Computer Eye Strain and Dry Eye Can Cost You Money, Productivity and Your Vision

1 May

If your eyes often bother you after a couple of hours at the computer, you are not alone. Computer eye strain, a form of dry eye disease, has become one of the most common reasons for eye doctor visits.

Eye health advocate Sharon Kleyne cautions that computer eye strain symptoms should never be ignored. Mrs. Kleyne is host of the Sharon Kleyne Hour Power of Water syndicated radio show, and founder of Bio-Logic Aqua Research.

Sharon Kleyne notes that the tear film of the eye is 99% water and that computer eye strain symptoms usually result from tear film water evaporation. Symptoms include tired, burning or itchy eyes, blurred vision, headaches, poor sleep and elevated stress. The good news, Mrs. Kleyne says, is that with a few common-sense precautions, including the following tips, computer eye strain can be relieved and even prevented.

  1. Have an annual professional eye exam.

  2. Drink at least eight glasses of water every day.

  3. Eat eye healthy foods (dark green leafy vegetables and foods rich in omega-3 fatty acids), exercise and fresh air regularly, and get sufficient sleep.

  4. Keep a hand-held air humidifier, plants and/or an open container of water near your desk. Because the air is dry, adding water (moisture) to the air reduces dry eye and natural water evaporation due to dehydration.

  5. Sip water while you work. Pour bottled water into a glass before drinking.

  6. Try to blink more often, taping a reminder to the computer if necessary. When working at a computer screen, your eyes’ blink rate can drop from 30 times per minute to three times per minute, which increases tear film water evaporation.

  7. Exercise your eye muscles by looking around the room at varying distances several times per hour (Take breaks away from your desk – outdoors if possible. Crack (or open) a window to let in fresh, humid air (indoor air can be dry, stale and dehydrating).

  8. Turn off lights that are too bright, especially fluorescent lights. Or switch to a desk lamp.

  9. Periodically throughout the day, moisturize the air around your eyes with a pH balanced (below 7.0), fine-mist eye spray.

The only all-natural, all-water, hand-held eye humidifying device with patented technology to supplement natural tear film water, is Nature’s Tears® EyeMist® from Bio-Logic Aqua Research, a sponsor of the Sharon Kleyne Hour Power of Water.

Computer Vision Syndrome and Computer Eye Strain

20 Apr

Benefits of Eye Misting for Computer Dry Eye

We know what you’re doing right now!

You’re looking at a computer screen, aren’t you?

And chances are, your eyes are not happy about it!

Computers and dry eye symptoms.

  • Dry eye discomfort from computer use is a growing and increasingly urgent problem.
  • Ophthalmologists call this “computer vision syndrome” (CVS), “computer eye strain,” “computer eye irritation” or “computer dry eye.”
  • The computer dry eye problem is widespread, and potentially serious.
  • Nearly every computer user experiences dry eye discomfort that could lead to loss of productivity, loss of income, and eventually, loss of eyesight

Do you have computer vision syndrome?

If you answer “yes” to question #1 and at least two others, you may be experiencing computer vision syndrome.

  • Are you a “Computer Nerd” who uses a computer more than two hours a day?
  • Do your eyes sometimes burn or itch?
  • Are your eyes sometimes sensitive to light?
  • Does your vision ever become blurry?
  • Do your eyelids sometimes become heavy or tired during computer use, even though you’ve had plenty of sleep?
  • Do you get headaches from using the computer?
  • Do your shoulders sometimes feel tight while using the computer?
  • Do you have frequent eye allergies?

Other causes of computer vision syndrome:

In addition to computers, several common office conditions could result in computer eye strain, tear film dehydration and dry eye symptoms.

  • Forced-air heating and cooling.
  • Synthetic chemicals (plastics, paint, cleaning fluids, etc).
  • Insulated windows and walls.
  • Fluorescent lighting.
  • Stress.
  • Low indoor humidity.
  • Your diet.

