Does Low Blood Sugar Cause Blurry Vision

Risk Factors For Diabetic Retinopathy

Diabetes and Your Eyes – Why do diabetics experience blurry vision?

Anyone with type 1, type 2, or gestational diabetes can develop diabetic retinopathy. The longer you have diabetes, the more likely you are to develop it. These factors can also increase your risk:

  • Blood sugar, blood pressure, and cholesterol levels that are too high.
  • Race/ethnicity: African Americans, Hispanics/Latinos, and American Indians/Alaska Natives are at higher risk.

If you have diabetic retinopathy, low-vision aids such as magnifying glasses and special lenses can help. Ask your eye doctor to refer you to a low-vision specialistexternal icon.

How To Treat Diabetic Eye Diseases

The main treatment for diabetic eye diseases is the tight control of your blood sugar levels. Early on, all that may be needed are frequent eye exams to check the status of your vision. Efforts would also be made to manage your diabetes with medications, diet, and exercise.

You would also need to control your blood pressure and cholesterol, both of which contribute to diabetic eye diseases. Cigarettes should be stopped as tobacco smoke causes blood vessels to further narrow, increasing the risk of diabetic retinopathy and diabetic macular edema.

Additional treatments may be prescribed if you sustain vision loss or are at risk of disease progression. These may involve:

Cataract surgery

Treatments For Diabetic Retinopathy

Treatment for diabetic retinopathy is only necessary if screening detects significant problems that mean your vision is at risk.

If the condition has not reached this stage, the above advice on managing your diabetes is recommended.

The main treatments for more advanced diabetic retinopathy are:

  • laser treatment
  • injections of medication into your eyes
  • an operation to remove blood or scar tissue from your eyes

How Diabetes Can Impact The Eyes

Diabetic retinopathy describes retinal disorders that are caused by diabetes, including proliferative retinopathy and macular edema.

Proliferative retinopathy refers to a condition where blood vessels leak into the corner of the eye. Macular edema happens when leaking fluid causes the macula to swell.

Glaucoma can also cause blurry vision, and diabetes increases the risk for it. Pressure in the eye damages the optic nerve. In the earliest phases, there often are not any noticeable symptoms, which are why regular screening examinations are so important. Here are a few symptoms to watch for between screening examinations:

  • Halos around lights
  • Feelings of nausea or even vomiting

Diabetes also increased the risk for cataracts, and blurry vision is also one of the first symptoms.

As described, there are multiple ways that diabetes can cause blurry vision, but not all blurry vision is the result of diabetes. Other causes include:

  • Low blood pressure
  • Digital eye strain from too much time at a computer
  • Immune system diseases like multiple sclerosis and lupus

If you have an unexplained blurry vision, contact your eye doctor.

This also happens to be just one of many reasons why annual eye examinations are so crucial for many patients. Be sure to follow the recommended frequency of examinations for your age group or according to your doctor or optometrists recommendations.

Causes Of Diabetic Eye Diseases

Diabetes symptoms that affect the eyes

At the heart of all diabetic eye diseases are persistently high blood glucose levels. This can directly or indirectly cause damage to the structures of the eyes.

The damage caused to one part of the eye can have a knock-on effect, leading to additional eye complications and/or accelerating the progression of pre-existing eye diseases.

Do You Suffer From Blurry Vision

Blurred or out of focus vision or any rapid changes to your vision can be an early sign of diabetes. Surprisingly, your diabetes related blurry vision could be caused by any of these factors:

  • Hyperglycemia High blood sugar levels can cause fluid shifts and swelling of your eyes which moves the lens closer to or away from the retina, causing blurred vision.
  • HypoglycemiaLow blood sugar levels cause changes in your brain, preventing your ability to focus.
  • Rising and falling blood sugar levels. Fluctuating blood sugar levels can cause fluctuating vision as your eye changes in size and distance from lens to retina.
  • Your body adjusting to a new insulin or a new dosage of insulin. New insulin levels or new medications may cause shrinking and swelling leading to vision changes.

