When you have diabetes, you will experience blurred vision and vision loss. This is because high blood sugar causes the lens of your eye to swell, which changes your ability to see.

1. Diabetes and complications of blurred vision

Diabetes is a complex metabolic disease in which your body either produces insulin, does not produce enough insulin, or simply cannot use it effectively. All of your body's cells need sugar (glucose) to function. Insulin helps break down and deliver sugar to cells throughout your body.
Sugar levels build up in the blood if you don't have enough insulin to break it down, it's hyperglycemia. Hyperglycemia can negatively affect every part of your body, including your eyes. High blood sugar causes the lens of your eye to swell, which changes your vision
Blurred vision is often one of the first warning signs of diabetes. Your vision may be blurred because fluid is leaking into the lens of your eye. This causes the lens to swell and change shape. Those changes make it hard for your eyes to focus, so things start to look blurry.
To correct this type of blurred vision, you need to bring your blood sugar back into the target range. For many people, this can be between 70 mg/dL and 130 mg/dL before a meal and less than 180 mg/dL one to two hours after starting a meal. However, blurred vision can also be a symptom of more serious eye problems. If you feel that your vision is limited or blurred, you should immediately go to medical facilities for a quick examination and treatment by a doctor.
The American Diabetes Association has put together a few eye care guidelines for people with diabetes. Adults with type 1 diabetes should have a complete dilated eye exam within 5 years of diagnosis. Adults with type 2 diabetes should have a complete eye exam soon after diagnosis. See a dilated eye doctor if you are pregnant or planning to become pregnant.
