how long do visual seizures usually last? can they last just for a split second, or are they usually longer?

Visual migraine: You are probably talking about visual migraine, a condition of the circulation in the occipital lobes. These usually last from 5 minutes to at most 2 hours. If you have photic flashes lasting a second or two, it is probably a retinal/vitreous interaction problem and not seizures.

Average: The average for a GTC is around 2.5 minutes. 3 is common. 4 is getting pretty long. 5 is a medical emergency. Recovery takes much longer, of course.
