can rubbing your eye cause retinal detachment
Wear your corrective lenses to see where you are going or it won't be just eyes hurt. Floaters, the little bits of scar tissue in the jelly of the eye that lead or lag behind the motion of the eye thus drift or float are made worse in excessive eye rubbing or worse can lead to retinal tears or detachment. Avoid this practice. Treat the itching if that is what the problem is in the first place.