If the underlying causes are identified and addressed, these vision changes are relatively short term and temporary. However, uncontrolled diabetes or chronic hyperglycemia or hypoglycemia can lead to permanent damage to your vision.

Complications And Risk Factors Associated With Diabetic Eye Diseases

The main concerns about diabetic eye diseases are vision loss and possible blindness. In fact, diabetic retinopathy is the leading cause of vision loss in adults ages 20 to 74 worldwide.

Of the 285 million people living with diabetes around the world today, around one-third have signs of diabetic retinopathy. Of these, a further one-third have vision-threatening eye complications.

In the United States, as many as 40% of people with type 2 diabetes and 80% of those with type 1 diabetes experience some degree of diabetic neuropathy.

Another possible complication of diabetic retinopathy is a detached retina. This can occur spontaneously as scarring or new blood vessel growth displaces the retina from underlying tissues. A detached retina requires immediate medical care to avoid severe vision loss or blindness.

Risk factors for diabetic retinopathy and other diabetic eye diseases include:

  • Having diabetes for a long time
  • Poor blood sugar control

Warning Signs Of Low Blood Sugar

11 Signs You Have Low Blood Sugar

Hypoglycemia can cause both short- and long-term complications. Know the signs so that you can treat the condition as soon as you’re aware of it.

As a person living with diabetes, you know how important it is to reduce blood sugar when it is too high, a phenomenon called hyperglycemia. But blood sugar that is too low, or hypoglycemia, is equally critical to avoid.

“Hypoglycemia happens when the amount of blood glucose drops to a level that’s too low to sustain normal functioning,” says Erin Palinski-Wade, RD, CDCES, who is based in Sparta, New Jersey. “In most people, this is defined as a blood sugar level at or below 70 milligrams per deciliter .”

Hypoglycemia is common among people with type 2 diabetes, according to a review published in June 2015 in the journal PLoS One. Individuals with the condition had an average of 19 mild or moderate episodes of hypoglycemia per year and nearly one severe episode per year on average, according to the researchers. Low blood sugar was particularly common among those taking insulin.

This decrease in blood sugar levels can cause both short-term complications, like confusion and dizziness, as well as more serious issues, including seizures, coma, and, rarely, death, according to the American Diabetes Association .

Hypoglycemia is usually the result of a too-high dose of insulin or a change in diet or exercise habits, according to Harvard Health Publishing.

Precautions For Reducing The Risk Of Diabetic Retinopathy

Reduce the risk of developing diabetic retinopathy, or you can also help stop this condition from getting worse, by maintaining the blood sugar levels, blood pressure and cholesterol levels at optimal levels. In order to avoid Diabetic Retinopathy make the choice of a healthy lifestyle like eating balanced meals, regular exercise, avoiding smoking etc.

Do not miss your regular eye-examinations as many eye complications can be detected early through such screening and vision loss can be prevented. With treatment diabetic retinopathy can be reversed to an extent. But the best thing is to prevent it with early diagnosis.

Diabetes And Blurry Vision: How Diabetes Affects Your Eyes

Reactive Hypoglycemia: Overview and More

Diabetes can affect eye health and vision in many ways. The effects can be short-term or long-term. In many cases, blurred vision is a short-term sign that blood sugar is out of balance, either too low or too high. It can sometimes be the first symptom that a person has before diabetes is diagnosed. This can feel like you just cant quite clear your eyes or like your glasses prescription is slightly off. When blood sugar levels return to normal, so does vision.

High blood sugar and low blood sugar affect vision because they alter how fluids move in and out of the eye. These changes can lead to swelling, and even tiny changes to the eye lens can affect how well the eyes can focus and process light. Low blood sugar may also cause double vision or dimmed vision.

Vision changes can also happen when you start taking a new medication to control diabetes, although the side effect is short-lived.

In some cases, diabetes can cause long-term problems or permanent vision damage, especially if it is not well-controlled. If you have diabetes and notice changes to your vision, let your healthcare provider know right away.

