A member asked:

I have a bad cold. when i cough in the dark, i see bright, jagged lights. whether my eyes are open or closed. is this normal.

A doctor has provided 1 answer

Cough and cold: When you cough, the force of the cough is transmitted to your head and your eyes. This causes the vitreous gel inside the eye to move, or jiggle back and forth, causing vitreous traction, and hence...Jagged lights. If this occurs when you are not coughing, or if the lights persist, then call your local eye doctor for an appointment. In the meantime, drink lots of chicken soup and rest...
