HOW TO COPE AS A

P
RESBYOP
E


"My arms are not long enough anymore."
It may be time for you to consider reading glasses.

The crystalline lens of the eye which has a function somewhat analogous to a zoom lens on a camera begins to harden with age, making the closest point of focus further out from the body, resulting in the symptom of "arm shortening." This is a very gradual process that most people begin to realize between the ages of 37 and 45. It is also a process that reaches an endpoint by age 60 in most individuals, after which the strength of one's reading prescription usually remains stable. By the way, the technical name for this condition is presbyopia (pronounced prez-bee-OH-pee-uh).

Years ago, very few options were available to battle this natural aging process. Before 1785, those who could afford two prescriptions simply bought one for distance vision and one for reading. However, many-including Benjamin Franklin-often found this dreadfully inconvenient, that is, always having to switch back and forth between pairs of spectacles. Consequently, he had his lenses cut in half and half of each kind mounted into the same frame. This bifocal is similar to today's executive bifocal; however the two lenses are now fused.

Additionally there are numerous other options today, including all types of lined bifocals-and thanks to technology-progressive addition lenses that have been dubbed "no-line bifocals." The "no-lines," of course carry the advantage of hiding one's age, while offering an infinite range of focal points. The trick is learning what part of the glasses to look through, depending upon what one wants to see. The top-center portion of the lens should be utilized for distance viewing, and as one looks further down toward the bottom part of the lenses, the reading power increases. It should be noted, however, that a person wearing this type of bifocal must move his or her head toward an object off to one side or another (rather than eyes only) to avoid peripheral lens distortion.

The prospect of wearing contact lens in this age group should not be overlooked. In many instances, they are able to provide sharp, clear vision-including better peripheral vision than with glasses. Lenses are specially designed for your eye size, the curvature of your eye, the tightness and dimensions of your eyelids, the pupil size, the health of your eyes and, of course, to allow you to see clearly both at distance and near.

Unfortunately, technology has not provided us a viable option of laser correction for presbyopic patients except in select cases. These cases involve nearsighted patients who are willing to have one eye corrected for distance vision and one eye corrected for near. However, this method is not foolproof, and glasses or contact lenses may be required after such a procedure in order to realize maximum vision.

The advent of the computer has brought, forth an increase in an entire range of symptoms-from intermittent blurry vision and headaches to stiff necks. Some compare the continual use of a computer throughout the day to holding a pair of ten-pound weights for the same eight hour period. In actuality, it is quite a valid comparison when one considers the strain that data entry, computer programming and word processing can put on the visual system-not to mention the rest of the body. One suggestion to relieve this strain is to look away from the computer for 30 seconds every 30 minutes. Look out the window, down the hall or simply close your eyes. This gives the visual system time to recoup.

A stiff neck is most likely the result of an inherent design flaw in a conventional bifocal. Bifocals are designed for reading written material below eye level. Having to tilt one's head back to accommodate the computer screen and maintain clarity can be a frustrating and even painful process. You can buy a new computer system, hire a masseur or more economical and practical buy a second pair of glasses made specifically for computer use. After all most people own more than one shirt or more than one pair of shoes-why not glasses?

Because our sight is so important to each one of us, preserving this precious gift becomes paramount. Yearly examinations are essential to rule out age related macular degeneration, cataracts, glaucoma, diabetic eye disease and ocular pathology.


DIGITAL RETINAL IMAGING


Over the years, our patients have come to expect state of the art care and services. Our Doctors are committed to providing the very latest in technical innovations to our patients. Many of the procedures available in our office are not available from any other practice in the area. This is one reason that patients have come to relay on us for their eye care needs.

We are pleased to inform you of the addition of an instrument that compliments our comprehensive list of twenty-first century, state-of-the-art equipment. DIGITAL RETINAL IMAGING is a new technology that allows instant viewing of retinal images by the doctor and the patient. This computerized technology aids us by establishing baseline images of the inside of your eyes. We can then compare this image with future images and carefully observe any normal or abnormal changes. We believe this will promote earlier diagnosis of many abnormal vision conditions, some of which can result in permanent vision loss if not caught and treated in a timely manner.

