According to the European Medicines Agency, non-arteritic anterior ischemic optic neuropathy (NAION) is a "very rare" side effect of semaglutide medicines, including Ozempic. While this association has been noted, particularly following recent studies, the absolute risk for individuals remains extremely low.

While the overall risk remains low, the European Medicines Agency reported in 2025 that non-arteritic anterior ischemic optic neuropathy (NAION), a condition that can cause blindness, is a "very rare" side effect of semaglutide medicines, including Ozempic. This has prompted crucial questions about how Ozempic and other GLP-1 agonists may impact vision, especially for those with underlying health issues.

A 2024 study in *JAMA Ophthalmology* found that people prescribed semaglutide (the active ingredient in Wegovy) for obesity were seven times more likely to experience certain serious vision changes compared to those on other weight-loss medications. These findings have prompted a closer look at whether **Wegovy affects eyesight** and the potential risks to eye health.

According to official prescribing information, patients with type 2 diabetes taking Zepbound should be aware of a risk of temporary changes in vision. While many experience no eye-related issues, it's crucial for users to understand what are the side effects of Zepbound eyes, ranging from common, temporary visual disturbances to rare but serious conditions.

Clinical studies have documented vision changes in some patients taking Ozempic (semaglutide), with concerns raised about temporary blurred vision, worsened diabetic retinopathy, and a rare, serious condition known as non-arteritic anterior ischemic optic neuropathy (NAION). The question, **does Ozempic cause eye problems**, requires a nuanced look at the potential side effects and existing risk factors.

Recent studies suggest a potential link between semaglutide and Nonarteritic Anterior Ischemic Optic Neuropathy (NAION), but reports on the timing of onset vary significantly. Experts caution that while an association is possible, proving direct causality remains a challenge. The answer to **how long after starting semaglutide does NAION start** is not straightforward.
