Bending down for a while and then standing up I think would produce a sudden drop in blood pressure.
Remindes me of hyperventilating years ago. That'll produce lights!
yes, i always had this low pressure and whenever i would bend to get something from the floor, and suddenly stand up again, i would feel this white little lights blurring in the eyes! The sensation of a buzzing at the level of the third eye but above the ears was felt. When the buzzing would stop, then the eyes would recover the vision. The doctor explained it being the blood pressure effect due to suddent changes from high to low pressures. I wish those same doctors would explain EXACTLIER... .

the fact that we have blood in the eye arteries which changes it's flow when we abruptly raise our head's inverting the flow, would produce an effect of inflation in them (eye arteries) and thus the eyes white substance would react similarly to a TV screen which is being tuned into a specific freequency... . i dont know, i am not a Doc, but i imagine it happenning that way, due to the felt effect.