DIGITAL RETINAL IMAGING combines the technology of retinal photography and computerized digital imaging to produce remarkably clear retinal images. We recommend DIGITAL RETINAL IMAGING every year for patients who are at risk of developing eye disease, such as diabetics, patients With high blood pressure those at risk of age related macular degeneration and those with a family history of glaucoma. For those individuals who already show some type of retinal abnormality, retinal imaging is medically necessary and will be performed at the interval deemed appropriate by the doctor.

Medical insurance companies reimburse DIGITAL RETINAL IMAGING only when when there is existing eye disease. All other imaging is non-reimbursable. Our fee for DIGITAL RETINAL IMAGING is $35.00. We are overwhelmed with the results of this procedure and highly recommend DIGITAL RETINAL IMAGING as an optional addition to your examination today. Please indicate your preference below.

Please perform baseline DIGITAL RETINAL IMAGING as an optional additional procedure to my examination.

I do not wish to have baseline DIGITAL RETINAL IMAGING performed.

It is that easy!



Your Vision . . .
Your Job Depends On It!

When you think about the skills and tools you need to do your job, what do you think of. If you work in manufacturing, you operate complicated, high-tech machinery and use years of experience to produce high-quality products. If you're a secretary or receptionist, you probably use the computer, answer the phone and type. If you work in construction, you may prepare cost estimates, read blueprints and use surveying equipment, hammers and nails.

But would you be able to do any of these tasks well without the most important tools of all your eyes and good vision? Probably not.

Your eyes and good vision can be the most important tools in your job and all the other daily activities of your life. But do you, like many people, take them for granted?

Have you noticed more mistakes in your work lately? As the day progresses, do you get more and more fatigued? Do you have frequent headaches or eye strain? If you answered yes to any of these questions, you probably need a thorough vision examination. Often mistakes, fatigue and difficulty with new tasks, are a result of a vision deficiency.

It is important to seek professional optometric care on a regular basis.

When you visit us . . . keep us informed when you take on new tasks, or notice any changes in vision or the way you feel at the end of the day.

We will check a variety of different factors including visual acuity work together as a team, as well as for eye disease and general health. Correcting these conditions may improve your productivity, reduce errors and, of course, increase comfort on the job.

You might need two different prescriptions: one for your regular vision needs, and another for specific job-related tasks such as close inspections of products coming off the assembly line, for long hours spent looking into a VDT screen, or for reading a chart or dial above eye level.

In a thorough exam, we might determine that your prescription for your new tasks is fine. But you might benefit from a simple "extra" such as a lens tint for outdoor work, an anti-reflection coating, or safety lenses for added eye protection or perhaps contact lenses.

No matter where you work... in an Office, in a Factory, on a Construction site and even at Home, good vision will make your work more productive, more comfortable, and more enjoyable. Even if you don't detect any changes in your vision . . . your job depends on it.


Eye exams can reveal a lot about your health

Sometimes a routine eye exam ends up being not so routine after all. Charles Brownlow, O.D., a practicing optometrist for 27 years and executive vice president of the Wisconsin Optometric Association, remembers one such exam a few years ago.

"I'd been seeing this particular patient let's call him 'Joe' - for about 15 years," says Dr. Brownlow, "and one morning he came in for his regular eye exam.

"At first everything seemed strictly routine. Joe's vision hadn't changed in two years, and his eyes looked perfectly normal.

"But when I asked him some questions about his vision, he explained that one eye felt weaker than the other. He told me: 'Doc, things just don't look as bright or as sharp out of that eye!"

"After reviewing his chart and listening to his symptoms, I knew something was wrong and that we had to take action," recalls Dr. Brownlow. "Thankfully, my education and experience paid off that day. Countless other patients have also benefited over the years when visiting an optometrist because they believe they have a routine vision problem, but leave the office with a far different diagnosis."

Dr. Brownlow moved quickly. He referred his patient to a general physician, who sent him to a specialist. The diagnosis: carotid artery disease, in which fatty deposits build up on artery walls where they can trigger fatal blood clots.

"Joe had a major blockage in the carotid artery on one side of his neck," says Dr. Brownlow, and the blockage was cutting down on the blood supply to the brain and eye. "They hurried him into surgery, and he managed to avoid what could have been a life-threatening stroke."

