what causes you to see stars
, Grandiose visionary. The stars you may be visualizing may be due to increased pressure on your retina due to straining from coughing. The pressure in the retina's veins elevates as the coughing transmits pressure up from the chest, but generally, this is only from very severe bouts. Similar episodes may occur with straining during bowel movements.
When the vitreous gel inside your eye rubs or pulls on the retina, you may see what looks like flashing lights or lightening streaks. You may have experienced this sensation if you have ever been hit in the eye and see stars.. These flashes of light can appear off and on for several weeks or months.