Your eyes depend on the tear film.

  • The highly complex “tear film” covering the eyes consist of water, oil, electrolyte, antibodies, protein and mucus. The tear film moistens, lubricates, oxygenates and protects the eyes; and forms a light transmitting surface that enables you to see.
  • The tear film is 98% water. Every time you open your eyelids, you expose the tear film to evaporation and natural water loss.
  • Dry eye symptoms occur when too much water evaporates from the tear film without replacement (this process is highly complex, also involving tear glands and brain messaging).
  • More dry eye education
  • More tear film education
  • Computers accelerate tear film dehydration and water evaporation because:
    • They create or reflect glare and intensely bright light.
    • They are almost always indoors, which tends to be less humid than outdoors.
    • They cause a decreased blink rate (blinking replenishes the tear film), which may drop from 30-40 times a minute to three times a minute.
    • They contribute to brain and body stress, which is dehydrating.
  • To re-hydrate dry eyes, simply add water to the dehydrated tear film!
    • Formulated eye drops are inconvenient to apply, excessively large in volume, contain little natural water and are not always effective.
    • Nature’s Tears EyeMist instantly and conveniently replaces lost tear film water.

Nature’s Tears EyeMist.

To supplement tear film water and minimize dry eye symptoms, mist your eyes frequently with Nature’s Tears EyeMist. With no dosage limit, all-natural Nature’s Tears EyeMist may be applied whenever computer dry eye symptoms are experienced. Always keep Nature’s Tears EyeMist beside your computer (and combine it with a complete daily hydration program that includes drinking 8-10 glasses of water a day).

Computer vision syndrome prevention tips:

  • An eye care professional may prescribe special “computer glasses.”
  • Keep a glass of water (And Nature’s Tears EyeMist) near your desk to help humidify the air.
  • Drink bottled water while you work…but pour it into a glass first. Total daily water intake should be at least 8 to 10 glasses.
  • Make a conscious effort to blink more often.
  • Several times per hour, look around the room at objects of varying distances.
  • Take scheduled breaks away from your desk (outdoors if possible).
  • To reduce glare, position your computer so windows are at the side of your computer rather than in the front or back. Adjust window blinds accordingly.
  • If possible, turn off fluorescent overhead lights and switch to a desk lamp.
  • Attach a glare-blocking hood or filter to your monitor.
  • Crack a window to let in humid air from the outside. Outdoor air is free of re-circulated bacteria and shed skin particles from co-workers, which enters via the heating/cooling system and can cause eye and skin dehydration.
  • Set the REFRESH RATE on your monitor as high as you can (over 85). Use a flat-screen if possible. A low refresh rate (60 or less), on a cathode ray monitor, can cause dry eye, eye strain and headache.
  • Take a shower every day that allow plenty of steam and water to penetrate your eyes, skin, breathing passages and lungs.
  • Every couple weeks, take a long, luxuriant hot body bath with a cup of Epsom salt dissolved in the bathtub water. This will detoxify, lubricate and humidify dry eyes and skin, improve skin flexibility and benefit all part of the body.
  • Keep your body fit: Reduce stress, establish a daily program of sleep, fresh air and exercise, control your weight, avoid sugar (which is dehydrating) and eat lots of dark green leafy vegetables (eye food).

Tips to Prevent Computer Eye Strain and Computer Dry Eye

6 Apr

Since March, 2007, the Sharon Kleyne Hour Power of Water radio talk show has interviewed numerous guests who offered tips to prevent “computer eye strain” (also called “computer vision syndrome,” “CVS,” or computer eye strain). Symptoms are experienced by a surprisingly large percentage of people who work at computers.

Computer eye strain and dry eye symptoms should never be ignored. Dry eye symptoms could lead to chronic dry eye, eyelid inflammation, corneal ulceration, impaired vision and numerous eye diseases. Symptoms include red, burning and itchy eyes, blurred vision, eye twitching, headaches and impaired sleep.

