Overview
- Williams, 51, says his eyesight has become progressively blurry since using the weight‑loss injection Mounjaro, affecting his ability to see fans during performances.
- He says he first noticed the problem at an American football game and has since needed a stronger prescription and new glasses.
- Despite the concerns, he says he will likely continue the injections and urges others to research potential risks.
- Mounjaro maker Eli Lilly says patient safety is a priority, that it is reviewing ophthalmic safety data with regulators, and advises patients with side effects to speak to a doctor.
- Recent research has flagged a possible link to rare optic nerve disorders such as NAION, with a UK watchdog reporting just under 300 eye‑problem cases tied to Mounjaro and more than 2.5 million people in Britain using similar drugs.
