  • Eyestrain From Computer Use

    Eye Conditions

    Persons who use computer video display terminals (VDTs) at work and/or at home may notice eyestrain.

    Signs & Symptoms

    *  Eye discomfort or irritation. This includes dry, red, and/or watery eyes.

    *  Eye fatigue.

    *  Having a hard time focusing.

    *  Back pain, shoulder pain, and headaches may also occur.

    Causes

    The cause of eyestrain is most likely from conditions that surround the VDT, not the VDT itself. These include improper positioning of the VDT and supplies, poor lighting, and/or poor posture.

    A pre-existing eye problem may also be the cause.

    Treatment

    Self-care measures prevent and treat eyestrain when using VDTs.

    Questions to Ask

    Self-Care / Prevention

    *  Place the screen so that your line of sight is 10 to 15 degrees (about one-third of a 45-degree angle) below horizontal.

    *  Position the VDT screen about 2 feet away from your eyes. This is a little farther away than normal reading distance.

    *  Dust the screen often.

    *  Reduce glare. Place the VDT at right angles to a window. Turn off or shield overhead lights. Wear a visor to block them, if needed.

    *  Place your paperwork close enough that you don’t have to keep refocusing when switching from the screen to the paper. Use a paper document holder placed at the same height as the VDT screen.

    *  Blink often to keep your eyes from getting dry. Use “artificial tear” eyedrops, if needed.

    *  Tell your eye specialist that you use a VDT. Glasses and contacts worn for other activities may not be good for VDT work. With bifocals, the near-vision part of the lens is good for looking down, as when you read, but not for looking straight ahead, as when you look at a video display screen. You may need single-vision lenses for VDT work.

    *  If the image on the VDT screen is blurred, dull, or flickers, have it serviced right away.

  • Pop The Cork, Not Your Eye

    WELL-BEING

    Image of cork popping from a champagne bottle.

    Americans will consume more than a billion glasses of champagne during holiday and New Year celebrations. According to the American Academy of Ophthalmology, the careless handling of champagne is one of the most common causes for holiday-related eye injuries. These injuries are often caused by improperly opening the bottle, as a champagne cork is just less than 90 pounds of pressure-3 times the pressure inside a car tire.

    The Korbel Champagne authorities offer this advice:

    *  The recommended way to properly open a bottle is to ease the cork out slowly, with the sound of a gentle sigh-not a pop, which wastes champagne.

    *  Make sure your champagne is chilled and unshaken. Chill the bottle for at least 4 hours in the refrigerator (a warm bottle is more likely to pop).

    *  Remove the foil cap covering the top of the bottle, exposing a wire hood.

    *  Undo the wire hood with 6 half-turns of the knob.

    *  Hold the bottle at a 45-degree angle while holding the cork firmly with one hand and the base of the bottle with the other. Be sure to point the bottle away from your guests.

    *  Do not twist the cork. Rather, turn the bottle slowly while letting the cork glide out gently, emitting a gentle sigh.

    *  In the did-you-know department: There are more than 50 million bubbles in a standard bottle of champagne.

  • Floaters & Flashes

    Eye Conditions

    Signs & Symptoms

    *  Floaters are specks, dots, cobwebs, or wavy lines that seem to fall within the line of sight. They rarely affect eyesight. They are more visible against a plain or dark background.

    *  Flashes are streaks of light that “flash” across the field of vision. They can occur when the eyes are closed or in extreme darkness.

    Causes

    With aging, the middle portion of the eye, called the vitreous, becomes less solid and more liquid. This allows particles (floaters), which have always been in the eye, to begin to move around. Flashes can occur when the vitreous shrinks and pulls on the retina of the eye. This is common. On rare occasions, when the vitreous detaches from the retina, it can rip or tear the retina. This may lead to a detached retina. The retina peels away from the eye wall causing sight loss.

    Risk Factors for Floaters and Flashes

    *  Eye diseases or injuries.

    *  A tear in the retina. Aging and cataract surgery increase the risk for this.

    *  High blood pressure.