Regular Eye Exams
Are the Key

Most eye exams don't produce such dramatic consequences, but there's no doubt that getting your eyes checked every year or two is a key step in protecting the priceless asset that is your vision.

"Regular eye exams are extremely important, because they can uncover major health problems such as diabetes and high blood pressure," says Dr. Brownlow. "But a periodic eye exam is also necessary to assess the overall health of the eyes, to determine whether or not the patient needs vision correction with lenses or just to reassure you that all is fine."

According to Dr. Brownlow, the typical eye exam lasts about 30 minutes and begins with a case history, in which the doctor reviews the patient's medical background and asks about past vision problems.

After that, the doctor examines both the exterior and interior of the eye, looking for possible damage caused by disease, injury or aging. "With the help of modern instruments, we can look at the iris, then straight through the pupil all the way back to the retina."

Depth perception, peripheral vision, and the clarity and accuracy of vision at various distances also are tested. The doctor will prescribe corrective eyewear where appropriate.


How you can avoid computer vision syndrome

The desktop computer: It's revolutionized the workplace, but in its wake have come new challenges to the eyes and vision system.

Health experts now point to "computer vision syndrome" as a major workplace concern. Millions of people in the United States may suffer from this condition, and the number of cases is on the rise, says Jeffrey Anshel, O.D., a Carlsbad, Calif, Vision Service Plan optometrist who specializes in treating the disorder.

Computer vision syndrome, or CVS, is a catchall term for computer-related eye fatigue, blurred vision, headaches and back or neck aches.

"The human eye wasn’t really designed to stare into a cathode ray tube for eight hours at a stretch," says Dr. Anshel, who advises employers on ways to combat CVS. "In many cases, the quality of the image on the screen is poor, which can cause enormous strain on the eyes although it doesn't damage them.

"Many optometrists feel that people who work with computers should get their eyes checked regularly," says Dr. Anshel.

 

Fight CVS with Three Bs and the 20-20-20 Rule

Computer users can fend off CVS by taking short breaks and briefly refocusing their eyes, says Dr. Anshel, O.D.

"I've come up with a strategy that I call "the Three Bs," says Dr. Anshel. "If you're working in front of a computer screen all day long, you need to remember to blink, breathe and break.

"In other words, you should take frequent breaks, during which you blink your eyes repeatedly and take several deep, relaxing breaths while stretching your body.

"It also helps to follow my '20-20-20 Rule' during these breaks," he says. "Every 20 minutes or so, take a 20-second break in which you look carefully at objects that are at least 20 feet away."

"If you follow the Three Bs and the 20-20-20 Rule, you'll reduce your chances of computer-related vision problems," says Dr. Anshel.

Choose Your
Monitor with Care

Want a monitor that will ease the wear and-tear on your overworked eyes? Look for the following:

A high-quality image. "The larger, flat-panel LCDs (Liquid Crystal Displays) are the easiest on the eyes because the imaging is more powerfully focused,' says Jeffrey Anshel, O.D., who treats computer vision syndrome. 'But if you have to use an older model, try to get one that doesn't flicker, and that features a sharp contrast between the field [background] and the images.'

Flexible positioning. Your computer monitor should be positioned at a distance of at least 20 inches from your eyes (about an arm's length). It should be placed so that you look down slightly when you're reading the screen. Position your keyboard directly in front of the monitor to cut down on excessive eye movements as you look from keyboard to screen.

Minimum glare. Some monitors have glare-reducing screens. Others feature hoods or shields that keep light away. Remember to dust the screen frequently -dust buildup reduces image quality.



When Should You Have
Your Child's Eyes Checked?

Ask Wendy Marsh-Tootle, O.D., of the University of Alabama Birmingham (UAB), and she'll tell you it's never too early for an eye examination - especially if you suspect that your child has an eye or vision problem.

"Eye doctors can conduct an eye exam long before a child can talk, so get your baby’s eyes checked early if you suspect an eye or vision problem," says Dr. Marsh-Toode, an associate professor and director of pediatric services for UAB's School of Optometry.

Ideally, all children should have their eyes examined by an eye doctor at least by the time they enter school. In fact, the American Optometric Association suggests that children should have their first regular eye exam at 6 months. Follow-up exams should occur at age 3 and again just prior to starting school. If a problem is found, more frequent care may be necessary.

