Work Concussions are a complex type of brain injury that is not visible on routine scans of the brain, yet are detectable when important aspects of brain function are measured. King-Devick Test (K-D Test) is a two-minute test that you can utilize to check for an employee injury. The King Devick test is a series of cards which use vision to screen for a possible injury. The King Devick test was designed for athletes to detect changes which can indicate the presence of concussion injury. But i believe could be an excellent triage tool.

Visual Fatigue

As an employer have you observed employees who now are making simple mistakes, seen their productivity levels reduced, or struggling with concentration? Look into their eyes.

Recently in the news we’ve read about air traffic controllers falling asleep while on the job. OSHA has alerted employers as to the dangers for employees that work nontraditional work hours. I personally have encountered employees whose symptoms suggest fatigue. So I thought I’d share with you how your eyes are affected by fatigue and behavior that may indicate visual fatigue.

The human eye has muscles which control your eyes focusing. And like any muscle; these muscles get fatigued. The human eye requires a minimum of six hours sleep in order to function properly. Less than six hours of sleep and those muscles which control focusing are strained and react more slowly resulting in reduced visual performance for activities such as reading driving, and computer work. Less than six hours and the normal blink rate of twenty times per minute for the eye’s proper lubrication is severely reduced. Dryness of the eye’s cornea can reduce visual accuracy and interfere with healthy contact lens wear. When you are fatigued you may notice:

· Difficulty and slowness in maintaining clear sharp vision of reading materials and computer screens

· When you are walking and driving you’ll tend to focus only straight ahead disregarding peripheral vision — as though you have tunnel vision

· Some people report dizziness and not being able to tolerate looking at fast moving objects

· You may experience floaters and flashes of light

· You’ll find it uncomfortable to be in brightly lit rooms and outdoors in the bright sunshine. Night time driving will be difficult due to the discomfort from oncoming headlights

· Your eyes will definitely feel dry or burn, itch, or maybe feel gritty. The eyes may start to tear

· You may begin to feel your upper or lower eyelid twitching

Whether you drive a vehicle, operate a machine, or use a computer you depend on your eyes for your individual performance. Sleep is important for many health reasons including visual accuracy. For your safety and that of others let’s make sure we get the rest our bodies truly need.

Glaucoma: The "sneak thief of sight" When the fluid pressure inside the eyes rises because of slowed fluid drainage from the eye it may damage the optic nerve and other parts of the eye, causing the loss of vision or even blindness. Unfortunately there are no symptoms in the early stage of glaucoma. By the time the patient notices vision loss, glaucoma can only be halted, not reversed.

In the United States, African Americans have the highest risk for glaucoma. But until recently the risk for Asian Americans had not been quantified. Researchers at Kellogg Eye Center, University of Michigan presented their findings after reviewing the records of 2,259,061 eye care recipients aged 40 and over who were enrolled in a managed care network in 2001-2007. U.S. Latinos and Asian Americans have roughly the same risk for open angle glaucoma while both have a little more than half the risk of African Americans. Those of Japanese origin had a 9.49 percent prevalence of open angle glaucoma. Those of Indian and Pakistani ancestry had levels at 7.78 and 7.70 percent..

Narrow open angle glaucoma (NAG): Asian Americans have the highest risk for with U.S. Latinos coming in second.

Normal-tension glaucoma rates are fairly low for all groups, but Asian Americans have the highest risk, at 0.73 percent, twice the prevalence for white Americans. For NAG, Vietnamese and Chinese Americans had the highest prevalence (4.08 and 3.74 percent). For NTG, Japanese Americans had the most risk, at 1.99 percent. In normal-tension glaucoma, the optic nerve and vision are damaged even though the eye pressure registers as normal.

