The Viagra was first launched in 1988, and it is believed that around 23 million men have consumed it although its manufacturer, the Pfizer Company, denies the numbers.

Few of these people know that they may suffer eyesight problems, many of them being irreverable.

At the highest risk are those men who previously suffered from heart problems like heart attacks and even strokes. They are at great risk of having their eyesight damaged as the anterior optic nerve may be receiving a lesser blood flow, giving rise to tissue damage. This condition is called non-arteritic anterior ischaemic optic neuropathy but also the stroke in the eye. Men who do not have a history of heart attacks are not in such danger.
Although most of the doctors try to prescribe Viagra cautiously, many men get them online and risk their health that way.

The Viagra’s manufacturer reports that the eye stroke is common in patients who are aged over 50 years and those who suffer from diabetes, high cholesterol and high blood pressure.
