Summary
GLP-1 drugs such as Ozempic and Wegovy have been linked to serious vision concerns, including diabetic retinopathy and optic nerve damage that can result in lasting vision loss Research suggests the highest risk of sudden vision loss may occur within the first year of starting these drugs, with symptoms sometimes appearing overnight without pain or warning Case reports document that even healthy adults using GLP-1 drugs for weight loss — with no history of diabetes or eye disease — have experienced lasting vision loss Sudden changes in vision such as blurriness, blind spots, or loss of color perception may be early warning signs of optic nerve damage. Recognizing them quickly can support timely evaluation and care Lifestyle approaches such as reducing vegetable oils, choosing the right carbs, and supporting gut microbes may help support healthy metabolism
