This is a question that many people have when they experience what is called an “aura.” Auras are most commonly associated with migraines, but they can also be caused by seizures, stroke, and other medical conditions. While the cause of auras is not always known, they are usually not a cause for concern.

Causes of Rainbow Spots
One possible reason for seeing rainbow spots is an issue with the eye called vitreous detachment. This occurs when the vitreous, or jelly-like substance in the eye, starts to pull away from the retina. As the vitreous pulls away, it may form clumps. These clumps can cast shadows on the retina, which the brain interprets as spots of light. In some cases, vitreous detachment can also cause flashes of light.
Other possible causes of rainbow spots include eye conditions such as migraine, stroke, and multiple sclerosis. These conditions can cause visual disturbances known as aura. Aura typically manifests as flashes of light or lines in the field of vision. However, in some cases, it can also cause spots of light.
Rainbow spots can also be caused by certain medications, such as those used to treat bipolar disorder and schizophrenia. These drugs can cause visual hallucinations, which may manifest as spots of light.
If you are seeing rainbow spots, it is important to see an eye doctor to rule out any serious underlying causes. In most cases, rainbow spots are harmless and will resolve on their own.
Diagnosing Rainbow Spots
If you are seeing rainbow spots, it is likely because you are experiencing an issue with your vision. This could be due to a number of things, such as a refractive error, cataracts, or macular degeneration. If you are concerned about your vision, it is best to consult with an eye doctor to get a proper diagnosis.
Treating Rainbow Spots
Rainbow spots, or what are formally called “iridophores,” are cells within the skin of certain animals that reflect light. These cells contain pigment granules that are stacked in layers. When light hits these cells, the light is scattered in a way that creates the colors of the rainbow.
There are a few different theories about why animals have iridophores. One theory is that the colors may help the animal camouflage itself. For example, if an animal has mostly blue iridophores, it may blend in with the sky or water. Another theory is that the colors may be used for communication. For example, some animals use bright colors to warn predators that they are poisonous.
It is still not fully understood why animals have iridophores, but they are an amazing example of the diversity of life on Earth.
Preventing Rainbow Spots
One reason you may be seeing rainbow spots is because you have a condition called macular degeneration. This is when the center of your field of vision starts to deteriorate and you see blank or dark areas. Rainbow spots are also a symptom of migraines, where you may see colorful designs or lights. If you have diabetes, you may experience rainbow spots due to changes in your blood sugar levels. If you think you are seeing rainbow spots because of any of these conditions, you should see a doctor right away. There are treatments available that can help improve your vision.
FAQs about Rainbow Spots
There are a few reasons why someone may see rainbow spots. One reason could be because of a condition called visual snow syndrome, which is a disorder that causes people to see white or black dots in their vision. Another reason could be due to an ocular migraine, which is a type of migraine that can cause visual disturbances. Rainbow spots can also be caused by a condition called entopic pregnancy, which is a rare type of pregnancy that occurs when the fertilized egg implants itself outside of the uterus. Lastly, rainbow spots can be caused by certain medications, such as those used to treat glaucoma. If you are concerned about the rainbow spots you are seeing, it is best to consult with a medical professional to determine the cause.
There are a few possible explanations for why you might be seeing rainbow spots. One possibility is that you have a condition called migraine aura, which is when people with migraines experience visual symptoms before a migraine headache. Aura can include seeing spots or lines, flashing lights, or temporary blindness. Another possibility is that you have a type of eye inflammation called uveitis, which can also cause spots or flashes of light. If you’re concerned about the spots you’re seeing, it’s best to talk to a doctor to rule out any serious conditions.
There are a few additional resources that might be helpful if you’re seeing rainbow spots. The American Migraine Foundation has information about migraine aura, including tips for managing symptoms.