Vision care experts agree that the #1 tip to prevent or minimize computer eye strain is educating yourself about the problem. The #2 tip is taking personal responsibility to proactively implement the eye care tips described below.

The #3 tip for keeping eyes all-naturally wet, moist and humid is to always have Nature’s Tears® EyeMist® near your computer. Apply as often as desired without the inconvenience of eye drops (Eye drops, applied too frequently, can flood and wash away the eye’s natural tear film. See http://www.naturestears.com and click on “Dry Eye”). Nature’s Tears EyeMist, a personal hand-held eye humidifying device, is all-natural tissue culture water, pH balanced and 100% safe.

Tips to prevent and minimize computer eye strain.

In addition to preventing computer eye strain and dry eye, many of these tips help prevent other computer related conditions such as gout, allergies, carpal tunnel syndrome and weight gain (abdominal swelling).

  • Keep an all natural, 100% water eye mist beside your computer. Whenever you feel eye discomfort, mist the air in front of your eyes for two seconds. Sharon Kleyne recommends Nature’s Tears EyeMist for this, available on http://www.Amazon.com or http://www.naturestears.com.
  • Drink eight to ten glasses of water a day and drink water from a glass while you work.
  • Keep a bowl of water or a plant near your desk to humidify the air. Crack a window to let in fresh, humid air from the outdoors (forced-air heating and cooling re-circulates dehydrating bacteria and skin flora).
  • “Eye Healthy” diet choices include dark green leafy vegetables (spinach, kale, arugula, broccoli leaves), foods with omega-3 fatty acids (fish and flaxseed oil) and carrots.
  • While working, avoid dehydrating substances such as alcohol, coffee, energy drinks, refined sugar products and cigarette smoke.
  • Avoid staying up late at night on the computer if you will be working at a computer in the morning.
  • Several times per hour, to relax and exercise your eyes, look around the room at objects of varying distances. Take scheduled breaks away from your desk, outdoors if possible.
  • Make a conscious effort to maintain your blink rate (computer use can drop your reflexive blink rate from 30 to three times a minute). Tape the word “BLINK” on your monitor. The more you blink, the moister your eyes.
  • Position your chair as high as possible with respect to the monitor. The resultant lowering of eyelids can drastically reduce tear film moisture evaporation.
  • To reduce screen glare, position your computer so windows are at the sides rather than in front or back. Adjust window blinds so bright sunlight is away from screen and eyes. If possible, turn off fluorescent lights and use a less intense desk lamp.
  • An eye care professional may prescribe special “computer glasses” or, for severe dry eye, moisture retaining eyeglass lenses.
  • Wear sunglasses outdoors – solar radiation dehydrates the eyes.
  • If you have a cathode tube monitor, consider attaching a glare-blocking hood or filter to the screen and set the “Refresh Rate” as high as you can (over 85).
  • Take daily showers with plenty of steam and moisture penetrating eyes, skin and breathing passages. An occasional hot body bath with a cup of Epsom salt. Will benefit eyes and eyelids and reduces stress.
  • Avoid stress and get adequate sleep and fresh air exercise. Poor sleep and elevated stress can be dehydrating and cause dry eye symptoms.

Laser Eye Surgery Pioneer Marguerite McDonald, MD, Talks Computer Eye Strain

10 Nov

Laser Eye Surgery Pioneer Marguerite McDonald, MD, in addition to performing the world’s first excimer laser eye surgery in 1986, is a practicing Ophthalmologist on Long Island and Professor Emeritus at Tulane University. As a practicing Ophthalmologist, she has considerable experience treating dry eye, computer eye strain and computer dry eye.

On June 1, 2009, Dr. Marguerite McDonald was interviewed on the Sharon Kleyne Hour Power of Water, an Internet radio talk show hosted by Sharon Kleyne. The interview may be heard on World Talk Radio, Voice America, Green Talk Network, Apple iTunes and Amazon.com.

