Low Blood Sugar and What to Do! Rule of 15

Sudden, temporary double vision, or short-term double vision, can occur due to a variety of causes, including:

  • Fatigue

  • Trauma or injury

  • Major infection, such as shingles

The intensity of double vision can vary depending on the cause. And, even though short-term diplopia is not typically considered an emergency , it should not be ignored. This is especially true in cases of eye trauma and infection, which should be examined by an eye doctor as soon as possible.

How Does Diabetes Affect My Eyes

Diabetes affects your eyes when your blood glucose, also called blood sugar, is too high.

In the short term, you are not likely to have vision loss from high blood glucose. People sometimes have blurry vision for a few days or weeks when theyre changing their diabetes care plan or medicines. High glucose can change fluid levels or cause swelling in the tissues of your eyes that help you to focus, causing blurred vision. This type of blurry vision is temporary and goes away when your glucose level gets closer to normal.

If your blood glucose stays high over time, it can damage the tiny blood vessels in the back of your eyes. This damage can begin during prediabetes, when blood glucose is higher than normal, but not high enough for you to be diagnosed with diabetes. Damaged blood vessels may leak fluid and cause swelling. New, weak blood vessels may also begin to grow. These blood vessels can bleed into the middle part of the eye, lead to scarring, or cause dangerously high pressure inside your eye.

Most serious diabetic eye diseases begin with blood vessel problems. The four eye diseases that can threaten your sight are

How Do I Know If I Am Hypoglycemic

If your blood sugar levels fall too low, you may experience any of the following symptoms:

  • Irregular or fast heartbeat
  • Pale skin
  • Tingling or numbness of cheek, tongue, or lips

Hypoglycemia can become a medical emergency if your body does not respond to treatment aimed at raising blood sugar levels quickly such as drinking juice or soda, eating a sugary snack or candy, or taking glucose tablets.

If hypoglycemia isnt treated right away, you may experience more severe symptoms that require immediate medical attention, such as:

  • Confusion
  • Blurred vision or other visual disturbances
  • Seizures
  • Loss of consciousness

If you have diabetes, contact an eye doctor near you, who can diagnose and discuss the best treatment options.

Good News Yes Diabetic Retinopathy Can Be Reversed And Yes Diabetic Retinopathy Can Be Reversed With Diet

Overall the number 1 thing is to stick to diet.

Heres a famous one for you: Dr. Walter Kempners rice and fruit diet.

Kempners Rice Diet program began at Duke University in Durham, North Carolina in 1939. The treatment was a simple therapy of white rice, fruit, juice, and sugar, and was reserved for only the most seriously ill patients. Although low-tech, the benefits of the Rice Diet far exceed those of any drug or surgery ever prescribed for chronic conditions, like prediabetes and diabetes.

In addition to diet, DME can be treated with several therapies that may be used alone or in combination, including:

  • Anti-VEGF Injection Therapy

High Blood Sugar Levels: Factors that can Trigger Blurred ...

A range of medical conditions can cause blurry vision, and diabetes is just one.

Most people who start to have blurry vision simply need eyesight correction with the help of an optometrist.

However, anyone who develops blurry visionwhether or not they have diabetesshould see a doctor, especially if:

  • a problem appears suddenly
  • the problem gets worse

Eye problems can stem from new cases of diabetes or a complication of an existing condition.

Anyone who already has a diabetes diagnosis should go for a routine eye examination at least once a year. Regular tests can detect any problems while they are still minor.

Blurred Vision An Important Sign Of Diabetes

By Elisabeth Almekinder RN, BA, CDE

Blurred vision can often be one of the first warning signs of diabetes. Many people who are newly diagnosed end up visiting their primary care providers and education centers having been referred by their ophthalmologist or optometrist due to concerns related to their vision.

Many times, they are unable to obtain a vision prescription until they get their blood sugars down. Once their diabetes is treated and their blood sugars arent elevated, they can be evaluated for the pair of glasses closest to their accurate vision test.

In this article, we will look at why blurred vision is an important warning sign that you may have diabetes in some cases. We will also look at the other causes of blurry vision, some of the treatments for them, and why seeing a vision provider when you have changes in your vision could be the difference between preserving or losing sight in some cases, such as with glaucoma, retinal detachment or macular degeneration.

How Do Doctors Diagnose Eye Problems From Diabetes

Having a full, dilated eye exam is the best way to check for eye problems from diabetes. Your doctor will place drops in your eyes to widen your pupils. This allows the doctor to examine a larger area at the back of each eye, using a special magnifying lens. Your vision will be blurry for a few hours after a dilated exam.

