Flashes are often perceived as bright flashes of light in the peripheral vision. They are often noticed in the early evening or in areas of low ambient light. Patients may describe them looking a like lightning flashes or a camera flash in the corner of the vision.
Floaters are often perceived as small black shapes that move slowly in the visual field. Some patients describe floaters as appearing like little insects or a spider’s web in the vision. Flashes and floaters are often due to the vitreous jelly in the eye physically separating from the retina at the back of the eye. This is known as a Posterior Vitreous Detachment, or PVD.