Diabetes is the leading cause of blindness. Currently 401 million Americans battle this disease. Finding and treating the disease in its earliest stage is by far the best way to manage its affect on the body. too often one's vision many not be affected until diabetes is in advanced stages. For this reason many doctors recommend annual eye health examinations. Especially if diabetes is present in your parents and family's health history. Here are 6 symptoms that indicate you should contact your eye doctor:

Sudden, rapid occurrence of: blurry vision and/or double vision

Spots or floaters in your vision

Pressure in the eye

Vision doesn't seem as clear & sharp as usual

Reading becomes difficult

Researchers have discovered that as little as a two-hour exposure to light from hand held reading devices (self-luminous electronic displays) can suppress melatonin by about 22 percent. Researcher Mariana Figueiro, an associate professor at Rensselaer Polytechnic Institute and the director of the Light and Health Program, indicates stimulating the human circadian system to this level may affect sleep in those using the devices prior to bedtime. Figueiro recommended dimming these devices at night as much as possible in order to minimize melatonin suppression, and limiting the amount of time spent using these devices prior to bedtime

The U.S. Food and Drug Administration (FDA) is warning the public that accidental ingestion by children of over-the-counter (OTC) eye drops used to relieve redness and nasal decongestant sprays can result in serious harm These products are sold under various brand names, such as Visine.

analysis of Scandinavians ( who drink more coffee than any other nation) showed that, compared to abstainers, participants who drank three cups or more of caffeinated coffee daily were at an increased risk of developing exfoliation glaucoma or glaucoma suspect. The researchers did not find associations with consumption of other caffeinated products, such as soda, tea, chocolate or decaffeinated coffee. The results also showed that women with a family history of glaucoma were at an increased risk. This is the first study to evaluate the association between caffeinated coffee and exfoliation glaucoma and would require confirmation of these results in other populations to lend more credence to the possibility that caffeinated coffee might be a modifiable risk factor for glaucoma,

Prescription corrective surgeries have been used since the mid 1970s becoming very common place with the introduction of lasers in the mid 1990s. Those individuals who've undergone the procedures will develop cataracts just as everyone else because corrective surgeries change the outside shape of the eye; not the lens inside your eye. But it is important that individuals request a copy of their records from the prescription corrective surgery. Unless the surgeon performing the cataract surgery is the same who preformed the corrective procedure; he will require information on the shape of the eye and previous Rx. Without this information; the cataract surgeon is lacking vital information.

Children who spend more time outdoors may be less likely to suffer from nearsightedness. Researchers who pooled the results of eight previously published studies involving more than 10,000 youngsters found that each additional hour spent outdoors during the week decreased the risk of developing nearsightedness (myopia) by 2%. This translates to about a 13% reduced chance of developing nearsightedness per extra hour per day of outside physical activity. Nearsightedness is much more common in the U.S. and other countries than 40 years ago, according to the American Academy of Ophthalmology. Another study showed about 4% of preschoolers had nearsightedness. In some Asian countries, more than 80% of the population is nearsighted.

Ocular Vitamins scientific research continues to show that Vitamin supplements and proper eating habits can help reduce your risk of cataracts, macular degeneration, glaucoma and diabetic retinopathy. And by including generous servings of fresh fruits and vegetables you can improve your body’s ability to fight disease. But be careful for an overabundance of anything, even a good thing is not the best way to go. Megadoses of ascorbic acid, zinc and copper may even have adverse effects on your health. Moderation is the key to success

Only 12% of American adults consume the 3 -5 servings of fresh fruits and vegetables daily says the American Journal of Public Health. Even this recommended daily allowance (RDAs) of vitamins and minerals may not be enough for everyone. Of special concern are RDA levels for seniors who stay indoors and don’t vary their diets, individuals who have chronic medical conditions or those required to take many different medications. Mounting evidence suggests a poor diet can lead to disease….Here are my recommendations for you to discuss with your doctor to prevent eye disease:

Cataracts: A daily multivitamin reduces the risk of cataracts by 25%. Vitamins C and E, along with leafy vegetables like spinach, also reduces your risk of developing cataracts.

