Computer Vision Syndrome

Learn how to recognize and prevent eye problems associated with extended computer monitor use.

As you read this article right now, your eyes are working harder than they would if you were reading a book or even watching TV. Attention, desk warriors! If you stare at a computer for most of the day, you could leave work experiencing dry eyes, headaches, and blurred vision. 90% of people who work on a computer experience symptoms of Computer Vision Syndrome, or CVS. Symptoms include blurred vision, dry eyes, headaches, eye strain, irritation, redness, and any number of other ocular symptoms.

Computers have become a necessity in our world, so monitors are here to stay. Here are some of the causes of CVS and some tips to help you protect your eyes from the screen:

  • Blinking. One of the main symptoms of CVS is eye dryness. This occurs for two reasons: First, your eyes are focusing on the same depth of field for an extended period of time; second, unlike the non-stop action on a TV screen, there may be little movement happening on your computer screen. The lack of movement and constant field depth leads to less blinking and, therefore, eye dryness.
    Fix it
    by spending 30 seconds every hour or so adjusting your eyes to something far away. If you work in a small office, put up a picture and focus on something small in the background. This change in depth of field will exercise your eyes, and you’ll blink more!
  • Monitors. The pixels on a computer screen can cause some problems. Because they are not all the same brightness, they don’t produce the same contrast. And they can cause words or pictures on the screen to look fuzzy, straining your eyes and contributing to CVS.
    Fix it
    by investing in a good LCD monitor if you have not done so already. LCD monitors reduce glare and contrast, as compared with older types of monitors. If you already have an LCD monitor, then talk to an ophthalmologist about getting some reading glasses to help reduce eye strain. Adjusting the lighting in the room and/or on your computer screen can also help soften the symptoms of CVS.
  • Existing vision problems. You may already have a vision problem that went undiagnosed until you started staring at a computer. Extended computer use can exaggerate already existing eye conditions and lead to some of the symptoms of CVS.
    Fix it
    by talking to a physician about corrective lenses. The Vision Center of Excellence has excellent resources from the VA and DoD for vision support.

In summary: Protect your eyes from CVS by taking frequent breaks from the computer, by blinking more often, and by making sure you work in an ergonomically efficient office setup. If you want to more information about CVS, check out “A Survival Guide to Computer Workstations.”

Unchecked anger – take a few tips from HPRC

Anger’s a normal emotion, but unchecked anger can wreak havoc. Here are some tips for how to manage your anger effectively.

Anger can be helpful in combat situations, and it can help individuals engage in quick, decisive action. It also can help keep emotions such as guilt and sadness at bay so you can accomplish things you need to do. Anger has its place. In relationships, anger is bound to make its way into interactions sometimes. When regulated, it can help you solve problems or motivate you to talk about important things, including hurt feelings. When unregulated, however, it can damage your relationship and increase your unhappiness with your loved one. Increased levels of anger can even increase your risk for physical health problems, especially coronary heart disease. It isn’t possible to avoid anger completley, but you can learn how to manage it well. Read more in HPRC’s “Performance Strategies: Five Steps to Managing Anger.”

Got pain on your brain?

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Pain is not just in your head, but your head plays a role. Holistic treatment that also addresses your mind may be your best bet in facing pain.

Pain can be unpredictable, uncontrollable, and unrelenting, so even the most resilient Warfighters can be vulnerable to it. Because of pain, you may experience symptoms of anxiety or depression; your mind may even exaggerate the intensity and awfulness of pain. Socially, you might experience criticism, rejection, and negative interactions with family, spouse, or peers. Even if interactions are generally positive, you may want to withdraw from people or difficult situations

Chronic pain, which lasts longer than three months and is unresponsive to treatment, can affect quality of life for many. At least 100 million adults in the U.S. suffer from chronic pain. Unfortunately, combat and other situations make Warfighters especially susceptible to experiencing injury and pain. One study of an infantry brigade found that three months after return from Afghanistan, 44% of the soldiers reported chronic pain.

The American Psychological Association has shared evidence that relief from pain is more likely when mind and body are both treated. The National Center for Complimentary and Alternative Medicine has also indicated that continued study of non-drug approaches to pain management is a priority.

The latest trend in treating pain is the “biopsychosocial model,” which focuses on exercise and sleep (not just meds and surgery) as important biological influences. Important psychological factors include thoughts, emotions, behaviors, and attention. And impactful social factors involve healthcare, family, and work. All of these factors can contribute to understanding and mitigating the impacts of pain.

The American Psychological Association shares concrete advice to manage pain, including these tips:

  • Distract yourself.
  • Stay active and exercise.
  • Know your limits.
  • Follow prescriptions carefully.
  • Make social connections.
  • Don’t lose hope.

Don’t be a boob!

October is Breast Cancer Awareness month. Learn about early detection and prevention.

October is Breast Cancer Awareness month; but what’s important is that, after October is over and the sea of pink has ebbed, you turn your awareness into action if you haven’t done so already. Gentlemen take note: Men can get breast cancer too. Early detection can be critical for dealing with breast cancer. Make sure you conduct regular breast self-exams. If you find anything that worries you, talk to your doctor right away.

While your genetics play a role in the development of some breast cancers, exercise is also an important lifestyle tool to reduce your risk for this and other cancers such as lung and colon cancer. It may even improve your chance of recovery if you’ve already been diagnosed. Numerous studies have found that regular exercise can reduce your risk for breast cancer by an average of 25%.

