Clinical Trial Shows Cialis Does Not Cause Blindness
A study has been completed which tested Viagra and Cialis against the accusation that blindless may occur, or at the very least vision problems. In a 6 month study a group of men taking viagra and cialis daily did not experience any vision loss, or vision impairment. However there were some vision side effects, several men taking the drugs reported having a bluish tint in their vision, however the quality of sight was not improvised.
Now that Viagra and Cialis have been proven in clinical trials to have no adverse effects on vision, why not give them a try? Anyone over the age of 18 can buy cialis online, and who knows how much the decision to try a new ED drug could help your sex life.
Viagra and related drugs work by blocking a chemical called PDE5, which normally causes the penis blood vessels to contract. The same chemical also acts on cells inside the human eye, which explains the strange coloring of vision. So the age old myth has been solved, and even though viagra does not cause blindness any individual ordering viagra online should read the side effects to ensure its safe.
The details of the study were 244 men, between 30 and 75. 1/3rd took Viagra, 1/3rd took Cialis, and 1/3rd took a placebo.After taking the pill all of the participants took eye exams, checking for adverse affects. Of all the men in the study, the scientists couldent find any difference physically or chemically in the eye that could cause blindness, or blue tinted vision. So while its proven not to cause blindness, its not guaranteed.
Viagra and Cialis are the top selling ED pills in America today, with billions in sales revenue. The online market has transitioned into an online pharmacy type marketplace where anyone who is experiencing erectile dysfunction has the ability to purchase Cialis immediately.