Computer Eye Strain

Dr. McDonald observed that computer eye strain is a common and rapidly growing complaint among her patients and that the number of patients who can no longer use computers as a result of computer eye strain and serious dry eye symptoms is also growing rapidly. Symptoms should always be taken seriously and alleviated when possible, both by soothing the eyes and by taking prevention measures.

Soothing computer eye strain

Dr. McDonald notes that rubbing is bad for your eyes. If dryness or itching of the eyes is caused by allergies, rubbing can further entrench the allergen and cause a release of chemicals that are even more uncomfortable.

For dry eye symptoms, Dr. McDonald recommends a cool, wet compress, lying down and relaxing, with eyes closed. Moisture from the compress will absorb into closed eyes and eyelid skin. Dr. McDonald also recommends Nature’s Tears EyeMist (a sponsor of the Sharon Kleyne Hour Power of Water) to soothe dry eyes. While performing eye surgery, Dr. McDonald has her eyes misted occasionally.

Predisposition

Dr. McDonald pointed out that many factors can predispose computer users to develop dry eye and computer eye strain symptoms. These include arthritis, Parkinson’s, scleroderma, Sjogren’s syndrome, allergies, numerous medications (especially blood pressure medications and anti-depressants), osteoporosis, gout, blink disorders, thyroid problems and the first few days after LASIK eye surgery.

Other factors affecting tear film moisture content during computer use include common office conditions such as indoor air, forced-air heating and cooling, cleansing fluids, detergents, poorly ventilated buildings and excessive computer use.

Preventing and alleviating

According to Dr. McDonald, the most serious eye problem associated with computer use and computer eye strain is reduced blink rate. The normal blink rate is 20 to 30 times per minute whereas somebody deeply absorbed in computer work may blink only three times a minute. This greatly increases moisture evaporation from the eye.

Dr. McDonald suggests keeping the computer screen low so that you have to look slightly down on it and therefore do not open your eyes as widely. She also recommends frequent short breaks to rest the eyes and regular breaks away from the computer. Also important are sleep, stress reduction, exercise, adequate daily water intake and a proper diet including eye foods such as dark green leafy vegetables and foods with omega-3 fatty acids. .

Be Alert for Pet Dry Eye and Be Sure Your Dog or Cat Drinks Enough Water

“Dry eye in humans is often environmentally related and has become the number one reason for United States eye doctor visits. Pets are subject to the same environmental conditions and are far more prone to eye injuries and diseases, including cat and dog dry eye. As a pet “parent,” monitoring your dog or cat’s eye health is critical. Eyes should always be kept moist and, of course, you must make sure your dog or cat eats properly and drinks enough water.”

Sharon Kleyne, syndicated radio talk show host*

The state of eye care in pets.

According to Animal Eye Care, which runs 39 ophthalmology clinics for pets, dogs and cats are subject to numerous eye diseases. The list on their website includes blepharitis, eye injuries, cataracts, conjunctivitis, corneal ulcers, eyelid masses and glaucoma.

Sharon Kleyne, entrepreneur, water and health advocate, and host of the Sharon Kleyne Hour -Power of Water syndicated radio talk show, points out that nearly all of these eye diseases are either the result of pet dry eye (a disease characterized by insufficient water content in the protective natural tear film covering the eye), or have pet dry eye as a side effect (Pet dry eye often results from diet and/or medication).

She reiterates what many veterinarians are discovering – that treatment of these diseases will be far more effective if you simultaneously treat for cat or dog dry eye.

Cat and dog dry eye.

Sharon Kleyne’s research has discovered that eye dehydration and dry eye disease among humans are more widespread than commonly reported (nearly every human suffers from occasional dry eye symptoms and it usually goes undiagnosed). “If dry eye is under-diagnosed among humans,” says Mrs. Kleyne, “the condition is almost unrecognized among professional pet care experts – despite the fact that the incidence of dry eye may be even greater among dogs and cats than among humans.”

