1) "The first problem comes because Viagra happens to have a spillover effect. It blocks PDE5, but it also has an effect on PDE6. It turns out that PDE6 is used in the cone cells in the retina, so Viagra can have an effect on color vision. Many people who take Viagra notice a change in the way they perceive green and blue colors, or they see the world with a bluish tinge for several hours. For this reason, pilots can't take Viagra within 12 hours of a flight."

2) "Researchers at the University of Minnesota say that they have diagnosed a condition called non-arthritic ischemic optic neuropathy (NAION) in a group of men who took the erectile dysfunction drug Viagra. NAION is also known as a stroke of the eye. The condition occurs when blood flow to the optic nerve is interrupted, injuring the nerve and causing permanent vision loss.
The researchers studied seven patients regarding Viagra and blurred vision, all men between the ages of 50 and 69. All of the patients took Viagra and blurred vision and vision loss developed within 36 hours of taking Viagra. It has been known for several years that Viagra use can cause temporary color change in patients' vision, but this new condition appears to be permanent."

Its about blood pressure
by anomaly88man on May 3rd, 2009
The chenge in your vision is due to the drop in your blood pressure from Viagra. You may have a blue tinge to objects in your vision from a result of it's use. If your concerned about this ask your doctor.

You're reading Why does Viagra change you color vision? Whenever I take Viagra I know it is kicking in when my vision changes. It is a convenient side effect but a strange one.
