James Thompson filed the civil suit against Pfizer in the U.S. District Court for the Southern District of Texas on Tuesday and is seeking more than $75,000 for his vision loss.
He is also seeking class-action status because it has been estimated that 23 million people have taken Viagra, the trade name for the drug Sildenafil, since 1998.
The U.S. Food and Drug Administration said last month it had received more than 40 reports of blindness in men taking impotence drugs, but had not determined if the drugs were responsible.
In the court filing, Thompson says the company failed to warn consumers that taking Viagra could cause non-arteritic anterior ischemic optic neuropathy (NAION), which restricts the flow of oxygenated blood to the optic nerve, causing irreversible vision loss.
