Diabetes Blurry Vision | Symptom No 6 Of 10 Symptoms of Type 2 Diabetes

Symptoms of Type 2 Diabetes – Vision Becomes Unclear

Symptoms of type 2 diabetes like the diabetes blurry vision symptom may include changes in your eyesight. It is not unusual for people to visit their eye doctor because of vision problems and subsequently be advised to visit their primary physician for screening.  The eyes and the blood vessels that supply nutrients and oxygen are negatively affected by high blood sugar.

At the onset of diabetes, as blood sugar is elevated, the lens of the eyes swell. Unclear vision is a common  complaint that can lead to a type 2 diagnosis. The diabetes blurry vision symptom is one of ten symptoms of type 2 diabetes.

Eye Disease – A Complication of Diabetes

Uncontrolled blood sugar can cause serious complications for your eyes.   The most common diabetic eye disease is diabetic retinopathy. Many times there are no symptoms of this disease in the early stages – not even blurred vision. This is why it is important to have regular eye examinations.  Eye tests will reveal conditions such as retinopathy.

Diabetic Retinopathy

Diabetic retinopathy is a disorder of the retina and there are two types of retinopathy.  Nonproliferative retinopathy is common in symptoms of type 2 diabetes and affects the capillaries at the back of the eye without noticeably affecting vision.  Effective treatment is available and can stop and sometimes reverse vision loss.

If type II symptoms like diabetes blurred vision are ignored, nonproliferative retinopathy can progress to proliferative retinopathy. In this disease, the blood vessels in the eyes become so damaged they close off.

Several factors influence your vulnerability to retinopathy including blood sugar control, blood pressure, how long you have had diabetes as well as genetic history.


A person with type 2 diabetes is 40% more likely to have glaucoma than someone without the disease.  Glaucoma is caused by the buildup of pressure in the eyes, resulting  in gradual vision loss.


Cataracts are very common in aging eyes but are also included in the diabetes blurry vision symptom as one type 2 symptom.  Cataracts cause the lens of the eye to become clouded, interfering with vision.  Wearing sunglasses can help prevent or slow the development of cataracts.

Blood Sugar and Vision Health

Unclear vision and other symptoms that affect the eyes can take as long as 3 months to improve once blood sugar becomes regulated.  Being diabetic is the leading cause of new cases of blindness among people aged 20-74, so it is vital to take changes to your eyesight seriously.

Most people who have symptoms of type 2 diabetes will only have minor eye disorders if they are careful to regulate their  blood sugar and take care of their vision with regular visits to an ophthalmologist.

Other type 2 symptoms can include excessive hunger and weight gain, excessive thirst, lots of bathroom breaks, fatigue, slow healing sores or bruises, dry itchy skin, numbness and tingling in hands or feet, and frequent infections.
