I see some shimmering in my vision”. This is a common phenomenon we call an ocular migraine. It typically looks like a kaleidoscope or a jagged “C” shape at the edge of your vision.
It can also be a loss or dimming of part of your vision in one eye, lasting 20-30 minutes. Some people will get a headache afterward, some will not. While it’s not completely understood what causes an ocular migraine, similar triggers to migraine headaches have been associated: with caffeine, stress, etc.
Mild over-the-counter medications can help with headaches such as acetaminophen or ibuprofen. Other prescription medications may be prescribed by your doctor.
If you experience these symptoms, it’s important to be evaluated by your eye doctor. These symptoms can overlap a transient ischemic attack (TIA) including a loss of vision in one or both eyes and headache. It can also overlap symptoms of a retinal detachment which includes loss in part or all of vision, usually in one eye.
