How To Relieve Computer Vision Syndrome And Keep Eyes Healthy

How To Relieve Computer Vision Syndrome And Keep Eyes Healthy

If you’re like many people, a lot of the job that you do during the week is computer-based. As a matter of fact, the American Optometric Association (AOA) estimated that the average American spends 7 hours a day on the computer (or tablet, e-reader or similar electronic device). While for many workers, this is an unavoidable part of the job, it can still lead to a problem called Computer Vision Syndrome (CVS), also known as Digital Eye Syndrome. This condition of eye irritation appears to get worse with increased computer use – but is reversible. Read on to find out more about how to recognize and treat it.

    How CVS is Diagnosed and Recognized

    The first step to understanding CVS is knowing how to recognize the signs and symptoms of this condition. The AOA’s article on the topic goes on to outline the most frequent things to look for, including eyes that are dry or uncomfortable (in absence of problems like allergies) or feel strained as well as headache, blurred vision and pain or discomfort in the neck or shoulders. Also be aware that this can make other vision problems, such as astigmatism or far-sightedness worse.

    If you believe you might be suffering from CVS, make an appointment with your eye doctor. They can give you a diagnosis based on your personal and medical history (including the kind of work you do and how long, on average, you spend on a computer or device on a daily basis), signs and symptoms you are experiencing, and tests to measure visual acuity and other visual skills.

    In the meantime, if you suspect that CVS might be a problem, the AOA recommends that you follow the “20-20-20” rule. This means that, if you are spending all day on the computer, then every 20 minutes or so, take 20 seconds out to gaze at something that is 20 feet away in order to give your eyes a rest.

      Rules to Follow for Fixing CVS

      Apart from the “20-20-20” rule, there are other guidelines to follow that can help you protect your eyes from CVS:

      Rule #1. Avoid glare on your computer screen and experiment with lighting to make sure that you are not getting excessive light in the room, especially not from overhead fluorescent light which is particularly hard on the eyes. Experiment with curtains and shades to keep out excessive natural light as well.

      Rule #2. Be sure that your posture while working on the computer is supported by a good-quality chair and make sure that your computer is around 15-20 degrees below eye level and that your computer screen is around 20-28 inches away from your face. Positioning is everything!

      Rule #3. If it is within your power, choose your computer wisely. The newer liquid crystal screens are supposed to be kinder to the eyes than their old counterparts and a dot pitch of .28mm and a screen size of at least 19 inches are considered ideal.

      Rule #4. Keep in mind that people who wear contacts or glasses are more prone to this eye strain. If you are a wearer, be even more aware of signs and symptoms to watch for.

      Rule #5. Blink often. Although you blink many times a minute just reflexively (without thinking about it), there are plenty of reasons why you should try to blink more often than this, the main one being keeping the eyes cleansed of particles and other being to keep the eyes moist.

      Advertising

      Rule #6. Adjust computer settings so that the size and color of the background and font are as conducive as possible to give your eyes as much of a break as possible.

        What to Do for General Eye Health

        If you do work in an office and are on the computer, there are a few things you can do that will help promote the general health of your eyes. One of the most important things is to protect your eyes from damaging UV rays of the sun with sunglasses and/or a hat with a brim when you are going outside, especially in the middle of the day when the UV rays are strongest. Make sure you go to an optometrist once a year for a routine eye exam and report any changes you have noticed: this can help your eye doctor catch and diagnose a problem early.

        Diet is also important to eye health: include things like carrots and sweet potatoes in your meals that are rich in beta-carotene, an antioxidant which supports visual healthy. Lutein is another antioxidant that is vital for this.

        In short, if you are like many office workers and spend long hours on the computer, you should definitely be aware of the issue of CVS – not only recognizing its signs and symptoms, but knowing what to do to treat or even prevent it.

        Why You’re Feeling Tired All the Time (And What to Do About It)

        Why You’re Feeling Tired All the Time (And What to Do About It)

        Feeling tired all the time?

        Have you ever caught yourself nodding off when you’re watching TV, listening to someone drone on during a meeting or even driving a car?

        I know I have, especially when I worked 70 hours per week as a High-Tech Executive.

        Feeling tired all the time may be more widespread than you think. In fact, two-fifths of Americans are tired most of the week.[1]

        If you’re tired of feeling tired, then I’ve got some great news for you. New research is helping us gain critical insights into the underlying causes of feeling tired all the time.

        In this article, we’ll discuss the latest reasons why you’re feeling tired all the time and practical steps you can take to finally get to the bottom of your fatigue and feel rested.

