Kaleidoscope vision is a short distortion of vision that causes things to look as if you are peering through a kaleidoscope. Kaleidoscope vision is not a standalone condition, but rather a visual symptom of something else. Visual disturbances can occur in one eye or both eyes.
Kaleidoscope vision is commonly caused by migraine headaches. According to the American Migraine Foundation. Kaleidoscope vision is one type of distorted or altered visual symptom that usually occurs before the onset of a visual or ocular migraine.
The visual disturbances of migraines generally last less than an hour, most commonly 10 to 30 minutes. The visual symptoms may or may not be associated with a headache.
An ocular migraine occurs when nerve cells in the part of the brain responsible for vision fire erratically.
As with all other vision changes, it is important to distinguish if kaleidoscope vision may be a warning of a more serious issue. If you experience kaleidoscope vision or any other aura effect, especially for the first time, consult an eye doctor for a comprehensive eye exam.
