4 Eye Signs That May Indicate Diabetes (with Detailed Explanation):

1. Sudden Blurred Vision or Decreased Visual Acuity
   When blood sugar levels are high, the pressure inside the eye can fluctuate, affecting the lens and cornea. This causes vision to become blurry or rapidly decline, even without any other obvious cause.

2. Retinal Hemorrhage (Bleeding Inside the Eye)
   Diabetes can damage the small blood vessels in the retina, causing them to rupture and bleed inside the eye. This bleeding leads to dark spots or red streaks in your vision, seriously impairing sight.

3. Retinal Swelling or Macular Edema
   Fluid leaking from damaged blood vessels accumulates in the macula (the central part of the retina responsible for sharp vision), causing swelling and blurred vision. This is a common cause of vision loss in people with diabetes.

4. Appearance of Halos or Blind Spots in Vision
   Due to blood vessel damage and impaired blood flow in the eye, you may see unusual halos or experience blind spots (areas where vision is lost), signaling retinal damage.
