Flashing lights after exercise

Coronavirus: Check your symptoms. Are you seeing "light" flash before your eyes lately? Light flashes, sometimes called floaters, are a specific type of eye problem that typically indicates a much deeper issue with the eye [1]. If you're experiencing flashing lights in your vision, it can likely be described by the following [2,3]. If any of these flashing lights in vision symptoms occur, you need to see an ophthalmologist who can diagnose your specific eye problem so you can get the most efficient treatment [1,2].

It is filled with a jelly-like substance called the vitreous gel [1]. From time to time, some of this substance breaks loose within the inner rear portion of the eye and we will see these floating cobweb-like substances in our field of vision. It is normal for this to occasionally occur. Although it appears as if these floating objects are in front of the eye, they are really floating within the vitreous layer of the eye [3].

Migraines can also cause flashes of light to appear in the eye. With migraine headaches, people will often experience floaters or flashes of light that look like heat waves or jagged lines. These can appear in both eyes and can last a long time — up to 20 minutes or more. A headache that occurs right after these flashes of light is a typical migraine headache.

However, sometimes people experience these flashes of light with no headache. When this occurs, it is called an "ophthalmic migraine" or "migraine without headache" [3]. If you begin seeing these floaters often, there could be a more serious cause of these flashes of light, such as a torn retina.

A torn retina occurs when the retina tears as a result of the vitreous gel pulling away from the back of the eye. This is a serious problem as it can lead to an even more severe type of eye problem called retinal detachment [4].

This list does not constitute medical advice and may not accurately represent what you have. A cataract is when the lens, a crystalline structure in the eye that normally allows light into the eye, becomes cloudy. Symptoms of a cataract include blurry vision, difficulty seeing at night, glare, difficulty discerning colors, and increased nearsightedness.Bright lights and too much exercise are well-known migraine launchers, but the latest study hints that sufferers may not be as sensitive to these triggers as previously thought.

Researchers report in the journal Neurology that commonly suspected migraine triggers might not be responsible for a hurting head after all. Unlike previous studies of migraine triggers, in which sufferers were asked about what conditions or situations preceded a headache, the scientists exposed 27 migraine patients in a lab to flashing lights, intense exercise or a combination of both to provoke a migraine with aura, a type of headache accompanied by often debilitating visual disturbances.

Only a handful of subjects experienced any sort of migraine, and those who did had exercised, suggesting that bright lights may not be to blame. The participants ran or used an exercise bike at maximum effort for an hour, while researchers used a combination of lamps, flashes and other visual stimuli to mimic light disturbances for up to 40 minutes in order to study the combined effect of light and exercise.

Stephen D. Silberstein, a professor of neurology at Thomas Jefferson University and the director of the Jefferson Headache Center who co-wrote an accompanying editorial for the study, suggests that some of what people think are triggers may actually be symptoms of migraines instead.

Does that mean chocolate triggers the headache? Distinguishing between triggers and symptoms is challenging, not just for those who study migraines but for patients as well. Silberstein says there are some known triggers, such as certain odors, hunger, chemicals in alcohol and hormonal changes linked to menstruation, but that other factors may fall somewhere between an actual trigger and a symptom.

How can patients tell? Both Olesen and Silberstein say there are a number of factors that determine whether these suspected triggers will actually lead to an attack. Patients likely have individual thresholds that vary from day to day and from environment to environment: some days your brain is less vulnerable to certain triggers, while on other days the conditions might be right for a migraine.

Stressfor example, is one of the most commonly reported migraine triggers, and bright lights and exercise may simply be markers for when stress levels are high.

Similar to the placebo effect, how patients think about migraines will often influence how they experience them. Because the study was conducted in a lab setting, the exposure to triggers may not accurately replicate the conditions that launch a real-life headache. For example, if a migraine strikes after you exit a dark movie theater and walk into bright light, it could be the sudden contrast from the darkness of the theater that made the light problematic. Or, you might have been hungry or sleep-deprived before being exposed to a bright light, which would still make the light a trigger, albeit one of a combination of factors that prime your brain for the headache.