        What Happens When You’re Too Tired

        If you sleep just two hours less than the normal eight hours, you could be as impaired as someone who has consumed up to three beers.[2] And you’ve probably experienced the impact yourself.

        Here are some common examples of what happens when you’re feeling tired:[3]

        • You may have trouble focusing because memory and learning functions may be impaired within your brain.
        • You may experience mood swings and an inability to differentiate between what’s important and what’s not because your brain’s neurotransmitters are misfiring.
        • You may get dark circles under your eyes and/or your skin make look dull and lackluster in the short term and over time your skin may get wrinkles and show signs of aging because your body didn’t have time to remove toxins during sleep.
        • You may find it more difficult to exercise or to perform any type of athletic activity.
        • Your immune system may weaken causing you to pick up infections more easily.
        • You may overeat because not getting enough sleep activates the body’s endocannabinoids even when you’re not hungry.
        • Your metabolism slows down so what you eat is more likely to be stored as belly fat.

        Are you saying that feeling tired can make me overweight?

        Unfortunately, yes!

        Feeling tired all the time can cause you to put on the pounds especially around your waist. But it is a classic chicken and egg situation, too.

        Heavier people are more likely to feel fatigued during the day than lighter ones. And that’s even true for overweight people who don’t have sleep apnea (source: National Institutes of Health).

        Speaking of sleep apnea, you may be wondering if that or something else is causing you to feel tired all the time.

        Why Are you Feeling Tired All the Time?

        Leading experts are starting to recognize that there are three primary reasons people feel tired on a regular basis: sleep deprivation, fatigue and Chronic Fatigue Syndrome (CFS).

        Here’s a quick overview of each root cause of feeling tired all of the time:

        1. Tiredness occurs from sleep deprivation when you don’t get high-quality sleep consistently. It typically can be solved by changing your routine and getting enough deep restorative sleep.
        2. Fatigue occurs from prolonged sleeplessness which could be triggered by numerous issues such as mental health issues, long-term illness, fibromyalgia, obesity, sleep apnea or stress. It typically can be improved by changing your lifestyle and using sleep aids or treatments, if recommended by your physician.
        3. Chronic Fatigue Syndrome (CFS) is a medical condition also known as Myalgic Encephalomyelitis that occurs from persistent exhaustion that doesn’t go away with sleep.

        The exact cause of CFS is not known, but it may be due to problems with the immune system, a bacterial infection, a hormone imbalance or emotional trauma.

        It typically involves working with a doctor to rule out other illnesses before diagnosing and treating CFS.[4]

        Always consult a physician to get a personal diagnosis about why you are feeling tired, especially if it is a severe condition.

        Feeling Tired vs Being Fatigued

        If lack of quality sleep doesn’t seem to be the root cause for you, then it’s time to explore fatigue as the reason you are frequently feeling tired.

        Advertising

        Until recently, tiredness and fatigue were thought to be interchangeable. Leading experts now realize that tiredness and fatigue are different.

        Tiredness is primarily about lack of sleep.

        But fatigue is a perceived feeling of being tired that is much more likely to occur in people who have depression, anxiety or emotional stress and/or are overweight and physically inactive (source: Science Direct).

        Symptoms of fatigue include:

        • Difficulty concentrating
        • Low stamina
        • Difficulty sleeping
        • Anxiety
        • Low motivation

        These symptoms may sound similar to those of tiredness but they usually last longer and are more intense.

        Unfortunately, there is no definitive reason why fatigue occurs because it can be a symptom of an emotional or physical illness. But there are still a number of steps you can take to reduce difficult symptoms by making a few simple lifestyle changes.

        How Much Sleep Is Enough?

        The number one reason you may feel tired is because of sleep deprivation which means you are not getting enough high-quality sleep.

        Most adults need 7 to 9 hours of high-quality, uninterrupted sleep per night. If you’re sleep deprived, the amount of sleep you need increases.

        So, quantity and quality do matter when it comes to sleep.

        The key to quality sleep is being able to get long, uninterrupted sleep cycles throughout the night. It typically takes 90 minutes for you to reach a state of deep REM sleep where your body’s healing crew goes to work.

        Ideally, you want to get at least 3 to 4 deep REM sleep cycles in per night. That’s why it’s so important to stay asleep for 7 or more hours.

        Research also shows that people who think they can get by on less sleep don’t perform as well as people who get at least seven hours of sleep a night[5] So, you should definitely plan on getting seven hours of deep restorative sleep every night.

        If you are not getting 7 hours of high-quality sleep regularly, then sleep deprivation is most likely reason you feel tired all the time.

        And that is good news because sleep deprivation is much simpler and easier to address than the other root causes.

