If you are diabetic, know that high blood pressure level can take a severe toll on your eyes in the form of blurry vision, cataract, glaucoma and retinopathy, if left unchecked. It can even lead to partial/complete blindness in young adults. Nonetheless, a strict control over your blood sugar count would prove effective in preventing such eye complications in the long run.
How does diabetes affect the eyes?
Blurry Vision: Diabetes can cause swelling of the eye and damage to your vision. In case you are already using glasses, it might bring about fluctuations in your optical power. Once your blood sugar count gets back to the normal level; that is within the range of 70 to 130 milligrams per deciliter, your vision would be normal again; though this might take some time (about 3 months).
Cataract: Eye lens works just like a camera, helping you to focus on a particular object. Cataract is a condition wherein this lens gets clouded with debris. Nevertheless, diabetic patients are more vulnerable to cataracts as compared to others. It has to be removed with a surgery wherein an artificial lens replaces the blurry eye lens.
Glaucoma: Pressure starts building up within the eyes when fluids do not get drained out normally. This damages the nerves and blood vessels, thereby causing vision loss, blurred vision, watery eyes and headaches. Generally, glaucoma can be cured with laser, surgery, eye drops or medicines. Medications do help in alleviating eye pressure, reducing excessive fluid production and facilitating drainage. Having said that, diabetics are likely to develop neovascular glaucoma, a rare complication wherein new blood vessels form on the iris (the ring-shaped colored region in the eye), obstructing the normal fluid flow and further increasing the eye pressure.
Diabetic Retinopathy: The retina is a cluster of cells behind the eyes that absorb light and converts them into images which are then transmitted to the brain through the optic nerve. High blood sugar levels damage the tiny blood vessels of the retina, leading to a condition called Diabetic retinopathy.
The stages of diabetic retinopathy
The retina requires a constant blood supply via a network of small blood vessels. In due course of time, a high blood sugar count might damage those blood vessels; primarily across three stages:
Background Retinopathy: This is a condition wherein tiny lumps develop in your blood vessels, causing slight bleeding that usually does not affect your eye sight.
Pre-proliferative Retinopathy: This is a condition characterized by significant bleeding from the eyes as a result of the blood vessels being severely affected.
Proliferative Retinopathy: Proliferative retinopathy is a condition wherein new blood vessels and scar tissues that bleed easily develop on the retina, leading to vision loss.
Are you at risk?
The risks of Diabetic retinopathy increase if one is suffering from diabetes. Apart from this, certain other factors could also aggravate the chances of this disorder:
Rise or fall in blood sugar
Rise in the blood pressure level
Excessive consumption of tobacco
When should you call a doctor?
When you experience spots in your vision
In case of blurred and fluctuating vision
Impaired color vision
Sudden loss of vision
Redness and pain in the eyes
These signs serve as an early wake up call. However, it’s not mandatory for these signs to indicate towards diabetic retinopathy.
How to protect your eyes from diabetes and keep them healthy?
Get your eyes checked periodically and try and maintain a steady blood sugar count.
Take the prescribed medicines on time.
Try to achieve and then maintain optimal weight levels.
Avoid a sedentary lifestyle and engage in some sort of physical activity.
Control your cholesterol levels by picking the right kind of foods.
Abstain from smoking and limit alcohol consumption.
Opt for a healthy diet comprising of green and leafy vegetables, oily fish, tuna, salmon; protein rich foods such as beans, nuts and eggs; citrus fruits such as oranges; pork and oysters.

I am facing a problem in my eye. My right eye sight is less clear than my left eye sight. If I read newspaper with my right eye closed, the left eye sight is good and clear, but if I close my left eye and read the same thing, the eye sight is less clear from a foot distance but if I read it from very near I can see the same thing from the less clear eye sight. Please help.

