Kaleidoscope vision is a symptom of migraine. The brain creates a visual illusion of fractured or bright colors, similar to those a person might see through a kaleidoscope. Migraine can affect vision in many ways.
Shimmering spots in vision
Some people see sparkling lights or blind spots, while others experience kaleidoscope vision. These disturbances usually last around 20 minutes, but they can last from as little as 5 minutes up to 1 hour.
People may also experience kaleidoscope vision due to brain damage or a stroke. This article discusses the causes of kaleidoscope vision, how to get rid of it, and when to see a doctor. When a person has kaleidoscope vision, their brain creates fractured or brightly colored images similar to those a person might see when they look through a kaleidoscope. This visual symptom can occur in one or both eyes but might affect only a small portion of the visual field.
Kaleidoscope vision is just one type of aura. Auras occur in response to a sudden increase in neuronal activity. In most cases, auras are due to migraine. Visual auras can occur with or without headache pain and can affect one or both eyes. Most often, migraine causes kaleidoscope vision. However, more serious causes can also bring on this symptom, such as retinal migraine or a stroke, as the following sections discuss. Migraine and severe headaches affect approximately 1 in 6 adults in the United States.
Current scientific evidence suggests that ocular migraine occurs due to structural abnormalities in the visual cortex. A study examined the MRI data of people who have one-sided ocular migraine. According to the authors, the affected and unaffected sides of the brain showed noticeable differences in the thickness of certain areas of the cortex, or gray matter. The authors suggest that this structural difference may make the visual cortex on the affected side significantly more sensitive to neuronal activity.
Retinal migraine may produce symptoms similar to those of ocular migraine, but these are two distinct conditions. Unlike ocular migraine, retinal migraine occurs in response to reduced blood flow to the eye. Retinal migraine causes visual aura symptoms in one eye only. Auras can last 5—60 minutesafter which people may experience throbbing headache pain.
9 Serious Eye Symptoms to Watch Out For
Stroke occurs when something interrupts or blocks the blood supply to the brain. Potential causes of stroke include:. This type of stroke lasts only a few minutesand the symptoms usually disappear within an hour. That said, they can last up to 24 hours. A TIA can indicate a high chance of having a stroke in the future, so it is important that people inform their doctors if they experience any of the following TIA symptoms:.
If a person suspects a stroke, they should call the emergency services or visit the hospital right away.
Learn more about the signs of a stroke and the signs of a TIA here. The National Institute of Neurological Disorders and Stroke recommend that people seek immediate medical attention if they experience a sudden, severe headache accompanied by any of the following symptoms:.
People may want to consider speaking with their doctor if their headache symptoms worsen over several days. Children and adults over the age of 50 should seek immediate medical attention if they have persistent, recurring headaches. Kaleidoscope vision, along with any other migraine symptoms, will typically go away on their own within an hour.
People can take medications that relieve painful symptoms and prevent migraine episodes from developing in the first place.Visual aura is basically a benign neurological condition that generates simple to complex optical effects. While it may occur on its own, it is known to precede or accompany a migraine. Visual aura may or may not reoccur and this depends greatly on what caused it in the first place.
For someone who has never experienced such a disturbance in vision, an aura can prove extremely worrisome, especially if it is a more complex optical effect. However, even the most simple of visual disturbances can interfere with driving which is why it is recommended to avoid performing complex tasks until the optical effects of a visual aura withdraw. Here is a list of simple and complex optical effects that can be classified as visual aura : 1 Bright flashing or flickering lights.
Scintillating scotoma is a particular type of visual aura. Lines, arcs or flickering lights, either white or colored may occur. Scotoma is a type of visual aura that refers to actual blind spots or dark pathches that start in the scotoma area and slowly spread towards the center of the eye.
This type may come to obscure vision in one eye almost completely. While seizures are rare occurrences, migraines are very likely to occur. Usually, visual auras accompany migraines in the majority of cases. It was a couple of years back and I was driving into town at noon on a beautiful summer day. Almost instantly I started seeing several shimmering, whitish lines which appeared to move across my field of vision.
Visual aurae can have a variety of causes or can be a side effect of another medical problem or condition such as migraines. If you experience both migraines and visual aura, then what is causing your migraines is also causing the visual aurae.
Here is a list of potential triggers of visual aura : 1 Stress and sleep deprivation. These retina cells convert light into signals that help us understand the visual world.
