One of common, yet still rare, side effect that is linked to Viagra (Sildenafil), one of the main erectile dysfunction pills on the market, is a temporary change in vision. These changes include, blurry vision, a difficulty in distinguishing between green and blue color and a sensitivity to light because of a momentary effect to your retina.
Just recently, the Food and Drug Administration added an additional warning to Viagra’s label that blindness, whether temporary or permanent, is associated with Viagra as a very rare side effect. However, severe problems with vision, such as nonarteritic anterior ischemic optic neuropathy (NAION), are not automatically due to Viagra. NAION happens when the flow of blood is stopped before it can reach the optic nerve, causing damage to the nerve, resulting in permanent vision loss.
Doctors have not found a direct relationship as of yet between Viagra use and vision loss. Most clinical tests that have been done on this matter have found that often times, a combination of Viagra and other medical conditions, such as diabetes, heart disease, high cholesterol, and hypertension, create blindness in an individual, such as NAION. A majority of NAION cases brought to light due to Viagra, have occurred in older men in their 50s and 60s who already suffer from vascular or anatomic conditions that create a ripe environment for NAION to develop.
Before you decide to order Viagra online to treat your erectile dysfunction, it is imperative to discuss with a medical professional how susceptible you might be for blindness while taking Viagra. A medical professional will ask to see your medical history to make a good determination if Viagra is right for you. If you do suffer from a medical condition that could warrant blindness, a medical professional might want to monitor you while on Viagra (Sildenafil) and tell you to wait at least 48 hours between dosages to minimize the risk of blindness conditions, including NAION.
