2 people are right; it is a result of decreased oxygen to the brain and is called an optical migraine. It usually is a result of vascular spasms or a sudden decrease in blood pressure and is much much more common in females than in males. You should see a doctor to rule intracranial pathology and see if any of your medications could be responsible, if not, then he/she will probably put you on a drug like Imitrex in order to take at the onset of symptoms. Quite frequently, women will go on to develop full-blown migraine symptoms about 15-30 minutes after these flashes and the flashes become a 'prodrome' for a migraine headache. It would be in your best interest to see a doctor and not rely on diagnoses posted on the internet by a bunch of strangers, including myself! Do not be surprised if he/she looks at your heart (ECG) to evaluate your rhythm as well! the causes of migraine are not fully understood as of yet, but appear to be multi-factorial and therefore it is not uncommon to have to try many different medications over time to treat it but occasionally a lifestyle change is sufficient.

I could be exposure to bright lights and that sort of thing. If you weren't staring into your lamp before it happened, white flashes are the first signs of hypoxia (lack of oxygen to the brain). This isn't really a big deal if its once in a while. Sometimes if your rested it can happen but equally if you jump into some type of activity is can also happen. Try yawning when it happens next time and see it it changes to normal. If over time it becomes more frequent or happens over a longer periods of time, I would make an appointment to see a doctor.
extra random knowledge - researchers now assume that the white light that people see in near death experiences is probably this type of hypoxia in its most severe situation

Are you getting them when you stand up too fast? That is caused by a sudden fall in blood pressure.
There is also a thing called an optical migraine- like little floating spots in front of your eyes...but no stars..

Get your eyes tested and explain the symptoms to the doctor.