But with time, the vitreous humour the gel-like substance in between the retina and the lens may either liquefy or collapse.Visual Migraine Animation
This means that the vitreous tugs on the retina, causing an innappropriate activation of the photoreceptor cells and subsequent flickers, shimmers or flashes of light. This would explain why loud noises, lifting weights and lack of sleep lead to visual aura. However, the symptoms should last no more than minutes at a time and resolve themselves in days at most. How long do visual aurae last?
Symptoms may last anywhere from 20 minutes to an hour. If they occur for more than days, then a visit to the ophthalmologist is in order to rule out any serious underlying health problem. Unlike visual aurae, eye floaters are particles physically present in the vitreous humour of the eye and usually do not disappear.
Visual auras do not generally require treatment, but rather resolve themselves. But for this to happen, you may need to identify what has been causing these optical disturbances in the first place and learn to avoid it.
If the optical effects are a only a symptom of an underlying medical condition, then it is best to see your doctor for professional treatment. Here are a few tips and tricks that may help prevent and even treat visual auras : 1 Getting enough sleep. Sleeping enough should help relieve strain on the eyes and promote good vision. Because dietary habits play an important part in migraine control and visual auras often accompany migraines, it might be best to monitor your coffee, alcohol, caffeinated beveragesluncheon meats etc.
Similarly, having a balanced diet that supplies essential nutrients such as carotenoid antioxidants, vitamins A and C and dietary minerals is recommended.
Some people report feeling better after taking magnesium supplementsbut research on the subject is lacking.The term "ocular migraine" can be confusing. It generally means a headache that's accompanied by changes in vision. But the term is often used interchangeably to refer to two different conditions: migraine aura, which usually isn't serious, and retinal migraine, which could signal something serious.
Ocular migraine sometimes describes a migraine aura that involves your vision. Migraine auras include a variety of sensations that are often visual. Auras may also include other sensations, such as numbness, that precede or accompany a migraine.
Aura can sometimes occur without a headache. A migraine aura that affects your vision is common. Visual symptoms don't last long. A migraine aura involving your vision will affect both eyes, and you may see:. These symptoms can temporarily interfere with certain activities, such as reading or driving, but the condition usually isn't considered serious.
Ocular migraine sometimes is used as a synonym for the medical term "retinal migraine. Retinal migraine involves repeated bouts of short-lasting, diminished vision or blindness. These bouts may precede or accompany a headache. A retinal migraine — unlike a migraine aura — will affect only one eye, not both. But usually, loss of vision in one eye isn't related to migraine.
It's generally caused by some other more serious condition. So if you experience visual loss in one eye, be sure to see a doctor right away for prompt treatment. Jerry W.
Wait, When Did I Wander into a Funhouse? What to Do About Kaleidoscope Vision
Multiple reflection by two or more reflecting surfaces has been known since antiquity and was described as such by Giambattista della Porta in his Magia Naturalis — Bradley's New Improvements in Planting and Gardening described a similar construction to be placed on geometrical drawings to show an image with multiplied reflection. However, an optimal configuration that produces the full effects of the kaleidoscope was not recorded before In Sir David Brewster conducted experiments on light polarization by successive reflections between plates of glass and first noted "the circular arrangement of the images of a candle round a center, and the multiplication of the sectors formed by the extremities of the plates of glass".
He forgot about it, but noticed a more impressive version of the effect during further experiments in February A while later he was impressed by the multiplied reflection of a bit of cement that was pressed through at the end of a triangular glass trough, which appeared more regular and almost perfectly symmetrical in comparison to the reflected objects that had been situated further away from the reflecting plates in earlier experiments.
This triggered more experiments to find the conditions for the most beautiful and symmetrically perfect conditions. An early version had pieces of colored glass and other irregular objects fixed permanently and was admired by some Members of the Royal Society of Edinburghincluding Sir George Mackenzie who predicted its popularity. A version followed in which some of the objects and pieces of glass could move when the tube was rotated.
The last step, regarded as most important by Brewster, was to place the reflecting panes in a draw tube with a concave lens to distinctly introduce surrounding objects into the reflected pattern. Brewster thought his instrument to be of great value in "all the ornamental arts" as a device that creates an "infinity of patterns". Artists could accurately delineate the produced figures of the kaleidoscope by means of the solar microscope a type of camera obscura devicemagic lantern or camera lucida.
Brewster believed it would at the same time become a popular instrument "for the purposes of rational amusement". He decided to apply for a patent. Soon the instrument was copied and marketed before the manufacturer had prepared any number of kaleidoscopes for sale.