Macular degeneration: Lutein, a plant pigment, is found in leafy vegetables such as spinach. Reduced levels of Lutein in the eye have been reported in patients with macular degeneration. Bausch & Lomb has developed a vitamin supplement Ocuvite for patients with macular degeneration.

Glaucoma: A brisk walk regimen, vitamin B 12 and magnesium may help reduce pressure inside the eye.

Diabetic retinopathy: Magnesium and vitamin C may slow the onset of this Disease. Blood sugar control and routine exams are important in preventing diabetic retinopathy.

Vitamin Robbers I should note other agents can deprive your body of needed vitamins and nutrients. Alcohol, tobacco, and cholesterol lowering drugs interfere with the body’s ability to store vitamins. Steroids are known to lower your stores of calcium . A side affect of aspirin is the depletion of the body’s levels of iron and folic acid. Antacids and diuretics also take their toll. Discuss with your doctor or pharmacist options to maintain proper levels of vitamins and minerals.

A healthy diet and vitamins won’t protect you from every disease. They are a very critical part of an overall eye care program which should include exercising, not smoking, protecting your eyes from UV and having regular exams. For more information on vitamins be sure to visit me when I'm next at your facility for a complimentary sample. To print a money saving coupon, visit the web site www.bausch.com.

Computer ergonomics: The science of computer vision

When you read just one word, your left and right eye teamed together point to the first letter of the word, identifying each of the letters as the eyes move from left to right across the word; transmitting that information back to the brain as it comprehends the word. And all of this takes place in about a tenth of a second. It's easy for your eyes to read with your glasses text which has clearly defined characters such as on a printed page. But when you read a word on a computer monitor you're actually viewing a projection of a letter made up of round dots called pixels. That's why pixel concentration, text colors, font type and size, and flicker rates are critical computer vision issues.

The human eye as it ages into the thirties and forties loses the ability to effectively accommodate as eye teaming begins a downward trend. While viewing the image on a computer monitor the normal blink rate of 20 times per minute is reduced to levels as low as 4 blinks. Dryness of the eye continues to increase as we all get even older. In other words you're having a difficult time keeping your eyes focused and your vision clear and sharp.

As we age the lens inside your eye becomes less clear. The muscles inside your eye which flex the lens become less capable to control the lens focusing; i.e. your arms don't seem long enough. Progressive bifocals which have been prescribed to address visual issues for the computer user reach a level where even this lens cannot provide clear sharp vision for distance, reading, and the computer. This usually happens as the reading power of the progressive bifocal increases over +2.00. The physics of the progressive in higher reading powers causes the mid range and near portions to "shrink". Thus these smaller zones force the progressive bifocal wearer to tip their head upward placing stress on the neck, shoulders, and back. If you have trouble seeing the screen you'll adjust your head and body so you can which then adversely affects your proper ergonomic positioning. I cannot stress the importance your eye doctor understand fully your visual demands at home and at work. A prescription for just the computer is the alternative over trying to make one pair of lenses work at three different distances. I discuss these issues and solutions in my programs Combating Visual Fatigue and Avoiding Computer Vision Syndrome.

Eye Health = Eye Safety.... an often overlooked essential part of eyeglasses for some prescriptions is adding an anti-reflective coating. Just an expensive add on you say? What if I explained that with an anti reflective coating on your lenses; it is the difference between seeing 20/20 versus 20/30. You wouldn't have to live day after day with the eye fatigue associated with computers, whiteboards, and lighting. And I could demonstrate that your eyes recover a full 5 seconds faster from headlight glare with anti reflective coated lenses. That means your improved reaction time can help you stop your vehicle 20+ feet sooner. Take a minute to examine our display to learn if you would benefit from an anti-reflective coating when I next visit your office

Sudden, rapid occurrence of: blurry vision and/or double vision

Spots or floaters in your vision

Pressure in the eye

Vision doesn't seem as clear & sharp as usual

Reading becomes difficult

Back to school.... While we are still enjoying our favorite summer activities the calendar tells us the beginning of schools is just around the corner. Be sure to add to your Back to School checklist a visit for your child to see the eye doctor. Good vision is fundamental to children’s reading, learning, and comprehension . Good vision is essential for children to realize their true academic performance. Often children with vision problems don’t know the world is different from the way the now see it.

