About one-third of diabetics are thought to be unaware that they have the condition. Diagnosing diabetes frequently happens as a result of an eye doctor appointment for unexpected vision difficulties or inexplicable blurriness.
Do you have eyesight problems?
Any sudden changes to your vision, including blurry or “out of focus” vision, may be an early indicator of diabetes. Surprisingly, any of the following could be the cause of your diabetes-related hazy vision:
- Hyperglycemia: Excessive blood sugar can induce swelling and fluid shifts in the eyes, which can cause the lens to slide in or out of alignment with the retina, impairing vision.
- Hypoglycemia: Your brain changes as a result of low blood sugar, making it difficult for you to concentrate.
- Increases and decreases in blood sugar levels. Variations in blood sugar levels can lead to variations in vision because of changes in the size and distance between the retina and lens of your eye.
- Your body acclimating to a new insulin or insulin dosage. Changes in vision may result from shrinking and swelling brought on by elevated insulin levels or new drugs.
These vision alterations are transitory and only last a short while if the underlying causes are found and treated. On the other hand, uncontrolled diabetes, as well as chronic (long-term) hyper- or hypoglycemia, can cause irreversible visual impairment.
Diabetes’s Long-Term Effects on Vision
Diabetic retinopathy and perhaps diabetic macular edema are the final results of uncontrolled diabetes (and blood sugar) or persistently elevated blood sugar. One problem that might result in glaucoma is an accumulation of pressure inside the eye.
Retinopathy in Diabetes
The most frequent eye consequence of the condition is diabetic retinopathy. “One in three persons with diabetes who are older than 40 already have some signs of diabetic retinopathy,” states the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
The most frequent cause of vision loss in diabetics is diabetic retinopathy. Regular care has a major impact on each person’s viewpoint. Early detection and treatment of diabetic retinopathy can 95% lower the chance of blindness.
Diabetic retinopathy that is left untreated or badly managed can result in other visual problems such as cataracts and glaucoma, which are usually simple to identify and manage in people without diabetes. Since retinopathy is difficult to diagnose, it’s critical to get yearly eye exams as part of your diabetic treatment.
Diabetic Retinopathy Stages
Background Retinopathy: The initial stage of the illness is known as background retinopathy. The thickening of the base membrane and the reduction of healthy cells surrounding the blood vessels impact the retinal blood vessels as part of the microvascular disease process.
As a result, the blood vessels weaken and become more vulnerable to microaneurysms, or tiny blood vessel dilatation. At the rear of the eye, they take the form of red dots. They will eventually vanish, but in the meantime, they are an indication that the vessels are fragile and could eventually burst or rupture.
Hard exudates and retinal hemorrhages are the results of blood being spilled in this situation. Exudates are essentially the remnants of past bleeding. Vision loss will result if they happen in the macular region of the eye, which is where the lens focuses an image at the rear of the eye.
Proliferative Retinopathy: This is the stage that comes after. The body produces new capillaries to provide blood to the eyes in order to make up for the decreased blood flow to the eyes. The capillaries are proliferating throughout the eye, especially in the vitreous body, which is where the word “proliferative” originates.
The vision will become hazy if these capillaries bleed. They will clot or become fibrotic as they heal. At this point, they have the potential to pull the retina, leading to retinal detachment and blindness.
Treatment – Laser surgery is used to cauterize blood vessels and capillaries that may be of concern in order to treat diabetic retinopathy. Maintaining low and steady blood sugar levels is the other option.
It is crucial to comprehend how food impacts blood sugar levels because managing blood sugar is a never-ending endeavor. A diabetic diet plan that emphasizes eating the correct meals and at the right times should be put into practice. As part of your continued treatment, you should start an exercise regimen.

Complications: You have a twofold increased risk of developing cataracts or glaucoma if you have diabetic retinopathy. When new blood vessels form in the colored area of the eye, called the iris, it can lead to glaucoma. This disruption of fluid flow and increase in internal pressure within the eye can be caused by these new blood vessels.
Treatment for glaucoma is challenging and frequently involves laser surgery to minimize blood vessels on the retinal surface and in the iris. The clouding or fogging of your eye’s lens is known as a cataract. You will frequently only see this in one eye’s lens.
