Causes of flashes in your vision. As the vitreous âgelâ within your eye shrinks, it may pull on the retina (the focusing surface at the back of your eye). If the retina is peeled away from the back of the eye, it can cause flashes of light in your vision to occur. A retinal tear or detached retina is a serious and potentially sight-threatening condition.
The shrinking vitreous can pull on the retina as it detaches, stimulating the nerves and causing light flashes. PVD is the most common cause of the sudden appearance of eye light flashes, occurring in roughly 50 percent of people with the condition. Floaters also occur frequently with PVD. Despite the rather scary name, PVD is a common age-related eye change that typically develops after age 60. People who are nearsighted have an increased risk for the condition. Vision loss rarely occurs with PVD and the light flashes usually disappear within 1 to 3 months.
