Type 2 diabetes is often associated with visual changes due to the conditions it can cause over time. High blood glucose levels can lead to various complications, one of which is diabetic retinopathy, where damage occurs to the blood vessels in the retina. This can result in blurred vision, floaters, and potentially significant visual impairment if not managed effectively. It's important for individuals with type 2 diabetes to monitor their vision and undergo regular eye examinations, as early detection can prevent further deterioration of eyesight.

While constant hunger can also be a symptom due to insulin resistance causing the body to become unable to use glucose effectively, visual changes are uniquely indicative of the complications that arise specifically from unmanaged diabetes. Rapid weight loss and excessive sweating can be seen in other conditions or poorly controlled diabetes, but they do not represent the most common symptom associated with type 2 diabetes itself.