For young children without obvious signs of an eye or vision problem, Dr. Marsh-Toode says eye doctors rely on pediatricians to screen for some important problems at key ages. "A baby’s visual system is very immature at birth and develops very rapidly, so newborn screenings by the pediatrician are very important," she points out. "For example, rare problems such as cataracts must be treated within the first few weeks of life or normal vision will never develop."

So what's a parent to do? Keep a watchful eye, so to speak, on your child's eyesight from infancy through adolescence.

"After the first few weeks of life, your baby should seem to look at you, " Dr. Marsh-Toode says. "After a few months, he or she should use eyes together more and more. If your baby does not appear to use his or her eyes together normally by the sixth month, get a checkup from an eye doctor."

Once children reach preschool age, it's important to have them checked for "lazy eye," as well as for risk factors including high refractive error or strabismus. Treatment of these conditions before the child enters school is easier on everyone.

Finally, once your child starts school, be sure to have his or her eyes checked for focusing problems and for nearsight. "Both are common conditions that develop during school years, so it's a good idea to get a checkup periodically, particularly if your child is struggling with school work," says Dr. Marsh Tootle. "Most eye problems are easily treated once the problem is diagnosed."

 

Macular degeneration impairs sight of millions

Age-related macular degeneration." It's a tongue-twisting disorder that many Americans have never heard of But that may be changing.

"Macular degeneration is one of the major causes of vision loss among older Americans today," says Christian Serdahl, M.D., medical director of Vision Service Plan. "As our nation grows older, and as we continue to live longer, this disorder will begin to make the headlines more frequently."

Already some 10 million Americans, most in their 60s and 70s, are affected by the condition, which attacks the light-sensitive tissue at the back of the eye and causes gradual and irreversible vision loss.

"Unfortunately, there is no immediate cure on the horizon for most people with macular degeneration. Researchers are now closing in on the cause and once we know that, a cure or preventative treatment will result," says Dr. Serdahl.

"We recommend that anyone already diagnosed with macular degeneration who notices a change in the vision of one or both eyes get their eyes checked right away. Sometimes laser can be applied to the macula to slow the progression of the disease," Dr. Serdahl advises.

"We are frequently asked as eye doctors what role vitamins play in macular degeneration "I Dr. Serdahl notes. "To date there is no definitive evidence that supplementation with zinc or vitamins A or E is of any benefit for patients with the disease. However, if I had macular degeneration, I would take a daily multiple vitamin for general nutritional purposes.

While the condition never causes total blindness, it often impairs the central vision to the point that many patients can no longer read, drive or enjoy television. The good news is that peripheral vision is not affected and most people with macular degeneration continue to lead independent lives. Frequently, a low vision evaluation by a qualified optometrist or ophthalmologist is helpful in allowing people to get the most out of what little vision they may have left.

 

Proper fitting of contacts lenses crucial for comfort, safety

If you haven’t worn or investigated contact lenses since leisure suits were all the rage, be aware that some marvelous advances have been made in lens technology. An array of products is available to correct nearsightedness, farsightedness, astigmatism and other vision problems.

"Right now, eye care patients can easily obtain everything from bifocal contacts to new disposable lenses that you can wear for a week - or even a single day - and then simply discard", says Kenneth N. Schwaderer, 0. D., F. A.A.0., a Vision Service Plan optometrist in Mountain View, Calif.

Because lenses offer so many advantages, it's vital that they be properly fitted and worn, says Dr. Schwaderer.

"Contact lenses are a medical device", he says. "But in recent years, there's been so much commercial hype that they’re often put in the same category as a six-pack of soda.

"That's a mistake. Remember that contact lenses still require a prescription, and they should be fitted and handled with the same care that goes into any other medical prescription," Dr. Schwaderer says. "For that reason, I recommend against ordering original contact lenses by mail-order."

A proper fitting of your new contact lenses will confirm that your vision has been corrected accurately, while also assuring that your eyes will not be damaged by wearing the devices.

"Contact lenses fit over the cornea of the eye, and it's important to protect the health of the cornea with a proper fit. An inadequate fitting could damage the sensitive tissues of the cornea, leading to irritation, infection or even an ulcer in that part of the eye."
