It's true! You can go blind!

Vigorous sex can cause blurred vision, according to Johns Hopkins University researchers. The temporary condition called Valsav retinopathy, usually is associated with other forms of exertion, such as weightlifting or with prolongued vomiting or severe coughing. It results from tiny blood vessels breaking or delicate tissue at the back of the eyeball tearing. Dr, Neil M. Bressler, a coauthor of the study, commented, “Maybe this gives us a physical explanation as to why there were some old wives’ tales that certain sexual activities could result in blindness.”