The findings hint, however, that some long-held truths about avoiding triggers that can induce migraines with aura may be outdated. That suffering may be worth it in the long run.Billytogan over a year ago.

Guest over a year ago. Couldn't find what you looking for? Billytogan over a year ago Thanks for taking you time and reading this. I have been seeing these flashing lights in my vision. Now they come and go and this is what I have noticed tirggers them. They are blackish when looking at a white wall and they appear whitish when looking at a computer or tv screen They are not there and then I blink and they appear like the after image of a camera then fade away QUICKLY. Also When I move my eye from looking at one this to the other they appear then disappear.

They only last for a seconds after I blink then come back when I blink. If its in my right eye it come when I blink my right eye.

If its in my left it comes when I blink my left. This lasts from 1min to 5 mins I dont actually see the flash for 5 mins but this is how long it happens when i blink then it stops after that I have TMJ could that be anything to do with it? I went to an eye doctor and they said no retinal detachment. I have major anxiety I had a cat scan of my neck for lumps turns out just swollen lymph node.

My parents have had it up the hear with tests because I am on 20 but I still worry its something with my blood flow. It is just from eye strain or should I go and have yet another test for something. You need too get some medication so you don't worry so much. We all have flashing lights when we close our eyes - as it is THAT what our eye sees. HAve you ever seen a computer on tv. It shows it going down and down, so that is why we don't blink, the brain thinks we are.

So we get eye strain. Honestly hon, you do need to get some medications too help you with ALL of this anxiety. And STOP smoking dope, it is a depressent, and can lead to paranoia. Tray and not be on the computer so much and get out and get some fresh air. Like I said earlier, if you keep researching every little thing, you will think you have something worse.

And you ahve had every test under the sun. So ask for some help, and I promise you, all this worry will be a thing of the past soon.

I'm sure if you talk to your parents about what I am saying, they will agree with me, and try and get you some help OK? And don't feel bad about it, is is growing and growing the amount of people with Anxiety or panic attacks.

Good luck and health! Guest over a year ago I think i had the same problem with bill I just got this problem about a moth ago. I can see kind of camera flash light on my right eye when i blink my eyes. This happens once in every 30 - 60 minutes. Also, i spend most of my time in front of the computer as well. Just that i don't smoke weed.Many conditions cause light flashes in the eye, known medically as photopsia.

Seeing phantom light flashes is sometimes harmless, but this symptom might signal a serious disorder requiring urgent medical treatment. Photopsia most commonly originates within the eye itself, but can also occur due to disorders affecting visual nerve pathways in the brain.

See you doctor if you experience light flashes to determine the cause and appropriate treatment, if needed. An occasional light flash in the eye can occur in healthy people without eye or medical problems. Most people discover during childhood that pressing or rubbing the eyes often elicits the appearance of sparkling or flashing lights, colors and shapes. This occurs because pressure on the eye mechanically stimulates the nerves of the retina, the vision-perceiving area at the back of the eye.

Some people also experience brief photopsia with rapid eye movements. In an otherwise healthy young adult, these light flashes are typically harmless and rarely indicate an underlying eye or medical disorder. The vitreous is a gel-like substance that fills the back portion of the eye. Tiny fibers loosely attach the vitreous to the retina. As you age, the vitreous shrinks and can partially or completely detach from the retina, a condition called posterior vitreous detachment PVD.

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 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. However, an eye exam is needed to check for complications, such as vitreous bleeding or a retinal tear. A retinal tear describes a tear in the retina of the eye. Other causes of retinal tears include eye injury or surgery, and diabetic eye disease, among others. When a retinal tear occurs, the vitreous can leak through the tear and lift the retina from the back of the eye, a condition called retinal detachment.

A retinal tear, with or without detachment, commonly causes sudden flashes of light in the affected eye 3. Other possible symptoms include floaters, spots or shadows, and blurry vision or partial vision loss.