    *  Migraine headaches.

    *  Nearsightedness.

    Treatment

    Self-care is enough to treat floaters and flashes unless they are due to another medical condition.

    Questions to Ask

    Self-Care / Prevention

    *  Move your eyes up and down (not side to side) several times.

    *  Don’t focus on or stare at plain, light backgrounds, such as a blank pastel wall or the light blue sky.

    *  You may notice flashes less if you avoid moving suddenly, don’t bend over, and don’t get up quickly from sitting or lying down.

  • Prevent Vision Loss

    SELF-CARE CORNER

    Image of older man getting an eye exam.

    Glaucoma is a leading cause of irreversible blindness. When glaucoma is treated in its early stages, vision loss can be prevented. Yet studies show that more than half of people with glaucoma don’t use their medications properly.

    The American Academy of Ophthalmology offers this advice:

    *Be honest with your eye doctor about your medication difficulties.Missed a dose? It may not seem to matter much, but research shows that skipping doses can cause your glaucoma to become more severe. Ask about the best way to make up for a missed dose and how to manage your medications.

    *Use memory aids.The most common reason for not taking eye drops is forgetfulness. Try simple memory aids like linking your eye drop schedule to other things you do routinely such as brushing your teeth. Mark times you take your medication on a calendar. Set an alarm on your smartphone.

    *Perfect the “pocket.”Giving yourself eye drops can be challenging. In fact, research has shown that nearly 30% of people taking glaucoma medication are not properly applying their eye drops. Gently pull and pinch the lower lid to make a pocket to catch your drops. Once the drops are in, close your eyes (do not blink) and apply pressure to the point where the lids meet the nose for 2 to 3 minutes. Maybe a loved one can help you apply the drops at home.

    Who’s at risk for developing glaucoma?

    Risk factors include age, family history of glaucoma, African-American and Hispanic-American ancestry, diabetes, and past eye injuries. The American Academy of Ophthalmology recommends that all people get an eye exam by age 40, especially those who have a higher risk of glaucoma.

  • Glaucoma

    Eye Conditions

    Glaucoma is a group of eye diseases that damages the optic nerve and causes vision loss.

    Signs & Symptoms

    For Chronic (Open-Angle) Glaucoma

    This type takes place gradually, and causes no symptoms early on. Loss of side (peripheral) vision and blurred vision are the first signs.

    Later, symptoms include:

    *  Vision loss in side and central vision, usually in both eyes.

    *  Blind spots. Seeing halos around lights.

    *  Poor night vision.

    *  Blindness, if not treated early.

    For Acute (Angle-Closure) Glaucoma

    This type is a medical emergency! These symptoms occur suddenly:

    *  Severe eye pain and nausea.

    *  Blurred vision. Seeing halos around lights.

    *  Redness in the eye. Swollen upper eyelid.

    *  Severe headache that throbs.

    Causes

    Glaucoma occurs when the pressure of the liquid in the eye gets too high and causes damage to the optic nerve. Increased eye pressure without damage is not glaucoma, but increases the risk for it. Antihistamines and long-term corticosteroid use can trigger or worsen glaucoma.

    Risk Factors for Glaucoma

    *  Being over age 60, especially Mexican Americans.

    *  Being African American over age 40.

    *  Having a family history of glaucoma.

    *  Having diabetes.

    *  Being nearsighted.

    Treatment

    Treatments help with current vision. They do not improve sight already lost from glaucoma. Glaucoma may not be preventable, but the blindness that could result from it is. Get tested for glaucoma when you get regular vision exams. If pressure inside the eyeball is high, an eye doctor will prescribe treatment. This includes:

    Medicines used for acute glaucoma are prescribed for life. If medicines do not control the pressure, your doctor may advise:

    *  Laser beam surgery.

    *  Surgery that drains fluid from the eye.

    *  Medicines. These are the most common early form of treatment.

    – Prescribed eye drops or pills lower eye pressure, cause the eye to make less fluid, or help drain fluid from the eye.

    – Take medicines on a regular basis.

