What is the differnce of Scheerer's phenomenon and visual snow?

[nec209]

I thought Scheerer's phenomenon was is the appearance of tiny bright dots moving quickly along when looking into blue light or very bright out side?

 

And visual snow is like snow like appearance does not matter if it is bright or not.There is no cure for Scheerer's phenomenon and visual snow yet .

 

The dots are due to the white blood cells that move in the capillaries in front of the retina from what I understand.

 

 

my last question I thought digestive tract was 5 to 8 hours ? For past 3 days I got a upset stomach 2 hours after eating the same food.

 

I thought 2 or 3 hours the food would not even be in the small intestine yet that lone the bigger intestine ?