An estimated two hundred thousand kaleidoscopes sold in London and Paris in just three months. Brewster figured at most a thousand of these were authorized copies that were constructed correctly, while the majority of the others did not give a correct impression of his invention. Because so relatively few people had experienced a proper kaleidoscope or knew how to apply it to ornamental arts, he decided to publicize a treatise on the principles and the correct construction of the kaleidoscope.
It was thought that the patent was reduced in a Court of Law since its principles were supposedly already known. Brewster stated that the kaleidoscope was different because the particular positions of the object and of the eye, played a very important role in producing the beautiful symmetrical forms. Brewster's opinion was shared by several scientists, including James Watt. Philip Carpenter originally tried to produce his own imitation of the kaleidoscope, but was not satisfied with the results.
He decided to offer his services to Brewster as manufacturer. Realizing that the company could not meet the level of demand, Brewster gained permission from Carpenter in for the device to be made by other manufacturers. Quackenbush Co. Inkaleidoscope artist Thea Marshall, working with the Willamette Science and Technology Center, a science museum located in the Eugene, Oregon, designed and constructed a 1, square foot traveling mathematics and science exhibition, "Kaleidoscopes: Reflections of Science and Art.
Interactive exhibit modules enabled visitors to better understand and appreciate how kaleidoscopes function. In his Treatise on the Kaleidoscope he described the basic form with an object cell:. Manufacturers and artists have created kaleidoscopes with a wide variety of materials and in many shapes.
A few of these added elements that were not previously described by inventor David Brewster:. Cozy Baker d.
October 19, —founder of the Brewster Kaleidoscope Society—collected kaleidoscopes and wrote books about many of the artists making them in the s through Her book Kaleidoscope Artistry  is a limited compendium of kaleidoscope makers, containing pictures of the interior and exterior views of contemporary artworks. Baker is credited with energizing a renaissance in kaleidoscope-making in the US; She spent her life putting kaleidoscope artists and galleries together so they would know each other and encourage each other.
In a short-lived magazine dedicated to kaleidoscopes— Kaleidoscope Review —was published, covering artists, collectors, dealers, events, and including how-to articles. This magazine was created and edited by Brett Bensley, at that time a well-known kaleidoscope artist and resource on kaleidoscope information. Most kaleidoscopes are mass-produced from inexpensive materials, and intended as children's toys. At the other extreme are handmade pieces that display fine craftsmanship.If we can't tunnel through the Earth, how do we know what's at its center?

Optical Illusions. What is it when you sometimes see a kaleidoscope effect in your vision? Wiki User Yes, you should see a doctor either a neurologist or an ophthalmologist, both optimally -you will likely need a referral from your primary care doctorhowever you are likely experiencing an "ophthalmic migraine".
These peculiarities of the migraine world cause a crescent shaped kaleidoscopic ring in and around the center of your field of vision that can be quite hard to ignore.
If you alternate closing your eyes you can see the abnormality in both eyes, but it may be more noticeable than one or the other. They often come either before a migraine headache sets in, but can exist without ever preceding a migraine.
Generally these episodes last about min and eventually the vision interruption "floats "to one side of the eye or the other and disappears out of the field of vision. If your abnormality is only in one eye and is relatively constant or seems to "float by" in front of your eye a lot this is more likely a "floater". An abundance of these also warrants a trip to the doctor. There is a lot of information about both ophthalmic migraines and floaters in the eye online.
A Google image search will reveal pictures of what others see when they have an ophthalmic migraine. I thought I was going blind.
I went to Eye, Ear, Nose and Throat and the doctor told me it is a migraine. It is called kaleidoscope migraine according to the doctor. Asked in Birds What color do birds see? Birds see like us and sometimes have better vision. Asked in Telescopes, The Difference Between What is the difference between telescope and kaleidoscope?
A telescope helps you see from afar and a Kaleidoscope is for fun. It makes shapes and when you point it at an object, you see it in the shapes and colors in the kaleidoscope.
My father got me one when I was 5 and I still have it. Yes, Glaucoma and Vertigo are linked as they both effect your vision. When you have glaucoma you see dark shadows or your vision is impared when you can not see at all. With vertigo again your vision is effected as your body is not balanced and you can not see clearly as well.
Asked in Eyes Why do you have to have glasses? Sometimes there is something wrong with people's vision, or as they grow older their vision gets worse. Glasses are worn to correct vision, so people can see normally. Asked in Inventions Where is the kaleidoscope used? It is used by sumarines to see in water. I started to see the thread like black string in my right eye. Sometimes its there and sometimes its not. Asked in Insects, Flies What do flies see? No cats cannot see in x ray vision, and sometimes cats can kill by staring, it would make the prey fall dead from fright.
