Viagra is a godsend for millions of men who suffer from impotence, but studies have found the drug can cause numerous side effects. The results of a recently released study found that one of its ingredients can cause blindness.
Sildenafil, the active ingredient in Viagra, obstructs an enzyme that sends light signals from the retina to the brain. Doctors have known for several years that it could cause temporary vision problems in healthy men, but a new Australian study found its effects can be permanent.
"The study shows that sildenafil may cause permanent damage," study leader Dr. Lisa Nivison-Smith told Newsmax Health.
People with retinitis pigmentosa — an inherited condition which causes cells in the retina to die — are at greatest risk. Victims lose their peripheral vision, as well as their ability to see well in dim light, and they can become blind. Dr. Nivison-Smith and fellow researchers at the University of New South Wales also found that people whose sight is normal, but carry the gene for retinitis pigmentosa, are at risk as well. They warn that Viagra could cause permanent damage to the retina.

How about I get my flu shot and take Viagra at the same time?
by the looks of some wives, this would be a God send
I guess I will only use it til I need glasses
My wife asked me to go out and get some of those pills that make you get an erection quicker so I went out and got her some diet pills.
If you need it, you fail at life. We need to thin the weak, not aid them with pharmaceuticals.
Funny, they used to say if you self stimulated you would go blind???