        It’s also a good idea to rule out sleep deprivation as the reason why you are tired before moving on to the other possibilities such as fatigue or Chronic Fatigue Syndrome, which may require a doctor for diagnosis and treatment.

        4 Simple Changes to Reduce Fatigue

        Personally, I’m a big believer in upgrading your lifestyle to uplift your life. I overcame chronic stress and exhaustion by making these four changes to my lifestyle:

        1. Eating healthy, home-cooked meals versus microwaving processed foods or eating out
        2. Exercising regularly
        3. Using stressbusters
        4. Creating a bedtime routine to sleep better

        So, I know it is possible to change your lifestyle even when you’re working crazy hours and have lots of family responsibilities.

        After I made the 4 simple changes in my lifestyle, I no longer felt exhausted all of the time.

        In addition, I lost two inches off my waist and looked and felt better than ever.

        Advertising

        I was so excited that I wanted to help others replace stress and exhaustion with rest and well-being, too. That’s why I became a Certified Holistic Wellness Coach through the Dr. Sears Wellness Institute.

        Interestingly enough, I discovered that Dr. Sears recommends a somewhat similar L.E.A.N. lifestyle:

        • L is for Lifestyle and means living healthy including getting enough sleep.
        • E is for Exercise and means getting at least 20 minutes of exercise a day ideally for six days a week.
        • A is for Attitude and means thinking positive and reducing stress whenever possible.
        • N is for Nutrition and means emphasizing a right-fat diet, not a low-fat diet.

        The L.E.A.N. lifestyle is a scientifically-proven way to reduce fatigue, get to the optimal weight and to achieve overall wellness.[6]

        And yes, there does seem to be an important correlation between being lean and feeling rested.

        But overall based on my personal experience and Dr. Sear’s scientific proof, the key to not feeling tired all of the time does seem to be 4 simple changes to your lifestyle.

        L — Living Healthy

        Getting enough high-quality sleep every day is the surefire way to help you feel less fatigued, more rested and better overall.

        So, whether you’re sleep deprived or potentially suffering from fatigue or Chronic Fatigue Syndrome, you probably want to find a way to sleep better.

        In fact, if you aren’t getting enough sleep, your body isn’t getting the time it needs to repair itself; meaning that if you are suffering from an illness, it’s far more likely to linger.

        As unlikely as it sounds, though, fatigue can sometimes make it difficult to sleep. That’s why I’d recommend taking a look at your bedtime routine before you go to bed and optimize it based on sleep best practices.

        Here are 3 quick and easy tips for creating a pro-sleep bedtime routine:

        1. Unplug

        Many of us try to unwind by watching TV or doing something on an iPhone or tablet. But tech can affect your melatonin production due to the blue light that they emit, fooling your body into thinking it’s still daytime.

        So turn off all tech one hour before bed and create a tech-free zone in your bedroom.

        2. Unwind

        Do something to relax.

        Use the time before bed to do something you find relaxing such as reading a book, listening to soothing music, meditating or taking an Epsom salt bath.

        3. Get Comfortable

        Ensure your bed is comfortable and your room is set up for sleep.

        Make sure you room is cool. 60-68 degrees is the ideal temperature for most people to sleep.

        Also, it’s ideal if your bedroom is dark and there is no noise.

        Finally, make sure everything is handled (e.g., laying out tomorrow’s clothes) before you get into your nice, comfy bed.

        If your mind is still active, write a to-do list to help you fall asleep faster.[7]

        Above all, be gentle with yourself and count your blessings, some sheep or whatever helps.

        E — Exercise

        Many people know that exercise is good for them, but just can’t figure out how to fit it into their busy schedules.

        That’s what happened in my case.

        But when my chronic stress and exhaustion turned into systemic inflammation (which can lead to major diseases like Alzheimer’s), I realized it was time to change my lifestyle.

        As part of my lifestyle upgrade, I knew I needed to move more.

        My friends who exercise all gave me the same advice: find an exercise you like to do and find a specific time in your schedule when you can consistently do it.

        That made sense to me.

        So, I decided to swim.

        I used to love to swim when I was young, but I hadn’t done it for years. The best time for me to do it was immediately after work, since I could easily get an open swim lane at my local fitness club then.

        Also, swimming became a nice reason for me to leave work on time. And I got to enjoy a nice workout before eating dinner.

        Swimming is a good way to get your cardio or endurance training. But, walking, running and dancing are nice alternatives.

        So find an exercise you love and stick to it. Ideally, get a combination of endurance training, strength training and flexibility training in during your daily 20-minute workout.

        If you haven’t exercised in a while and have a lot of stress in your life, you may want to give yoga a try because you will increase your flexibility and lower your stress.

