Most of these blind spots happen in one eye, but they can happen in both eyes. Scintillating scotomas: A scintillating scotoma is a visual blind spot that fluctuates between light and dark. Scotoma (pronounced skuh-tow-muh) is the medical term for a visual field abnormality, or a blind spot. This type of scotoma can appear as a dark spot, blurred vision, or a smudge in the center of the eye. If you are not looking and actually moving your head when at junctions for example, you stand the risk of not seeing a narrow object such as a cyclist, because they could be in your blind spot, or even something larger at times. Central scotomas: A central scotoma is a blind sport that occurs directly in the center of the visual field. It is the area of the visual space that corresponds to the area on the retina where axons of the ganglion cells.

Spontaneously, a bright spot will appear in a seemingly-random location within one eye. Since there are no photoreceptors at the head of the optic nerve, it forms a spot of no visual input. This downfall is compensated by two things (which is why we don’t notice blind spots):ġ. This is because we have no photo receptor cells on the optic nerve at the back of the eye covering this area (which sends visual images to the brain). Our eyes have a blind spot at around 20 degrees in each. Sudden blindness (total or near-total vision loss) in one eye is a medical emergency.
