That could be turned into a prolong giggle, if you submitted to the right person. And
it would sound so much more feminine.

Federal health officials are examining rare reports of blindness among some men using the impotence drug Viagra. FDA clinical trials show that taking Viagra, especially at high doses, can cause some retinal dysfunction and affect sight for a number of hours. Studies show visual disturbances described as a bluish color tinge to the visual field and light sensitivity.The Food and Drug Administration still is investigating, but has no evidence to determined the long-term effects of Viagra yet that the drug is to blame, said spokeswoman Susan Cruzan.

Viagra has also been in the news because of its possible link with sudden failure of the blood supply to the optic nerve. That effect eyes & causes blindness called NAION, or non-arteritic anterior ischemic optic neuropathy. It can occur in men who are diabetic or have heart disease, the same conditions that can cause impotence and thus lead to Viagra use. The FDA has 50 reports of the blindness. Viagra has been taken by more than 23 million men worldwide.
What is NAION?NAION is one of the most common causes of sudden vision loss in older Americans. The condition leads to swelling around the optic disc, a connection point where the optic nerves reach the back of the eye. Ultimately, this swelling compresses the optic nerves and causes a rapid drop in vision. About 6,000 people develop NAION each year, according to the National Eye Institute.
How does NAION develop?The symptoms are painless and often appear without notice. In a study led by researchers at the University of Iowa, about three quarters of NAION patients first discovered their vision was blurry and impaired after waking up in the morning. The condition starts in one eye and can cause complete blindness if both eyes are eventually affected.
