blood flow to or from the retina (retinal artery occlusion or retinal vein occlusion), and pulling of the retina away from its usual position at the back of the eye (retinal detachment).
How do you fix flash blindness?
Treatment for flash burns may include: dilating drops – these are sometimes used to relax the eye muscles, which in turn eases pain and allows your eyes to rest and heal. Your pupils (the black part of the eye) will look bigger than normal. This effect lasts several hours to a few days.
What do blind people see?

Is flash blindness permanent?
The bright light overwhelms the retinas of the eyes and generally gradually fades, lasting anywhere from a few seconds to a few minutes. However, if the eyes are exposed to a high enough level of light, such as a nuclear explosion, the blindness can become permanent. Flash blindness may also occur in everyday life.