    – Let your eye doctor know of side effects.

    Questions to Ask

    Self-Care / Prevention

    *  Don’t smoke. If you smoke, quit.

    *  Do not take any medicine, including over-the-counter ones, without first checking with your doctor or pharmacist. Most cold medications and sleeping pills, for example, can cause the pupil in the eye to dilate. This can lead to increased eye pressure.

    *  If prescribed eye drops for glaucoma, use them as directed.

    *  Ask your eye doctor about low vision services and devices.

    *  Try not to get upset and fatigued. These can increase pressure in the eye.

  • Simple Steps To Save Your Sight

    WELL-BEING

    Image of older male getting eyes checked by a doctor.

    Age-related macular degeneration (AMD) is the number one cause of blindness in older adults. AMD damages central vision, which means things like reading, driving and seeing faces are limited or impossible. There is no cure for AMD, but there are procedures and steps you can take to help save vision. Lower your risk of getting AMD with these tips:

    *Don’t smoke.Studies show that smoking increases the risk of AMD. Smokers are twice as likely to get AMD as nonsmokers. If you do smoke, take steps to quit.

    *Know your family history.People with a close relative who has AMD have a 50 percent chance of getting AMD. Detecting AMD early means you could save your vision.

    *Eat a healthy diet.People who eat omega-3 fatty acids, found in fatty fish, are less likely to get AMD. Also, focus on eating leafy greens such as spinach, kale and leafy lettuce. Eat plenty of whole fruits (not fruit juice).

    *Limit unhealthy fats and cholesterol.Eating a lot of saturated fat and cholesterol raises the risk of getting AMD. Avoid processed (packaged) foods with unhealthy saturated and trans fats.

    *Be active.Exercise may keep your eyes healthy. Exercising at least three times per week can reduce your risk of getting AMD.

    *See your eye doctor regularly.An eye doctor can catch AMD early with an eye exam. Find out how often you should have your eyes checked.

    *Protect your eyes from the sun.Always wear sunglasses that have 100 percent UV protection when you are outside. For additional coverage, wear a wide-brimmed hat.

    *Get regular checkups from your doctor.Keeping cholesterol, blood sugar and blood pressure under control also helps maintain healthy eyes.

    *Your vision is too important to leave to chance.A healthy lifestyle and good medical care can help you avoid AMD or catch it early, before it damages your sight.

  • Guard Against Macular Degeneration

    Mature Health: Over Age 50

    Image of mature women receiving an eye exam.

    Macular degeneration is the leading cause of central vision loss for those over 55 years of age. The central part of the retina (the macula) deteriorates, leading to loss of “straight ahead” vision. One or both eyes can be affected. If you are 50 years of age or older, ask your eye doctor to check for macular degeneration at routine vision exams. Ask, too, for a simple home screening device that lets you check for signs of macular degeneration on your own.

    To reduce the risk for macular degeneration:

    *  Keep your blood pressure at a normal level.

    *  Maintain a healthy weight.

    *  Don’t smoke. If you smoke, quit.

    *  Protect your eyes from the sun’s harmful ultraviolet rays. Wear sunglasses with UV block. Wear a wide-brimmed hat.

    *  Talk to your doctor about taking a high dose vitamin and mineral supplement to reduce the risk of advanced age-related macular degeneration.

  • The Importance Of Proper Eye Care

    SELF-CARE CORNER

    Image of older women getting her eyes check by an eye doctor.

    Many people don’t think about their eyes until they start to hurt or develop a problem. But even if your eyes feel fine, they need proper care to keep them healthy. Follow the advice of the National Eye Institute:

    Get regular eye exams.

    Your doctor can recommend a schedule for you, depending on your age and other health factors. Many common eye diseases, such as glaucoma, diabetic eye disease and age-related macular degeneration, don’t have obvious symptoms. An eye exam can find these problems early, when they’re most treatable.

    Eat a healthy diet.

    Your eyes benefit from a diet rich in fruits, vegetables and omega-3 fatty acids. Talk with your doctor about the right diet for you.