“The good news,” according to Mrs. Kleyne, “is that there are many ways pet owners can be proactive in monitoring their pet’s eyes to keep them hydrated and healthy.

(Note: Because of the “third eyelid” membrane, a normal dog or cat eye is slightly better protected and better moisturized than a human eye. But because pets are exposed to far more high risk situations, their eyes are more subject to injuries and infections.)

Dry eye symptoms

Pet dry eye in is closely linked to conjunctivitis, red eye, blepharitis (eyelid inflammation) and corneal ulcers. Symptoms may include: (1) redness of the white part of the eye, (2) eyelid inflammation, (3) frequent eye infections and dripping, (4) lack of “shine” in the eyes or a noticeable thickening or unevenness of the tear film’s usually invisible lipid (oil) component, (5) indications of eye discomfort such as frequent squinting, blinking or pawing at the eyes, (6) unusual dryness of the fur and/or mouth.

Environmental risk factors include; (1) living in an extremely dry or desert climate, (2) frequent exposure to wind, cold and solar radiation, (3) frequent exposure to dirt (very common among dogs), dust, smoke or chemical fumes, (4) prolonged exposure to climate controlled indoor environments such as forced-air heating and cooling and insulated walls and windows.

High risk dog breeds: bulldogs, cocker spaniels, lhasa apsos and west highland white terriers.

 

Suggestions for pet eye care, including cat and dog dry eye.

  • Control exposure to high risk situations.
  • Inspect your pet’s eyes frequently, watching for symptoms described above and for symptoms of other eye diseases.
  • See your veterinarian if your pet shown any symptoms of any eye disease, including dry eye.
  • For mostly indoor pets, make sure their home is well-humidified. Open windows, have lots of plants around, set out bowls of water or purchase a room humidifier.
  • Make sure your pet is well nourished and drinks enough water every day.
  • Apply Nature’s Tears EyeMist several times a day to maintain natural tear film water content and also to keep fur well hydrated. This routine can prevent or alleviate dry eye and help reduce dry eye as a side effect of other diseases.

Suggestions for pet watering.

Pets vary in the amount of water they like to drink and getting them to drink more can be a challenge. Do not assume that they will drink the exact right amount of water “by instinct.”

  • Pets should drink one cup of water per day for every 10 pounds of weight.
  • Follow the recommended diet for your pet’s species, age, weight, state of health and lifestyle.
  • Water sitting in a bowl all day can become contaminated and also lose oxygen and therefore taste.
  • Change water bowl frequently or purchase a pet watering device.
  • Don’t let pets drink from puddles or lakes.
  • Add water to your pet’s food.
  • Offer them water occasionally – especially after activity.
  • Pets require more water if they are ill.

Preventing and Lessening Eye Injuries

13 Jun

Eye Protection and Emergency First Aid

Note: According to the Merriam-Webster Medical Dictionary (1995), “to injure” is defined as, “to impair the soundness of.” Based on this extremely broad definition, the term “eye injury,” as used by eye care and emergency professionals, can refer to conditions ranging from the mildly uncomfortable (soap in the eye or squinting due to air pollution) to catastrophic trauma (eye penetration by a foreign object).

Eyesight Threats.

” In an emergency, eyesight threats may arise from smoke, heat, dust, fumes, airborne chemicals and particles, perspiration into the tear film, tear gas and pepper spray, mechanical injuries and impact trauma from flying objects. Injuries from of these threats may often be prevented or lessened through good eye safety practices.

” Eyesight threats may also be present in non-emergency situations. They could be caused by cleaning fluid fumes, auto exhaust, slicing onions, prolonged computer use, perspiration into the tear film, an eyelash in the eye, home shop accidents, and even insulated windows and walls and forced-air heating and cooling (which can be dehydrating to the eye’s protective tear film). These injuries may also be prevented or mitigated with good eye safety practices.

