4. Blurred Vision
Blurred vision is one of the common signs of diabetes. You can also experience permanent damage to the eyes and even blindness, but that’s something else entirely. Garden variety blurred vision usually goes away when you get your blood sugar in your target range. High blood sugar causes the lens of your eye to swell up, and that hurts your ability to see. Extremely low blood sugar can also impair your vision, and it can even cause you to have double vision.
Permanent eye damage, or diabetic retinopathy, is one of the major complications of diabetes, so it can be kind of scary when you experience it. Don’t think the worst, though. Blurred vision from high blood sugar is usually temporary and reversible. Once you get your blood sugar in your target range, you’ll be seeing clearly from there on out. Just keep it there in that target range with the right medication and doctor on your side.
