A member asked:

Every now and then my vision gets a blurry ring and most times my whole vision will go black for a couple of minutes after. why? it comes back later.

A doctor has provided 1 answer

See below: It could be an ocular migraine. It is caused by a spasm of a blood vessel in the vision pathway. Avoid caffeine, cheeses, decongestants and go see a doctor for confirmation.