    Keep them shaded.

    Wear sunglasses that have at least 99 percent UVA and UVB protection when you’re outside.

    Don’t smoke.

    Smoking hurts your health in many ways, including your sight. It increases your risk of eye problems that can lead to blindness. It’s never too late to quit. For free resources to help you quit, visitsmokefree.gov.

    Protect your eyes.

    Cover your face and eyes with goggles or a full-face mask when playing sports or doing work. Wear safety goggles when working with power tools and sharp objects. Follow your employer’s guidelines for wearing eye protection. Encourage your coworkers to do the same.

    Know your family history.

    If there are eye problems in your family, tell your doctor.

  • Eye Irritations & Injuries

    Eye Conditions

    As you age, your eyes can get irritated more easily because they make less tears. Poorer vision increases the risk for eye injuries.

    Signs & Symptoms

    You feel burning, dryness, itching, and/or pain and swelling in one or both eyes.

    Causes

    For Eye Irritation:

    Causes include particles in the eye; too much sun exposure, low humidity; strong wind; and scratches from contact lenses. Other causes are allergies, infections, and conditions that make your eyes dry.

    For Eye Injuries:

    Causes include a physical blow to the eye; harsh chemicals; and a foreign body that is stuck in the eye.

    Mild eye irritations and injuries can be treated with self-care. More serious problems need medical care.

    Treatment

    *  Wear safety glasses for activities that expose your eyes to sawdust, etc.

    *  When using harsh chemicals, wear rubber gloves and protective glasses. Don’t rub your eyes if you’ve touched harsh chemicals. Turn your head away from chemical vapors.

    *  To help prevent dry eyes, use a humidifier and limit exposure to smoke, dust, and wind. Avoid alcohol.

    *  Use artificial tear drops with your doctor’s okay.

    *  Don’t stare directly at the sun, especially during a solar eclipse.

    *  Wear sunglasses that block UV rays.

    *  Don’t use eye makeup when an allergy or chemical irritant bothers your eye(s).

    Self-Care / Prevention

    To Ease the Discomfort of Dry Eyes:

    With your doctor’s okay, use over-the-counter artificial tear drops, such as Ocu-Lube. Read the label. Refrigerate the solution, if needed. Wash your hands before using.

    To Treat an Insect Bite Without a Severe Allergic Reaction:

    *  Wash the eye(s) with warm water.

    *  Take an antihistamine if okay with your doctor.

    To Remove a Foreign Particle On the White of the Eye or Inside the Eyelids:

    *  Do not remove an object imbedded in the eye, a metal chip, or a foreign body over the colored part of the eye. (See “First Aid for Foreign Body Sticking Into the Eye” on this page.)

    *  Wash your hands.

    *  If the foreign object is under the upper lid, have the person look down and pull the upper lid away from the eyeball by gently grabbing the eyelashes. Press a cotton-tipped swab down on the skin surface of the upper eyelid and pull it up and toward the brow. The upper lid will invert. Touch and remove the debris with the tip of the tissue.

    *  Twist a piece of tissue, moisten the tip with tap water (not saliva) and gently try to touch the speck with the tip. Carefully pass the tissue over the speck, which should cling to the tip.

    *  Do not rub the eye or use tweezers or anything sharp to remove a foreign object.

    *  Gently wash the eye with cool water.

    To Treat a Bruise from a Minor Injury that Surrounds the Eye but Does Not Damage the Eye Itself:

    *  Put a cold compress over the injured area right away. Keep doing this for 15 minutes, every hour, for 48 hours.

    *  Take an over-the-counter medicine

    *  After 48 hours, put a warm compress over the injured area.

    *  Seek medical attention if these measures do not help.

    First Aid for Foreign Body Sticking Into the Eye Before Immediate Care:

    *  Do not remove the object.

    *  Don’t press on, touch, or rub the eye.

    *  Cover the injured eye with a paper cup or other clean object that will not touch the eye or the foreign object. Hold the paper cup in place with tape without putting pressure on the eye or the foreign object.

