It works by increasing blood flow to the penis, which helps in achieving and maintaining an erection. While Viagra is generally safe and effective, there have been rare cases where it has been associated with vision loss.The exact mechanism by which Viagra can cause vision loss is not fully understood. However, researchers have theorized a few possible explanations. One theory is that Viagra may affect the blood vessels in the retina, the part of the eye responsible for vision. It is believed that the drug may cause the blood vessels to constrict, leading to a decrease in blood flow to the retinal cells. This reduced blood flow can potentially lead to damage and vision loss.Another theory suggests that Viagra may interfere with an enzyme called phosphodiesterase type 6 (PDE6), which is found in the retina. PDE6 plays a crucial role in the visual signaling pathway and is responsible for the conversion of light into electrical signals that the brain can interpret as vision. By inhibiting PDE6, Viagra may disrupt this process and lead to vision problems.It is important to note that the occurrence of vision loss with Viagra is extremely rare and has been reported in only a small number of cases. According to a study published in the journal JAMA Ophthalmology, out of the millions of men who have taken Viagra, only a few dozen cases of vision loss have been reported. Nevertheless, it is a potential side effect that should not be ignored.If you experience any sudden or severe changes in vision while taking Viagra, it is crucial to seek