It’s never too late to start getting active. While exercise at any age can reduce your risk for breast cancer, the greatest benefit seems to be for adult women, especially those over the age of 50. It’s important to be physically active throughout the day, not just when you’re exercising. Studies have shown that sitting and other sedentary behaviors for long periods of time can negate the effects of regular exercise, for general health and cancer prevention. The good news is that household and recreational activities, followed by walking/cycling and occupational activities, have the greatest impact on reducing risk for breast cancer.

Exercise and physical activity during cancer treatment also can be healthy for mind and body, can manage fatigue, and may lower the risk of progression. If you have already been diagnosed with breast cancer, talk to your doctor about what kinds of activities are safe for you to do while undergoing treatment. Just another reason to get out and get active! 

Take the day off and celebrate the Navy’s birthday!

HPRC Fitness Arena: Total Force Fitness
Filed under: Navy, Service branches
Columbus Day this year falls on the 239th birthday of the U.S. Navy. Was Columbus really in the Navy?

As you probably know, Columbus had ships. And the Navy has ships. And both had something to do with the birth of the United States of America. After that, any connection is a bit of a stretch. After five weeks at sea, Columbus made first landfall in the Americas on 12 October 1492 on an island in the Bahamas. In 1937, Columbus Day became a federal holiday, and since 1970 it has been on the second Monday in October.

The Second Continental Congress—the group that governed during the American Revolution and eventually passed our Declaration of Independence in 1776—created the Continental Navy in 1775. It began by authorizing two armed ships and crews to destroy munitions ships that provided supplies for the British Army in America. During the war, the Navy deployed as many as 20 warships at a time. Following the war, Congress sold the remaining warships and released their crews.

However, the new Constitution of the United States included instructions “to provide and maintain a navy,” so in 1794 the War Department oversaw the construction and manning of six new ships, and on 30 April 1798 Congress established the Department of the Navy. The United States Navy has existed continuously since then. Despite this second “birthday,” in 1972 the Chief of Naval Operations established 13 October as the officially recognized anniversary. For interesting facts, articles, activities, and more, check out the official “Navy Birthday” web page. And find something fun to do! After all, thanks to Columbus, this year it’s a holiday!

Crazy for coconut water?

HPRC Fitness Arena: Nutrition, Total Force Fitness
Coconut water is touted as a “natural” drink and a possible alternative for rehydration, but you may need additional nutrients during strenuous exercise.

Coconut water, the flavorful liquid found in young green coconuts, has become a popular drink. It is often promoted for a variety of ailments—from curing bad skin to resolving hangovers. But coconut water is also touted as a fluid replacement alternative. For this reason, some Warfighters choose coconut water over sports beverages because coconut water is “natural” and contains carbohydrates and key electrolytes such as sodium and potassium. However, not all brands of coconut water are created equal. In fact, they can vary considerably in terms of their nutrient content, so read product labels to be sure you’re getting the right amounts of nutrients you need for optimal performance. In addition, many kinds of coconut water contain fruit juice for flavor, which can increase the sugar and calorie content of the drink.

One of the biggest appeals of coconut water is its naturally high potassium content. While the potassium content is high, the amounts of carbohydrate and sodium in coconut water are sometimes very low, and individuals who participate in prolonged, vigorous exercise (longer than an hour) may need more carbohydrate and sodium for proper hydration. For more information about hydration needs, see HPRC’s article on fluids and exercise.

For periods of exercise less than one hour, water is always your best choice—about 3–8 ounces every 15–20 minutes. But for longer periods of exercise, sports beverages are a good choice because they are specially formulated to replenish carbohydrate, sodium, and potassium lost during extended and/or vigorous physical activity. If you choose sports beverages, drink 3–8 ounces every 15–20 minutes to stay hydrated. Again, be sure to read the product label to make sure your drink has what you need, and nothing more. For more information about proper fueling, read An Athlete’s Guide to Nutrient Timing.

And what about that coconut water? There simply isn’t enough evidence to support the use of coconut water as a remedy for any condition. And although it’s a tasty beverage, know what’s in it so you can replenish what your body needs—no more, no less.

Organic foods: Are they worth the cost?

HPRC Fitness Arena: Nutrition, Total Force Fitness
We all see organic foods at the store, hear people talking about them, and may make the choice to purchase and eat organic foods. But is all the hype about the benefits worth the cost?

Many of us have seen foods labeled as organic, but most people don’t know what that means. In order to be considered organic, foods must be certified by the United States Department of Agriculture (USDA) and meet certain standards. Generally, organic foods must be produced without the use of any artificial fertilizers, pesticides, growth hormones, antibiotics, sewage sludge, or genetically modified organisms. As a result, organic foods have become quite popular.

Because of the differences in production, organic foods tend to be more expensive than conventional foods. For example, the average price of a gallon of regular milk is $2.89, but the average price of a gallon of organic milk is $5.99. That’s more than double the cost, which may not be affordable for many people. For military families who prefer to buy organic foods, discounted prices may be available at their local commissary. Ask grocery stores and wholesale stores about military discounts and coupons. For those who qualify, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) allows organic fruits and vegetables to be purchased with cash-value vouchers. The eligibility of other foods is state-dependent, and each state’s approved food list can be found on USDA's WIC page.

The price difference between organic and conventional foods is clear, but the benefits of choosing organic are not as obvious. Organic foods are thought to be better for the environment and our bodies. However, from a nutritional standpoint, there is not enough evidence to suggest a clear benefit to purchasing organic foods over conventional foods. If pesticides are your concern, visit the Environmental Working Group website to learn more.

So, the next time you’re trying to decide between organic and non-organic, remember that nutritional differences don’t need to be a major factor in your decision because there don’t appear to be any. A diet rich in fruits, vegetables, and whole grains is beneficial no matter which option you choose.

For more information on organic foods, check out USDA's website.
