View From Kaleidoscope
How can i fix this vision problem?
I am 23 years old and this has happened about 4-5 times so far, within a couple of months. Out of no where i notice a small kaleidoscope effect in my vision. It doesn't take up my whole view, but a small part of it, it's difficult to explain. It has happen in my friends car, in the middle of class, and infront of the computer. I first thought it was from allergies, but then i thought maybe it's bright lights? im not sure. Has anyone out there experienced the same and can tell me how to stop it?
Also just for your info i have never worn glasses nor have ever had any problems with vision
Sounds like ophthalmic migraines.
Ophthalmic (eye) migraines are quite common and often painless, and thought to be related to changes in blood flow in the brain.
Migraines can be produced by the body's neurological responses to certain triggers such as hormonal changes, flashing lights or chemicals in foods or medications. One result of these triggers may be an intense headache that, if untreated, can last for hours or even days.
During migraine processes, changes also may take place in blood flow to the area of the brain responsible for vision (visual cortex or occipital lobe). Resulting ophthalmic or ocular migraines commonly can produce visual symptoms even without a headache.
People with ophthalmic migraines can have a variety of visual symptoms. Typically you will see a small, enlarging blind spot (scotoma) in your central vision with bright, flickering lights (scintillations) or a shimmering zig-zag line (metamorphopsia) inside the blind spot. The blind spot usually enlarges and may move across your field of vision. This entire migraine phenomenon may end in only a few minutes, but usually lasts as long as about 20-30 minutes.
Generally, ophthalmic migraines are considered harmless. Usually they are painless, cause no permanent visual or brain damage and do not require treatment.