” Unprotected exposure to these eyesight threats could result in consequences ranging from mild eye discomfort to serious and permanent eye damage. Symptoms could include blurred or impaired vision, pain, dehydration (dry eye), eye strain; burning, itchy or watery eyes; eye diseases and serious physical injury (catastrophic trauma). Symptoms may be mild (sub-acute) or temporarily disorienting, or they could result in permanent eye damage and eyesight impairment or loss.

Eye Protection and First Aid.

  • Remember that in an emergency such as a burning building, impaired eyesight from dust, smoke, fumes or perspiration, could make it more difficult or impossible to get out and could cost you your life.
  • Healthy, well hydrated eyes will serve you far better in an emergency. It pays to educate yourself about eye care and practice good eye health on a daily basis.
  • Before engaging in an activity where eye injuries could occur, always:
    • Know what to do in an emergency.
    • Have a predetermined emergency first aid plan for eye and other injuries.
    • Follow good safety precautions and procedures.
    • Have emergency first aid materials available.
  • The best way to prevent eye injuries, especially from foreign objects and harmful substances, is to wear protective eyewear when in high risk situations. If you have corrective lenses, you are less likely to have an accident if you wear them.
  • Chronically dehydrated eyes, which lack sufficient moisture (water) in the protective overlying tear film, are more susceptible to certain eye injuries than fully hydrated eyes.

Specific Situations.

Fumes, smoke, tear gas, pepper spray, airborne chemicals. These conditions can make it difficult or impossible to see in an emergency and may cause permanent damage. They can also create discomfort by altering the tear film’s pH (acidity/alkalinity), osmolarity (moisture attracting ability) and moisture content. Protective eyewear helps shield eyes from certain airborne irritants. Should discomfort become extreme, irrigate eyes with a sterile eye wash spray such as Bio Med Wash, other eye wash devices, or water from a plumbed eyewash station.

Chemical or thermal burns to eyes, eyelids or skin. Spray or irrigate eyes with copious amounts of water or liquid (Bio Med Wash spray, other eye wash devices or a plumbed eyewash station). Do not blot burned areas unless caused by a chemical, such as pepper spray or tear gas that will continue to burn unless removed. If injury is severe, bandage and seek immediate medical assistance. Keep burned areas moist by spraying with a water mist. (Note: Some chemical eye washes may compound the negative effect of harmful chemicals.)

Perspiration and sunburn. Solar exposure is dehydrating to both eyes and skin and could increase perspiration run-off into the eyes, thus increasing the tear film’s salt concentration and causing discomfort. Sunburn is extremely dehydrating to eyes, and to eyelid skin that protects the eyes. Drink plenty of water during extended solar exposure or during situations that make you perspire. Water with added salt is best (a Gatorade type drink). The amount of needed water increases with temperature and activity level, but eight glasses per day are recommended. Moisturize eyes and skin with a water eye and facial mist and by drinking plenty of water.

Foreign objects (catastrophic trauma). For small objects such as sand or metal filings, irrigate and flush the affected eye with copious amounts of water, from either an all-water eye spray, plumbed eyewash station or other eye wash system, until the object(s) is removed. If there is (or if you suspect) penetration, severe pain, profuse watering or corneal scratching, bandage the eye and seek medical attention. Do not try to wash out particles that have penetrated the corneal membrane.

Contact lenses. For most eye injuries, if there is a contact lens in the eye, leave it place while flushing, irrigating or bandaging. Remove the lens only when first aid treatment is completed and the eye begins to feel normal.

Eye strain, stress, fatigue and allergies can cause body, eyes and skin to lose moisture and cause eye discomfort. Moisturize the eyes with a water mist and by drinking plenty of water.

Low humidity, heat, cold and wind increase moisture evaporation from the body’s external surfaces (eyes, skin, breathing passages) causing skin chapping, eye discomfort, dry eye, etc. Low humidity may become an eye threat in both warm and cold weather. Moisturize the eyes with a water mist and by drinking plenty of water.