Remember vision is much more than 20/20. This is only a measurement of acuity: how clear and sharp is a 1 & 7/8 inch letter projected on a wall at a distance of twenty feet. A thorough vision examination analyzes a child’s eye teaming (both eyes working together) focusing, field of vision, comprehension, color vision and acuity both near (reading) and far (distance).

As parents; please familiarize yourself with these warning signs of a visual problem. Observe your child’s behavior and ask the teacher if any of these symptoms are displayed in the classroom. While reading:

Squinting, closing one eye, rubbing of eyes

Complains of headaches, dizziness, nausea, or double vision

Turns or tilts head to one side

Loses place or uses fingers to point to each word

Reverses letters

Brings reading materials very close to the eyes (normal reading distance 16 -18 in)

Omits words or skips lines

Unable to align numbers horizontally or vertically

Do you observe:

Gets close to television or chalkboard

Dislike or avoidance of reading

Short attention span

Trouble seeing the computer screen

Is that sweat in your eyes? Sure enough the calendar says it's sweat season. As temperatures increase so does the frequency in which perspiration affects your employees' eyes. Besides stinging; perspiration in the eyes causes dryness, blurred vision, and a reduction in clear sharp eyesight. And it is important to remember that workers who work inside and outdoors are both affected. When you compile your sweat management program please consider my suggestions. Stock ocular lubricants in your first aid room to refresh the eyes. Familiarize yourself with this condition in my dry eyes article. Eye injuries from wiping sweat are caused by inadvertently placing dust, debris, or chemicals into the eye. Set up safe zones where safety glasses can be removed for sweat removal/PPE cleaning without increasing the risk of an injury. Consider utilizing the two safety frame styles which include a sweat brow protector. And If you wish to provide employees with Dry Eye orientations; please contact me directly to schedule our Dry Eye wellness program

Outside worker protection

When workers work outside they encounter conditions which we must prepare for:

Problem 1: A gust of wind blows debris into the eye.

Treatment: Resist the urge to rub the eye as this could actually scratch the eye. Immediately try to flush the eye by adding a lubricant and point your eyes downward and begin to rapidly blink. These actions should help the eye flush out the irritant. If the eye still feels uncomfortable seek medical attention. If you would like a lubricant sample; please let me know

Prevention: use the appropriate safety glasses with the largest possible protection area for the eye orbit and side shields

Problem 2: While working around trees or shrubs a branch knocks off your glasses scratching your face and eye.

Treatment: Rinse the eye as quickly as possible with sterile saline. Loosely bandage shut with tape and a sterile folded gauze. Seek medical attention.

Prevention: use safety glasses that incorporate a headband device minimizes possibility of the eyewear being knocked off

Problem 3: that evening or possibly the next day after working outside the eye turns red, itchy, and starts to water (may be sensitive to light).

Treatment: the eye is experiencing an infection and requires medical attention.

Prevention: wear the appropriate safety eyewear and clean your safety eyewear after outside activities have concluded, clean hands with antibacterial soap

Be sure to check your first aid station for lubrication drops and eye patches. If the affected employee uses contact lenses please refer to my recommendations for first responders posted in my article: Contact lenses worn in an industrial environment

Unfortunately scratches on prescription safety lenses are not totally avoidable. The best way to avoid scratches is to prevent them form occurring in the first place. Simple preventive steps like storing your glasses in a protective case when not worn, wet the lens before cleaning, dry the lens with a clean cloth (or an approved tissue from a lens cleaning station) and employing a supplemental face shield/visor when necessary. The problem with scratches is they are not only bothersome; but can pose a hazard to the employee.