Urgent medical care is needed to prevent permanent vision loss with a retinal tear or detachment 3. Treatment options include surgery, laser treatment and cryopexy, a freezing technique that seals the retinal tear. Phantom light flashes can occur for a number of other reasons. For example, people with migraines who experience an aura often report flashing lights in one or both eyes as the headache develops. Less commonly, light flashes can occur without a subsequent headache, a condition called an ocular migraine.

Other potential causes include: -- head trauma -- eye or brain tumor -- optic neuritis, or inflammation of the eye nerves -- macular degeneration, a disease of the retina -- low blood pressure or low blood sugar -- transient ischemic attack, or a mini-stroke -- medication toxicity, such as:.

I got so tired then any time I closed my eyes I saw these lights inside my head. I see these lights almost every time that I run fast or some thing like that. What are they and where do they come from? This is a common phenomena which most of us come across.

Seeing flashes of light, stars and other shapes in the eyes occur when the body goes through stressful activities. For example while you are climbing the blood flow will be more to other prominent parts like hands and lower waist so brain and eyes will get less supply of blood as well as nutrients. Hence those flashes or stars are visible to us. This phenomena is called "Phosphene" and a phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye.

Phosphene is "seeing stars", from a sneeze, laughter, a heavy and deep cough, blowing of the nose, a blow on the head or low blood pressure such as on standing up too quickly or prior to fainting.

It is possible these involve some mechanical stimulation of the retina, but they may also involve mechanical and metabolic such as from low oxygenation or lack of glucose stimulation of neurons of the visual cortex or of other parts of the visual system.

So to summarize this thing, we should have enough nutrients, water supply to the body whenever we come across stressful activities. Phosphenes are temporary stuff which do not harm eyes. It could be posterior detachment of the vitreous humor. Stress on the optic nerve caused by motion of the vitreous humor inside the eye can lead to the sensation of lights.

And since the nerve is circular, you see a pattern of circular light. Normally its not serious, and many people experience it as age progresses. If you are not hydrating well during your climbing that might also be aggravating it. To be safe you should have an eye doc check you out though since there is slight risk it could lead to retinal detachment.

Have you ever spotted a small speck, dot, or squiggle floating in the air, only to have it flit away when you tried to look at it directly? Or have you noticed flickering lights or lightning streaks that you knew weren't really there? If so, you are one of many people who have experienced the common vision phenomenon known as eye floaters and flashes. The majority of people — 7 out of every 10, in fact — will experience eye floaters and flashes at some point in their lives. They are a normal part of the aging process and, most of the time, not considered a medical problem.

However, a rapid onset of many eye floaters and flashes could indicate that a retinal tear has occurred; if not treated immediately, this could cost you your eyesight.

Our eyes are filled with a clear substance known as vitreous gel that helps the eyeball keep its shape while allowing light to pass through to the retina; the retina is located on the eye's back wall and contains nerve cells that perceive visual signals from light. Eye floaters and flashes are caused by changes in the vitreous gel that occur as we get older. Eye floaters occur when the vitreous gel thickens or shrinks due to aging, causing particles to form in the gel.

These particles block the light passing through your eyecasting shadows on the retina. The shadows are seen as floaters, which can be created by:. Eye flashes result from thickened vitreous gel pulling and rubbing on the retina, causing visual effects that look like lightning streaks or light flickers.

These flashes may appear off and on for a few weeks or months, but normally fade over time. If you see flashes accompanied by floaters, you most likely are experiencing PVD. Flashes also can be caused by an oncoming migraine headache. In these instances, the eye flashes often will look like jagged lines or heat shimmers that last between 10 and 20 minutes.

Eye floaters and flashes caused by the vitreous gel are most visible when you are looking at a plain, light-colored background.

Close one of your eyes and look at an empty wall, a blue sky, or a white background on a computer screen. If you see a squiggle, dot, or other shape flitting around, then you have found an eye floater. Eye floaters and flashes normally require no treatment. Flashes usually fade away, and over time most people don't notice floaters as often because the brain learns to filter out the visual interference.

