Flashes and Floaters
Small specks, spots and flashes of light in the field of vision are called flashes and floaters. Caused by changes in the fluid of the eye, flashes and floaters are generally not causes for concern. Flashes can also occur with migraine headaches.
In some cases, floaters and flashes may be the symptoms of a more serious eye problem, such as retinal tear, or retinal detachment. The retina tears as the internal eye fluid shrinks and pulls away from the retina, causing bleeding that appears as a new set of floaters. Retinal tears require immediate medical attention to prevent retinal detachment which could result in partial or total loss of vision.
