Flashes and Floaters: Flashing lights are more often not due to retinal detachment but rather from separation of the vitreous (the gel that fills the eye). If a hole is created in the retina from such an event, a retinal detachment may result. Both flashes and floaters are annoying and possibly the sign of a vision threatening problem. Best to have it checked out by and eyemd.

Could be: The symptoms you describe could be from a retinal detachment. If this condition is suspected, you should be evaluated immediately by an eye doctor.

Not temporary...: Usually, when the retina detaches, the loss of vision is there at all times, and gets worse with hours or days. Flashing can be part of a vitreous detachment, which can lead to a retinal tear or detachment. If flashing and temporary blindness in both eyes at the same time, it can be a sign of migraine. If in one eye can be due to loss of blood flow. You need an eye exam! www.2020vision.Com.