Ebooks maybe are a lot easier to carry, and with the emerging trend of Kindles, it may appear to be more convenient than paperbacks, but the smell of new books, the texture of its pristine pages, is unparalleled to the inanimateness of ebooks. But that is not just why you must choose paperbacks over ebooks. Read on to find out why paperbacks work well over ebooks for better eye health.
- Does not involve light-emission- The backlit electronic devices, strain your eyes, causing redness, irritation and watering. Most doctors advise that exposure to light during the evening, especially from artificial sources should be minimal. On the other hand, books do not emit any harmful rays, making it the obvious choice if you want to take good care of your eyes.
- Do not hamper body clock: Our system has a tendency to adapt itself to the rhythm of life by responding to the surrounding light. However, the blue light in reading devices disrupt the release of melatonin or the sleep hormone, causing inadequate, less deep sleep, and fatigue and irritation the following morning. Thus, not giving enough time to your eyes and body for revitalizing. On the other hand, studies have shown that people reading books sleep better and timelier than those reading on devices.
- Proximity to device not required- The admonition of not sitting too close to the television's screen glare is nullified by reading devices where a certain level of proximity is required for comfortable reading, which harms our eyes. But paperbacks do not have any such risk involved as there is no glare that would affect our eyes.
- Does not induce disrupted winking- Electronic devices often trigger a tendency to not blink and stare at the screen constantly for longer than advisable. That does not give the lenses in your eyes the momentary rest that the eyes require in order to replenish themselves.
Exercises to improve eye health
There are many common measures people take to improve their eyesight or improve their vision. These include wearing glasses, lenses, sunglasses and many such measures. Here are some effective exercises which prove to be highly beneficial in increasing your eye health:
- Stretching: This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds, then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.
- Flexing: This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.
- Focus switching: This particular eye exercise is used for accommodation and is probably the most useful one. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes which are twenty feet away and this may improve your eyesight.
- Palming: This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to destress the eyes.
- Deep blinking: This is also an incredibly useful exercise for distance vision. All you have to do is to place some large letters at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After the gap of 5 seconds, open your eyes and see the letters for a second or two. The more time you do this the more clearly you will be able to see the letters after reopening your eyes.
Finally, a warning has to be given that these eye treatments are not universally accepted by all doctors.

While spectacles are a fashion statement for some people, for others they are an uncomfortable necessity. Though contact lenses may be a little more aesthetically pleasing they too can be quite uncomfortable and cannot be worn throughout the day. Thankfully, there is a third way to correct vision. Laser sugery or LASIK, it is a popular refractive procedure that can correct common vision problems, such as nearsightedness, farsightedness and astigmatism. This procedure aims at reshaping the cornea so that light entering the eyes can be focused onto the retina for the person to have a clearer vision.
- Laser surgery is pain-free and quick in most cases. Usually, it does not take more than 15 minutes to correct vision in both eyes. The results of this surgery can be seen in as little as 24 hours.
- The first step of laser surgery to correct vision is to create a thin, circular flap in the cornea. This is then folded back to access the stroma or underlying cornea. An excimer laser is then used to remove some of the corneal tissue.
- For people suffering from nearsightedness, the cornea is flattened while for people suffering from farsightedness, the cornea is made steeper. In cases of astigmatism, an irregular cornea is smoothened.
- Once the correct gradient has been achieved the corneal flap is put back into place and the cornea is allowed to heal naturally. There are no stitches or bandages required in a laser eye surgery.
- You may feel a temporary burning or itching sensation in your eyes immediately after the procedure. It is important not to rub your eyes or place any pressure on them. Your vision may also be cloudy or blurred for the first few hours.
- A doctor will usually advise you to rest for a few days after the surgery so that your cornea can heal properly. In a few days, your eyesight should stabilize, though, in a few rare cases, it may take a little longer. You should also avoid any form of strenuous exercising for a few days after the surgery.
Though LASIK surgery has a very high success rate, there are very rare occasions where spectacles may still be needed even after the surgery. Thus LASIK is a choice of treatment for many who seek freedom from glasses. In case you have a concern or query you can always consult an expert & get answers to your questions!