Diabetes Type 2 and Cataracts
Those with type 2 diabetes have a much higher incidence of cataracts than people without the disease, and people with better glucose control have a lower incidence of cataracts than people with higher HbA1c levels.
Opacified lenses are known as cataracts. Light can flow through your lenses because they are composed of water and protein molecules that have been carefully organized. When the protein molecules in cataracts cluster together, they become opaque to light.
According to the American Academy of Ophthalmologists, more than 22 million Americans over 40 have diabetes-related cataracts. Over half of all Americans receive a cataract diagnosis by the time they are 80 years old.
The World Health Organization states that in middle-class and upper-class nations with Western diets and high rates of Type 2 diabetes, cataracts are the primary cause of blindness.
Diabetes Medication and Preventing Cataracts
Although the exact origins of cataract development are unknown, free radicals that accumulate in the lens are thought to play a role. The onset of Type 2 diabetes has also been linked to free radicals. Oxygen interacts with molecules to produce free radicals.
Your cells and cell membranes may sustain harm from free radicals once they are created. One strategy to lessen free radical damage is to consume antioxidants.
Antioxidants including vitamin E, vitamin C, and vitamin A can be found in fruits and vegetables. Fruits and vegetables are recognized for their high nutrient, high fiber, low calorie, and beneficial effects on the treatment of Type 2 diabetes, despite the lack of direct research on the relationship between plant-based diets and cataracts.
Fruits and vegetables that are high in antioxidants include the following:
Blackberry, blueberry, and cranberry.
- Dried fruits and apples.
- russet potatoes and red beans.
- cauliflower, broccoli, and artichokes.
- Hazelnuts, pecans, and walnuts.
There are more ways to avoid or lower your risk of cataracts and vision impairments, such as:
- preserving a healthy weight.
- regulating your blood pressure.
- regulating your HbA1c and blood sugar levels.
- refraining from smoking.
- putting on sunglasses to shield skin from UV rays.
- routine visual examinations to identify cataracts early on.
Cataracts can cause a variety of symptoms, such as double vision, poor night vision, light sensitivity, seeing stars or halos surrounding light sources, and impaired vision that is not correctable with glasses or contact lenses.
Managing Your Type 2 Diabetes While Preserving Your Vision
Be Proactive: Taking better care of your eyes should involve more than just yearly visits to your optometrist, particularly if you already have diabetes or are at high risk of developing it. Like many other physical conditions, diabetes is at least 33% the result of obesity.
According to research from the Harvard School of Public Health, the single biggest predictor of Type 2 Diabetes development was being overweight or obese.
Maintain A Healthy Body Weight: Dietary and exercise regimens that are stringent are recommended by health and fitness experts to both prevent Type 2 diabetes, which is mostly caused by obesity, and to promptly and effectively treat the condition in cases where it has already materialized. You may naturally safeguard your eyes by taking care of your body in a preventative or restorative manner first.
Maintaining stable blood sugar levels at all times is the most crucial step in managing diabetes and safeguarding your vision. Everybody reacts to glucose variations differently, therefore even a slight change in glucose levels might cause visual changes.
If someone informed you that performing a specific action could cause blindness, as a diabetic, you would take great care to ensure that you never did that action again. One of the simplest methods to avoid blindness is to control your blood sugar, however many diabetics disobey this advice.
Manage Your Cholesterol: Blood cholesterol is another important parameter to maintain in check. Blood flow is affected by cholesterol. Blood pressure is impacted by it. It impacts fat accumulation. Heart rate is impacted. And on and on it goes. If cholesterol is allowed to go out of control, it will eventually lead to a huge calamity, much like a runaway train.
Control Your Blood Pressure: One more important preventive action you can do is to keep your blood pressure in check. Nothing is more sensitive than your eyes, therefore whenever you raise blood pressure, those are the first parts of the body to feel the effects.
Quit smoking; it narrows blood vessels and lowers blood flow. Diabetes also lowers blood flow and narrows blood vessels. Smoking is among the riskiest habits a diabetic can have! Tissue damage and necrosis will result from restricted blood flow, which will ultimately lead you to lose circulation to your extremities (fingers and toes).
Smoking and diabetes together can damage your skin, tissues, and blood vessels—especially the blood vessels in your eyes, which can result in blindness and visual loss.
