Symptom 5: Blurred Lines – Vision Problems and Eye Discomfort
High blood sugar can also affect your vision, causing blurry or distorted sight. When blood glucose levels are elevated, excess sugar accumulates in the lens of the eye, causing it to swell and alter its shape. This swelling can lead to changes in the eye’s focusing ability, resulting in blurry vision.
In addition to blurry vision, high blood sugar can also cause dry eyes and discomfort, as elevated glucose levels can affect the tear glands’ ability to produce sufficient lubrication. If you experience persistent vision problems or eye discomfort, it’s essential to check your blood sugar levels and consult an eye care specialist to prevent potential complications, such as diabetic retinopathy.