    *  Gently cover the uninjured eye with a clean bandage and tape, too, to keep the injured eye still.

    First Aid for Harmful Chemicals in the Eye(s) Before Immediate Care:

    *  Flush the eye(s) with water immediately!

    *  Hold the injured eye open with your thumb and forefinger.

    *  At the faucet or with a pitcher or other clean container, flush the eye with a lot of water. Start at the inside corner and pour downward to the outside corner. This lets the water drain away from the body and keeps it from getting in the other eye.

    *  Keep pouring the water for 10 to 30 or more minutes. Flush the eye with water until you get medical help.

    *  If both eyes are injured, pour water over both eyes at the same time or quickly alternate the above procedure from one eye to another. Or, place the victim’s face in a sink or container filled with water. Tell the victim to move his or her eyelids up and down and remove the face from the water at intervals in order to breathe. Use this method on yourself if you are the victim and are alone.

    *  Loosely bandage the eye with sterile cloth and tape. Don’t touch the eye.

    When to Seek Medical Care

    Contact Doctor When:

    You have any of these problems:

    *  Eye pain with eye irritation

    *  An eye that is red and/or swollen

    *  Yellow-green pus is under the eyelid or drains from the eye.

    Get Immediate Care When:

    *  Harmful chemicals have gotten into the eye(s). {Note: Before you get immediate care, give “First Aid for Harmful Chemicals in the Eye(s) Before Immediate Care” on this page.}

    *  A foreign body sticks into the eye. {Note: See “First Aid for Foreign Body Sticking Into the Eye Before Immediate Care” on this page.}

    *  A cut to the eye or eyelid occurs.

    *  Any of these problems occurs with a blow to the eye or other eye injury:

    – Loss of vision

    – Blurred or double vision

    – Blood in the pupil

  • Under Pressure: What To Know About Glaucoma

    MEDICAL NEWS

    Image of eldery women getting her eyes checked.

    Glaucoma is a leading cause of blindness for people over 60, so it’s important to know what you can do about it.

    Glaucoma happens when too much fluid builds up in the eye. This extra fluid causes pressure that damages the optic nerve. This damage cannot be undone once it happens. It can lead to loss of all or part of your vision. But, glaucoma can be managed and the damage to vision can be decreased with proper medical care.

    People at highest risk for glaucoma

    Anyone can get glaucoma. But certain groups of people may be more likely to get it, including:

    *  People with a family history of glaucoma

    *  African Americans over age 40

    *  Anyone over age 60, but Mexican Americans are especially at risk

    *  People who have high eye pressure, thin corneas or optic nerve problems

    *  People with high blood pressure that’s not well controlled

    Signs and symptoms

    Glaucoma often doesn’t have early signs and symptoms until damage has already been done. That’s why getting regular eye exams is so important. For many people, the first sign of glaucoma is loss of their peripheral (side) vision.

    Don’t assume you don’t have glaucoma because your eyes “feel fine.” Many people develop glaucoma without any symptoms.

    Illustration of eye with excessive pressure which can lead to glaucoma.

    What can you do about glaucoma?

    Glaucoma has no cure, but there are things you can do to slow it down and save your vision:

    *  If you have glaucoma, take your medicines every day. Ask your eye doctor how often you need to be seen, and stick to your appointments.

    *  Get a complete eye exam at least every 2 years or as often as recommended. This includes a dilated eye exam.

    *  Even if you don’t have glaucoma, ask your eye doctor about your risk. This includes telling your doctor about any family history of glaucoma.

    People with certain risk factors for glaucoma may be given special eye drops. These drops can lower the risk of getting glaucoma but they must be used regularly to be effective.

    If you are diagnosed with glaucoma, you and your doctor will discuss what treatment is best for you. It may depend on what type of glaucoma you have and how severe it is. Treatments may include:

    *  Eye drops that lower pressure in the eye

    *  Surgery done with a laser that helps the eye drain fluid better

    *  Traditional surgery that may include placing a new drainage tube in the eye

    Save your sight – see your eye doctor to get checked for glaucoma!
