What does it mean when you close your eyes and see white dots?
Phosphenes are the moving visual sensations of stars and patterns we see when we close our eyes.
They are thought to be caused by the inherent electrical charges the retina produces even when it is in its “resting state” and not taking in a ton of information and light like it does when our eyes are open..
Can brain tumors cause eye flashes?
Some brain tumors can cause visual or auditory disturbances. 2 Problems with vision can include seeing flashing lights, double vision, blurring, and loss of vision.
Can dehydration cause eye flashes?
Dehydration, stress, lack of sleep, caffeine and certain foods are typical triggers for ocular migraines. When someone describes their flash stemming from only one eye and it is a quick flash usually only seen in the dark almost like a flash from a camera then I often attribute this to the vitreous gel.
What does it mean when you see flashing lights in your eyes?
When the vitreous gel inside your eye rubs or pulls on the retina, you may see what looks like flashing lights or lightening streaks. You may have experienced this sensation if you have ever been hit in the eye and see “stars.” These flashes of light can appear off and on for several weeks or months.
Are eye flashes serious?
While typically harmless, floaters that occur suddenly and are accompanied by flashes of light or impaired vision can signal a potentially serious eye problem, particularly among older adults.
What are the warning signs of a detached retina?

When should I worry about eye floaters?
If you notice a sudden increase in eye floaters, contact an eye specialist immediately — especially if you also see light flashes or lose your peripheral vision. These can be symptoms of an emergency that requires prompt attention.
Can high blood pressure cause flashing lights in eyes?
Low blood pressure can cause people to see stars or specks of light, particularly if they change position quickly. An example would be standing quickly from a sitting position or rising quickly after stooping or bending over. Pregnancy related high blood pressure (pre-eclampsia) can also cause light flashes.
Can stress cause eye flashes?
This is called a migraine aura. Eye flashes from a migraine aura may appear like jagged lines or cause a person’s vision to appear wavy. As stress can be a trigger for some migraine attacks, it’s possible there’s a connection between stress, migraine, and eye flashes.
What do flashing lights look like with retinal detachment?
This is called posterior vitreous detachment (PVD). It is very common and more likely to happen as you get older. As the vitreous pulls away from your retina you may see this as a flash of light in one or both eyes, like small sparkles, lightning or fireworks.
How do you get rid of flashes in your eyes?
The easiest way to get rid of flashes and floaters in the eye, at least temporarily, is to move your eyes up and down (this is more effective than moving your eyes side to side). This movement shifts the fluid around in your eye and moves them out of your field of vision.
Are eye flashes an emergency?
If you suddenly have more floaters than normal or are experiencing flashes (bursts of light across your field of vision), you should reach out to your eye care provider right away.
Do flashes always mean retinal detachment?
Flashes are brief sparkles or lightning streaks that are most easily seen when your eyes are closed. They often appear at the edges of your visual field. Floaters and flashes do not always mean that you will have a retinal detachment. But they may be a warning sign, so it is best to be checked by a doctor right away.
Are occasional eye flashes normal?
“Floaters” and flashes are a common sight for many people. Floater is a catchall term for the specks, threads, or cobweb-like images that occasionally drift across the line of vision. Flashes are sparks or strands of light that flicker across the visual field. Both are usually harmless.
