it's like when you stare at a lightbulb then close your eyes

[Sundae]

Give it another day then go to your doctor or an optician.
I only get vision occlusion when I am having or about to have a migraine - having it for more than a day could be a symptom of something more concerning.

From here

The reason why you are advised not to ignore symptoms of sudden increase in the number of floaters or flashes of light especially if accompanied by subjective reduction in vision (cloud or curtain in vision) is that these symptoms signify an acute posterior vitreous detachment. There could be an associated retinal tear which can lead to a retinal detachment. Therefore you should have an immediate eye examination to rule out any retinal involvement. A dilated fundus examination is required. Another examination will be performed after 4 to 6 weeks if the first examination is normal.

Although it made me smile because "floater" means something different to me