An annoying floater in the center of your vision sometimes can be relieved by rolling your eyes around, which swirls the vitreous gel in the eyeball and gets the floater to move away.

A surgical procedure called vitrectomy removes the vitreous gel from the eye and replaces it with saline solution, but it is a major procedure that normally is not considered worth the risk. The tugging from the vitreous gel can sometimes cause a more serious medical condition in which the retina tears and detaches from the eye. If this occurs, you could partially or completely lose your vision in that eye.

Symptoms of retinal detachment include:. Surgery is the only treatment for retinal detachment, and time is of the essence in preserving your vision.Our eyes are one of the most important organs in the body, as they give us the ability of sight.

However, there are many medical conditions that can compromise our vision, with some resulting in a decreased ability to focus or the loss of vision itself. Most disorders that affect the eye will likely affect vision in some way, with random floaters or flashes being relatively common. These may present as flashes of light in the corner of the eye, flashes of light in the peripheral vision, or even as flashes of light in both eyes.

Floaters are a general term used to describe specks, threads, or cobweb-like images that occasionally drift across the line of vision. Flashes are strands of light that flicker across the visual field that is usually enhanced by these floaters.

Both are considered harmless occurrences but are signs of potential future problems in the eye, especially when they happen suddenly and often.

About one-quarter of people has some vitreous shrinkage, developing floaters by their 60s. This percentage rises to about two-thirds in year-olds. Floaters can also be appreciated in those who have had previous eye surgery, or eye injuries, and in those who have had long-term diabetes.

Floaters are generally well tolerated, but some may complain they interfere with reading or overall vision. Migraines and flashes auras often present together. These flashes appear in a similar manner to floaters, looking like flickering lights, but often only on one side of your vision and in a jagged pattern. It will most likely obscure the vision on one side and usually go away after 10—20 minutes. It could also be followed by a headache.

This type of flash may be caused by a migraine, as it can result from a spasm of blood vessels in the brain. When the vitreous fluid in your eye rubs or pulls against the retina, it may present itself as a flash of light or lightning streaks. This sensation can also be experienced if you have been stricken in the eye and see a bright light before regaining vision.

Older individuals may experience flashes on or off for several weeks or months and it may be a complication of a pre-existing disease like diabetes. It is important to see your doctor if you experience sudden episodes of flashes to get a more precise diagnosis. The following are some symptoms that should prompt you to see a medical professional, such as an optometrist:. Photopsia is the symptom of seeing flashes of light and is essentially harmless, but it may be a sign of more serious complications elsewhere in the body that require urgent medical attention.

Rapid eye movement might accompany episodes of flashes as well. Photopsia is usually seen in those of advanced age, as it seldom occurs in young and healthy adults. The following are some conditions that may cause flashes to occur:. The vitreous fluid is a gel-like substance that fills the back portion of the eye.

Tiny fibers loosely attach the vitreous to the retina. As we age, the vitreous shrinks and can partially or completely detach from the retina. This shrinkage can pull the retina as it detaches, stimulating the nerves of the eye and producing what is perceived as flashing light. This condition typically occurs in your 60s, with those who are nearsighted having an increased risk. A tear in the retina of the eye that causes vitreous to leak through the tear and lift the retina from the back of the eye.

It is known to affect approximately 14 percent of those with PVD. Retinal tears may occur due to eye injury or surgery, but could also be a result of diabetic eye disease.

It typically presents as flashes of light in the affected eye, with the possibility of seeing floaters, spots, or shadows.

Healthy individuals may also experience flashes that are generally harmless. If you were to rub your eyes, it would elicit a similar appearance of sparkling or flashing lights, colors, and shapes.

This happens because as we press on the eyes, it puts pressure on the optic nerves of the retina and the vision perceiving areas of the eye. A doctor can give you a precise diagnosis of reasons behind your eye flashing.