        A — Attitude

        Stress may be a major reason why you aren’t feeling well all of the time. At least that was the case with me.

        When I worked 70 hours per week as a High-Tech Executive, I felt chronically stressed and exhausted. But there was one thing that always worked to help me feel calmer and less fatigued.

        Do you want to know what that master stress-busting technique was?

        Breathing.

        But not just any old breathing. It was a special form of deep Yogic breathing called the “Long-Exhale Breathing” or “4-7-8 breathing” or “Pranayama” in Sanskrit).

        Advertising

        Here’s how you do “Long-Exhale Breathing”:

        1. Sit in a comfortable position with your spine straight and your hand on your tummy (so you know you are breathing deeply from your diaphragm and not shallowly from your chest)
        2. Breathe in deeply and slowly from your diaphragm with your mouth closed while you count to 4 (ideally until your stomach feels full of air)
        3. Hold your breath while you count to 7 mentally and enjoy the stillness
        4. Breathe out through your mouth with a “ha” sound while you count to 8 (or until your stomach has no more air in it)
        5. Pause after you finish your exhale while you notice the sense of wholeness and relaxation from completing one conscious, deep, long exhale breath
        6. Repeat 3 times ensuring your exhale is longer than your inhale so you relax your nervous system

        This type of “long-exhale breathing” is scientifically proven to reduce stress.

        When your exhale is twice as long as your inhale, it soothes your parasympathetic nervous system, which regulates the relaxation response.[8]

        Plus, this is a great technique for helping you get to sleep, too.

        N — Nutrition

        Diet is vital for beating fatigue – after all, food is your main source of energy.

        If your diet is poor, then it implies you’re not getting the nutrients you need to sustain healthy energy levels.

        Eating a diet for fatigue doesn’t need to be complicated, time-consuming though.

        For most people, it’s just a case of swapping a few unhealthy foods for a few healthier ones, like switching from low-fiber, processed foods to whole, high-fiber foods.

        Unless your current diet is solely made up of fast food and ready meals, adjusting to a fatigue-fighting diet shouldn’t be too much of a shock to the system.

        Here’re 9 simple diet swaps you can make today:

        1. Replace your morning coffee with Matcha green tea and drink only herbal tea within six hours of bedtime.
        2. Add a healthy fat or protein to your any carb you eat, especially if you eat before bed. Please note that carb-only snacks lead to blood-sugar crashes that can make you eat more and they can keep you from sleeping.
        3. Fill up with fiber especially green leafy vegetables. Strive to get at least 25g per day with at least 5 servings (a serving is the size of your fist) of green vegetables.
        4. Replace refined, processed, low-fiber pastas and grains with zucchini noodles and whole grains such as buckwheat, quinoa, sorghum, oats, amaranth, millet, teff, brown rice and corn.
        5. Swap natural sweeteners for refined sugars and try to ensure you don’t get more than 25g of sugar a day if you are a woman and 30g of sugar a day if you are a man.
        6. Replace ice cream with low-sugar alternatives such as So Delicious Dairy-Free Vanilla Bean Coconut Ice Cream.
        7. Swap omega-6, partially-hydrogenated oils such as corn, palm, sunflower, safflower, cotton, canola and soybean oil for omega-3 oils such as flax, olive and nut oils.
        8. Replace high-sugar yoghurts with low-sugar, dairy-free yoghurts such as Kite Hill Plain Yoghurt with 1g sugar or Lifeway Farmer Cheese with 0g sugar.
        9. Swap your sugar-laden soda for sparkling water with a splash of low-sugar juice

        Also, ensure your diet is giving you enough of the daily essential vitamins and minerals. Most of us don’t get enough Vitamin D, Vitamin B-12, Calcium, Iron and Magnesium. If you are low on any of the above vitamins and minerals, you may experience fatigue and low energy.

        That’s why it’s always worth having your doctor check your levels. If you find any of them are low, then try to eat foods rich in them.

        Alternatively, you might consider a high-quality multi-vitamin or specific supplement.

        The Bottom Line

        If you are tired of feeling tired, then there is tremendous hope.

        If you are tired because you are not getting enough high-quality sleep, then the best remedy is a bedtime routine based on sleep best practices.

        If you are tired because you have stress and fatigue, then the best remedy are four simple lifestyle changes including:

        • Enough High-Quality Sleep with Bedtime Routine
        • Regular Exercise You Love
        • Stress Reduction with Long-Exhale Breathing
        • Fatigue-Reducing Diet

        Overall, adopting a healthier lifestyle Is the ideal remedy for feeling more rested and energized.
