It can be annoying to watch things that aren't there, whether it's pink lights, shadows or elephants, but when people close their eyes, if they have a migraine or even sneeze, they can see a variety of ghostly lights and sparkles .

Inside our eyes is a thick gel, which keeps the eye in good condition.This gel can brush the retina, the part of the eye that creates image it is in our brain .When the brain receives a message from the retina, it interprets it as light.So if there is light or not entering the eye, any retinal stimulation will be interpreted as a spectacle of lights by the brain.

Why does it happen only in those moments?

When you sneeze , pressure is created in the chest and in the head, and with sufficient pressure, the retina can be pushed.If you see stars, it could be due to a pressure in the same eye, or the stimulation of the nerves that have to do with sight. After getting up quickly too, blood pressure can drop, and the brain can be deprived of oxygen, and thus affect the optic nerve.