Diabetes Diet And Cataract Prevention

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.
  • Wearing sunglasses to prevent UV ray damage.
  • Regular vision check-ups to detect cataracts in their early stages.

Symptoms of cataracts include blurred vision that cant be corrected with glasses or contact lenses, poor night vision, light sensitivity, seeing stars or halos around sources of light, noticeably fading of colors, and double vision.

What Causes Constant Double Vision

If you suddenly experience constant, ongoing or long-lasting double vision without explanation, it may be the result of a more serious underlying condition and, potentially, a matter of life and death.

A neurological condition can lead to diplopia because of how the brain and vision system work together. If the nerve that sends messages between the brain and eyes is disturbed by a neurological condition, traumatic event or even a brain tumor, it can cause diplopia and other vision problems.

The type of diplopia monocular or binocular can help indicate if a person’s double vision is caused by a problem with the brain or within the eye itself. Monocular diplopia describes when a person experiences double vision even if one eye is closed. Possible causes for monocular diplopia include dry eye syndrome and cataracts.

Binocular diplopia only occurs when both eyes are open and may be greater cause for alarm than monocular diplopia. It’s more likely to be caused by a serious underlying condition, including the following neurological conditions:

Other Causes Of Blurry Vision

High blood pressure can also cause vision problems by damaging the optic nerve or through brain damage resulting from stroke. High blood pressure is very common in diabetes, so its important to keep blood pressure close to normal range as well.

Other eye problems can cause blurriness and blindness. These include age-related macular degeneration . In AMD, the retina gradually stops working for no clear reason, though some studies have found people with diabetes are more likely to have AMD. According to, eating more green vegetables is one way to try to prevent AMD.

Cataracts are strongly associated with diabetes. They are a clouding of the lens in the eye that affects vision. It is thought that proteins in the eye fluid clump up for some reason and cloud the lens. Cataracts are more common in people with diabetes and in smokers. The National Eye Institute says that eating leafy green vegetable and keeping direct sun out of your eyes are good prevention measures.

How Does A Diabetic Eye Exam Work

A diabetic eye exam can occur two ways:

  • An eye doctor places drops into your eyes to dilate the pupils and observe the health of the retina.
  • A special camera is used to take pictures of the back of the eyes.The pictures are sent to a computer program, which uses artificial intelligence to find diabetic retinopathy in the pictures.In less than a minute, the program will determine whether you have diabetic retinopathy and need to follow up with an eye doctor.
  • Getting dilated eye examinations are so important, says Cai. This allows your doctors to identify issues early and offer you treatments if you need them to prevent vision loss from diabetes.

    How Will My Eye Doctor Check For Diabetic Retinopathy

    Hypoglycemia can lead to vision loss

    Eye doctors can check for diabetic retinopathy as part of a dilated eye exam. The exam is simple and painless your doctor will give you some eye drops to dilate your pupil and then check your eyes for diabetic retinopathy and other eye problems.

    If you have diabetes, its very important to get regular eye exams. If you do develop diabetic retinopathy, early treatment can stop the damage and prevent blindness.

    If your eye doctor thinks you may have severe diabetic retinopathy or DME, they may do a test called a fluorescein angiogram. This test lets the doctor see pictures of the blood vessels in your retina.

    Diabetes Treatment And Blurriness

    For people who take medication to increase insulin in the body, changing the timing of food or a change in activity levels can result in low blood sugar levels.

    Blurriness from low blood sugar does not result from changes in the eye. Instead, it is due to the way hypoglycemia affects the brain.

    Vision that changes in this way will return to normal after glucose levels return to normal.

    What Else Can I Do To Protect My Eyes Heart Nerves Feet And Kidneys From Diabetes

    Work with your healthcare team to develop a treatment plan that helps you manage diabetes.

    • Get regular exercise.
    • Lose weight, if you need to.
    • Eat healthy foods and follow your diabetes meal plan.
    • Take all your medicines as instructed by your healthcare provider.
    • Get regular checkups for your eyes.
    • Get regular checkups for your feet. Be sure to wear shoes that fit properly and check your feet every day for injuries, blisters, or redness.
    • If you smoke, ask your healthcare provider about a plan to help you quit.

    What You Should Expect From An Eye Exam

    Your ophthalmologist will first check for any changes to your glasses or contact lens prescription. People with many diabetes related problems with their vision can still wear contact lenses.

    The doctor will then dilate your pupils and examine the retina. The drops used may sting for a short time. About 20 to 30 minutes later, your eyes will be fully dilated. With the use of special lenses and lights, the doctor will visually examine your retina.

