Do symptoms like flashes of light go away quickly?

In brief: Usually

Light flashes mostly are due to changes in the fluids in the back of the eye.
The retina is jostled when this happens and responds with a light flash. You should see your ophthalmologist if this persists more than a day, if there are lots of floaters, if the vision drops, or if you see a grey -veiny veil in the vision. Do not delay as sometimes this can be a retinal detachment.
