Weight-loss medications and vision, what should you know?
Robbie Williams recently shared that he’s been experiencing blurry vision since starting the weight-loss medication Mounjaro (tirzepatide). He described audience members appearing as indistinct shapes, even up close.
He believes the change may be linked to the medication rather than age. Around the same time, a 2024 study published in JAMA (involving over 17,000 patients) reported higher rates of certain serious eye conditions, particularly a rare optic nerve problem, among some people using semaglutide-based medications. This doesn’t mean these medicines are “bad”. They can be very effective and, for many people, life-changing. But it does remind us that any new medication should be monitored, including its effect on vision.
In our practice, we’re hearing more people mention visual changes after starting these injections. Not everyone is affected, but it’s important to pay attention.
If you use Mounjaro, Ozempic, or Wegovy and notice:
- blurry vision
- difficulty focusing
- reduced clarity at any distance
or a sense that your eyes just “aren’t working the same”, please have your eyes checked, and let your prescribing doctor know. Early assessment matters.
These medications can be part of a healthy plan, and your eye health deserves to be part of that conversation.
Have you noticed any changes in your vision after starting a new medication?