    To detect retinopathy, the doctor looks at all the retinal tissues. For signs of macular edema, the doctor looks at the macula in the back of your eye, but this may not be enough for a diagnosis. Your doctor may perform an optical coherence tomography, which is a laser exam of the back of the eye. While the retina is very thin, the test can measure retinal thickening as small as a thousandth of a millimeter.

    A fluorescein angiogram is a test that can detect diabetic retinopathy. During the test, a dye is injected into your arm. Within 45 seconds, the dye reaches the back of the eye. Just like how blood leaks from weak blood vessels, so does the dye. Special photographs help document the results.

    Hypoglycaemia – How to Treat and Prevent Low Blood Sugar

    By Anna Barden

    While double vision, or diplopia, is typically fleeting, it can indicate a serious and possibly life-threatening problem, such as an aneurysm or brain tumor. If you experience sudden, unexpected double vision for several hours, or if you notice any other dramatic changes in your vision, its important to see your eye doctor right away for proper assessment and diplopia treatment.

    Double vision can occur suddenly and last for different periods of time and to varying degrees of severity for each individual person and occurrence.

    Temporary cases of diplopia are less likely to require serious medical attention than ongoing or reoccurring cases. Double vision can occur in both children and adults as a symptom of an underlying condition or due to everyday circumstances, such as fatigue or stress.

    What Does Diabetes Do To The Eyes

    Is diabetes that bad for your eyes?

    Your blood sugar can temporarily affect your vision. Blurred vision is common with people who have diabetes. If your blood sugar is high, water will be pulled into the lens of your eye, swelling it and blurring your vision.

    You shouldnt bother with new glasses or contacts if you havent been on top of your blood sugar levels. It usually takes six weeks or so for blood sugar levels to normalize after youre taking care of it. If you get new glasses or contacts in that time, youll get the wrong prescription.

    Usually you should wait for at least two months after youve gotten your blood sugar levels right to go to the optometrist. But diabetes can cause long-term damage too.

    Diabetic retinopathy is the problem you need to be aware of. If youve had diabetes, over time your eyes will get worse because the blood vessels in your retina will get weaker and thinner. Eventually they can form micro-aneurysms, small bubbles that come out of the side of the weakened blood vessels.

    When those areas get weak they leak exudate, a fatty protein that can solidify into problem areas. Leakage into the center of the eye will cause you to lose vision in that area, which can cause vision changes that are permanent.

    Dry Eyes And Screen Use

    Dry eyes are a common cause of blurriness. One cause of dry eyes is when blinking is reduced over long periods of looking at a screen. Computer workers may notice blurred vision due to dry eyes.

    To prevent dry eyes, try the following:

    • changing the lighting
    • taking breaks away from the screen

    It is important to get an eyesight check from an optometrist, too.

    How Does Diabetes Affect Your Eyes

    Diabetes can lead to blurry vision in several ways.

    In some cases, its a minor problem that you can resolve by stabilizing your blood sugar or taking eye drops. Other times, its a sign of something more serious thats worth discussing with your doctor.

    In fact, blurred sight is often one of the first warning signs of diabetes.

    Other Types Of Diabetic Eye Disease

    Does Diabetes Cause Sleep Problems?

    Diabetic retinopathy is the most common cause of vision loss for people with diabetes. But diabetes can also make you more likely to develop several other eye conditions:

    • Cataracts. Having diabetes makes you 2 to 5 times more likely to develop cataracts. It also makes you more likely to get them at a younger age. Learn more about cataracts.
    • Open-angle glaucoma. Having diabetes nearly doubles your risk of developing a type of glaucoma called open-angle glaucoma. Learn more about glaucoma.

    Reduce Your Risk Of Diabetic Retinopathy

    You can reduce your risk of developing diabetic retinopathy, or help prevent it getting worse, by:

    • controlling your blood sugar, blood pressure and cholesterol levels
    • taking your diabetes medicine as prescribed
    • attending all your screening appointments
    • getting medical advice quickly if you notice any changes to your vision

    Regular Diabetes Eye Checks

    A regular doctor or optician does not carry out the annual eye check for people with diabetes.

    Instead, optometrist or an eye doctorcalled an ophthalmologistperforms this specialist examination.

    An eye doctor can then treat any problems that they find. Only ophthalmologists can treat a disease of the retina.

    The specialist looks at the back of the eyethe retinaafter making the pupil bigger with a drug delivered in eyedrops.

    This is the dilated eye exam, and it detects the signs of diabetic retinopathy, a disease of the retina that results from diabetes.

    If a person already has diabetic eye problems, the person will need multiple follow-up checks every year.

    During pregnancy, a person should have more regular checks.
