Eye Know, I Care: Tips to take care of your eyes
Eyes are the most essential part of a human body and so is their health. They constantly function from the moment we wake up to the time we shut them to go off to sleep. Our eyes absorb tons of information about the world around us – shapes, colors, movements, and a lot more which is then sent to the brain, allowing one to recognize and function.
One would find numerous health tips around us in order to protect our eyes from any damage or disease. These health tips are usually a broad statement and may not be applicable to all the population, especially if one is already undergoing any health issue. One should note that blindly followed tips can make you go blind.
To give you a clear insight and understanding, Dr. Susheel Deshmukh, Glaucoma and Cataract consultant, Bhojraj Chanrai Sankara Eye hospital presents a few FACTS and MYTHS that are generally followed, to help reduce the chances of any risk related to eyes and thereby, enhancing healthy eyesight.
Steroids can cause cataract: Steroids, especially if used for a longer period, are known to cause a posterior sub-capsular type of cataract. They impede the normal lens metabolism, leading to cataract.
Looking directly at the sun will damage your eyes Any direct eye contact with the sun destroys photo receptors of the retina, leading to irreversible vision loss, called solar retinopathy. Besides, UV rays also leads to disorders such as mascular degeneration and corneal dystrophies.
Weight lifting/ heavy exercises too can be dangerous for health: Weight lifting/ heavy exercises can cause venous pooling of blood. These exercises do have a risk of having other problems as well like Hernias & Varicose veins.
Crash diet is not a healthy weight loss option: Crash dieting or Dr Atkins diet (zero carb diet) can derange your body metabolism, causing metabolic keto-acidosis and can have multi-systemic implications. In eyes, keto-acidosis can cause retinopathy and adversely affect the vision. Hence, this too needs to be practiced cautiously and with a proper medical consultation and monitoring.
Yoga is good for health: Though largely believed to be good for general health, few Yoga-asanas like shirsannas , or any other asanas where the head posture is below your body level can cause increased pooling of blood in your head and inturn increase the Intraocular pressure (eye pressure) significantly to a pathological levels. Similarly it can be dangerous in a morbid cardiac condition too.
Drinking extensive amount of water leads to a healthy lifestyle: Huge amount of water intake is widely advocated and practiced, as it is believed to flush the toxins out of the body. However, human body doesn’t behave like a clogged drain. This large amount of water ingested over a short time interval gets in turn absorbed into the blood circulation and thus increasing the work load on the Heart function and kidney filtration process.
This can be of serious consequences in cardiac & Kidney patients. Also this can increase the intraocular pressure even in healthy individuals, and can possibly push one to Glaucoma (loss of vision). Hence consuming large amount of fluid as a part of water therapy should be avoided or at least considered after discussion with your doctor.
Artificial sweeteners is a good alternative to sugar: Sweeteners like Aspartame when they are exposed to high temperature, they break down to form free radicals which can severely harm your retina and optic nerves. Aspartame and its degradation products have also been linked to blurred vision, eye pain, visual hallucinations and blindness. One should only occasionally use it when you need to sweeten a cup of tea or prepare some baked goods that could use a little extra sugar.
Substituting aspartame for the sugar can actually be beneficial for you. However, if you are using aspartame routinely, there’s a good chance you’re putting yourself at risk to suffer from some of the side effects above. Do not exceed 50mg/1kg (FDA Safety limit) body weight when using aspartame. There is a good chance you should use significantly less than that to avoid negative side effects altogether.
Staring at a computer screen is bad for eye health: Spending an entire day looking into a computer screen can tire or strain your eyes, but it will not hurt them. The redness, irritation, dryness, burning, blurred vision and headaches that one experiences after sustained screen staring are symptoms of computer vision syndrome. This occurs due to a drop in your blinking rate, causing eyes to dry. AC and improperly lit rooms further aggravate the condition.
