What is is when you get a light zigzag in front of your eye, it is like an ora?

Likely migraine: This sounds like an occipital migraine which causes a zig zag pattern of lights and greying out of certain parts of the vision. If you recover in 5 minutes to 2 hours, then that is almost certainly what you experienced. If it lasts longer or their are permanent visual changes, then see your ophthalmologist.

Ocular migraines!: Ocular migraines are a form of migraines that take place in the occipital cortex (part of the brain that interprets/controls vision). They lack the severe headache as common migraines. The symptoms are usually all or mostly visual and are typically described as flashing of light or ziz-zag lights in the vision. They usually last less than 30 minutes and affect the vision out of both eyes.

Blood pressure probl: This can also be from low or high blood pressure or anemia. See your prinary care doctor.
