Blurred vision may be one of the possible signs of diabetes, ophthalmologist Ivan Zarubin reported.
The doctor explained that persistent vision problems, including difficulties reading small text, are sometimes associated not only with eye diseases but also with disorders of the central nervous system. He noted that symptoms such as dizziness, blurred images, or problems recognizing letters may, in some cases, indicate damage to areas of the brain responsible for processing visual signals.
Furthermore, the specialist emphasized that decreased visual acuity can accompany hypertension and circulatory disorders in the retina. In diabetes, he added, the blood vessels in the fundus are often damaged, which can lead to the development of diabetic retinopathy over time.
Temporary vision deterioration may also occur during migraine attacks. Before the onset of a headache, some people experience visual phenomena — flashes of light, shimmering, or the loss of specific areas of the image.