Asked in Science What principle kaleidoscope works?Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy — It may precede a migraine headachebut can also occur acephalgically without headache.
It is often confused with retinal migrainewhich originates in the eyeball or socket. Many variations occur, but scintillating scotoma usually begins as a spot of flickering light near or in the center of the visual field, which prevents vision within the scotoma area. It typically affects both eyes, as it is not a problem specific to one eye. The affected area flickers but is not dark. It then gradually expands outward from the initial spot.
Vision remains normal beyond the borders of the expanding scotoma swith objects melting into the scotoma area background similarly to the physiological blind spotwhich means that objects may be seen better by not looking directly at them in the early stages when the spot is in or near the center. The scotoma area may expand to completely occupy one half of the visual area, or it may also be bilateral. It may occur as an isolated symptom without headache in acephalgic migraine.
As the scotoma area expands, some people perceive only a bright flickering area that obstructs normal vision, while others describe seeing various patterns. Some describe seeing one or more shimmering arcs of white or colored flashing lights.
An arc of light may gradually enlarge, become more obvious, and may take the form of a definite zigzag pattern, sometimes called a fortification spectrum i.
The visual anomaly results from abnormal functioning of portions of the occipital cortex at the back of the brain, not in the eyes nor any component thereof, such as the retinas. It may be difficult to read and dangerous to drive a vehicle while the scotoma is present. Normal central vision may return several minutes before the scotoma disappears from peripheral vision.
Sufferers can keep a diary of dates on which the episodes occur to show to their physician, plus a small sketch of the anomaly, which may vary between episodes. Flickering animation of a scintillating scotoma, where the scintillations were of a zigzag pattern starting in the center of vision, surrounded by a somewhat larger scotoma area with distortion of shapes but otherwise melting into the background similarly to the physiological blind spot.
A depiction of a scintillating scotoma that was almost spiral-shaped, with distortion of shapes but otherwise melting into the background similarly to the physiological blind spot. Scintillating scotomas are most commonly caused by cortical spreading depressiona pattern of changes in the behavior of nerves in the brain during a migraine.
Migraines, in turn, may be caused by genetic influences and hormones. People with migraines often self-report triggers for migraines involving stress and a wide variety of foods. The Framingham Heart Studypublished insurveyed 5, people between ages 30—62 and found that scintillating scotomas without other symptoms occurred in 1.
The study did not find a link between late-life onset scintillating scotoma and stroke. Symptoms typically appear gradually over 5 to 20 minutes and generally last less than 60 minutes, leading to the headache in classic migraine with aura, or resolving without consequence in acephalgic migraine.
Typically the scotoma resolves spontaneously within the stated time frame, leaving no subsequent symptoms, though some report fatigue, nausea, and dizziness as sequelae. The British physician John Fothergill described the condition in the 18th century and called it fortification spectrum.Back to Health A to Z.
These episodes can be frightening, but in most cases they're harmless and shortlived, and eyesight goes back to normal afterwards. It's unusual for an episode of vision loss to last longer than an hour. The same eye is affected every time in almost all cases.
Vision may slowly become blurred or dimmed, or there may be flashes of light. Some people see a mosaic-like pattern of blank spots scotomaswhich enlarge to cause total loss of vision.
Use our directory to find opticians or find GP services. It's important to see an optometrist or medical doctor urgently if you suddenly lose your eyesight, particularly if it occurs for the first time. There are other more serious causes of sight loss that doctors will want to rule out.
If you manage to see a GP or optometrist during an attack, they may be able to see the decreased bloodflow to your eye using an instrument called an ophthalmoscope. In this case the GP or optometrist may be able to make a confident diagnosis of retinal migraine. You may be referred to an eye specialist for tests to rule out other more serious eye diseases or stroke. Retinal migraine is caused by the blood vessels to the eye suddenly narrowing constrictingreducing the blood flow to the eye.
Afterwards the blood vessels relax, bloodflow resumes and sight returns. Usually there are no abnormalities within the eye and permanent damage to the eye is rare. Treatment for retinal migraine usually just involves taking pain relief for any headaches and reducing exposure to anything that might be triggering the retinal migraine. However, there's still a lack of research about the best way to treat or prevent a retinal migraine. Permanent vision loss is rare.