    High Blood Sugar Can Cause Blurry Vision

    How high sugar can damage eyes |Diabetes:Blindness and blurry vision -Dr. Anantharaman Ramakrishnan

    After light enters the front of the eye, known as the cornea, it passes through to the lens. Both the cornea and lens work together to focus the rays of light onto the retina, which is a thin tissue located at the back of the eye. Retina cells then absorb that light and convert it into electrochemical impulses. They are then sent along the optic nerve and to the brain, where they are translated into the image you see.

    Sudden high blood sugar following a meal can lead to blurry vision because the rapid increase in blood glucose causes an integral part of the eye, the lens, to swell. The swelling is caused by fluid moving in and out of the eye, and leads to changes in the shape of the lens and therefore changes in eyesight. When blood sugar levels return to normal, the lens returns to its original shape, and regular vision is restored. However, the effects can last for a couple of days.

    High blood sugar following a meal is known as postprandial hyperglycemia. It has been shown that high carbohydrate intake is associated with the sudden increase in blood sugar levels following a meal.

    Diabetic Eye Disease Prevention

    The best way to prevent diabetes-related eye problems is to manage your blood sugar levels, blood pressure and cholesterol levels.Ways you can help prevent eye problems caused by diabetes include:

    • Control your blood sugar. Your doctor can provide direction on how to keep your blood sugar normal and avoid fluctuations that can lead to diabetic eye diseases. In addition to getting your eyes checked, its also very important to keep the blood sugars under control, says Cai. This is not only good for you overall, but also good for your eyes.
    • Lower your blood pressure and cholesterol. Get recommendations from your doctor on ways you can combat high blood pressure and cholesterol, because these can worsen diabetic eye disease.
    • Stop smoking. Smoking can cause further damage to your blood vessels, including the ones in your eyes, so its very important to stop smoking.
    • Avoid harmful rays. Protect yourself from the suns harmful ultraviolet rays by wearing sunglasses. Exposure to these rays can speed up the progression of cataracts.

    How Does Eating Cause Blurry Vision

    A sudden spike in blood glucose can cause the lens of the eye to swell, as a result of excess movement of fluid entering the lens.

    The lens inside the eye is responsible for fine-tuning and focusing light directly onto the retina for the production of clear, sharp vision. However, excess fluid in the lens can lead to changes in its shape and curvature, affecting the way light is reflected and resulting in blurry vision.

    Once blood sugar levels are controlled, you may notice an improvement in your vision clarity, as the excess fluid drains out of the lens and the lens returns to its usual shape.

    Normal blood sugar levels range between 70-130 mg/dL before meals, and less than 180 mg/dL for up to two hours after meals. Blood sugar levels above this can cause a sudden onset of temporary blurry vision.

    Even if your blurry vision is temporary, it is important to have your eyes examined to rule out serious complications of elevated blood sugar levels.

    What Blood Sugar Levels Cause Blurred Vision

    High blood sugar causes the lens of the eye to swell, which changes your ability to see.

    To correct this kind of blurred vision, you need to get your blood sugar back into the target range.

    For many people this is from70 mg/dL to 130 mg/dL before meals and less than 180 mg/dL one to two hours after the start of a meal..

    Diabetes Diet And Cataract Prevention

    Diabetes symptoms that affect the eyes

    The causes of cataract formation are only partially understood, but free radicals that form in the lens are suspected to contribute. Free radicals have also been implicated in the development of Type 2 diabetes. Free radicals are formed when oxygen reacts with molecules. Once free radicals are produced, they can do damage to your cells and cell membranes. Consuming antioxidants is one way of lowering free radicals and reducing their damage.

    Fruits and vegetables are good sources of antioxidants such as vitamin E, vitamin C, and vitamin A. Although there are no direct studies on plant-based foods and cataracts, fruit and vegetables are known for their high nutrient, high fiber, low-calorie qualities and their value in treating Type 2 diabetes.

    Examples of fruits and vegetables that rank high in antioxidants include:

    • Cranberries, blueberries, and blackberries.
    • Red beans and russet potatoes.
    • Broccoli, cauliflower and artichokes.
