Cenforce 100mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is a PDE5 inhibitor. This drug increases blood flow to the penis during sexual stimulation, helping to achieve and maintain an erection. It works by relaxing the blood vessels, but it can also affect other parts of the body—including the eyes. While most visual issues with Cenforce 100mg are mild and temporary, you should take them seriously. If you experience vision changes—especially sudden or severe ones—stop using the medication and seek medical help immediately. Always use Cenforce 100mg under medical supervision to reduce your risk of complications, and avoid taking more than the recommended dose.