Scratches problems: Protection and Performance ... Scratches on lenses pose two problems for the safety of the employee. The first is the most obvious. When the lens surface is scratched; its ability to withstand an impact and not shattering is compromised. The second problem is scratches reduce the clarity of the prescription lenses which can reduce the performance of the employee. And when people have a trouble seeing through their glasses; they tend to bend, lean, and tilt their heads which affect their overall musculoskeletal health.

Scratch patterns

O If when examining the lens scratches you observe the scratches tend to go in a circular fashion in the center of the lens; the lens was probably not wet when it was cleaned. The proper method to clean lenses should be reviewed with the employee.

- `~ If your lens examination reveals short scratches indiscriminately placed on the surface you should consider an optional protective device like a flip up face shield. The lens is being bombarded with flying debris.

If you observe scratches longer than 3mm; there is a high probability the lens was dropped.

Best way to clean lenses ... When cleaning prescription lenses the first step is to wet the lens surface. Water, a lens cleaning solution, or soap and water will remove dirt and debris quite effectively from the lens surface. Most scratches can be traced to either wiping the lens dry or using a cloth (or shirt tail) that contains abrasive materials. Avoid applying household cleaning products like window cleaners, acetone, and paint remover as they contain chemicals which fog the lens and damage the coatings on the lens.

Scratches on lenses can be polished out …. NO. Prescription ophthalmic lenses are required to maintain a 2mm thickness for high impact polycarbonate lenses and 3mm thickness for glass, CR39, and high index materials. Polishing results in a decreased thickness yielding a higher risk of shattering. In addition, the lens front surface is a custom molded on multimodal lenses (bifocals) and can not be resurfaced. Polishing is usually reserved for large telescopic lenses or special optical systems.

My recommendations for replacing lenses: If you hold the lens up to a light and are unable to see through the lens due to scratches: replace it! If any part of the lens has chipped or the surface is pitted: replace it! If cracks are visible in the lens: replace it!

After a prescription safety lens is scratched; its protective capacity is compromised. Avoiding scratches is the best prevention. You can use the Risk Assessment on our website (www.wecare4eyes.com/hazard assessment.htm) to determine those employees at a higher risk of incurring scratches. When in doubt the lens which is scratched should be replaced. An option to consider for those employees whose work exposes lenses to more scratches is our scratch warranty. The scratch warranty for high impact polycarbonate and CR39 lenses provides for the replacement of the lenses (single vision or bifocal) at no charge once in a one year period. The small cost for the warranty protection is minimal compared to replacing bifocal lenses. For more information regarding this warranty option; please contact our office at 708-686-5266

Toxic keratoconjunctivitis When caustic chemicals or solvents splash into the eye; immediate effective action is of the utmost importance to avoid permanent scarring of the ocular surface. The most commonly accepted treatment option is rinsing the eyes using an eyewash station. But what if you can’t get to the station or one is not available? Rinsing at copious levels with sterile saline from your first aid station is an effective method. In a worse case scenario; run tap water into cupped hands and repeatedly submerge the affected eye into the water. Be sure to remove any contact lenses; rigid or soflens. You can’t assume the rinsing action will flush the contact lenses out of the eye.The eye's natural response to the chemical splash may force the contacts under the upper eyelid or into the corner. If allowed to remain in the eye; the contact lenses which have absorbed the chemical will continue to irritate the ocular surface. ( I recommend that your office maintain a file of employees using contacts on the job and their employee ID contain an easily visible sticker) Once the eye has been successfully irrigated don’t forget to use natural tears as the eye’s normal tear volume will have been comprised. Non preserved lubricants eliminate the possibility of a preservative further complicating the eye’s condition. Applying a cold compress will help reduce the pain. The employee should be be examined by an eye doctor as soon as possible.

Vision Misconceptions

Squinting: Even if mom might have shared this one; squinting will not make your vision worse. But squinting is a possible symptom of the eyes having trouble focusing.

Reading with a flashlight: will not make your eyes worse but reading in poor light surely puts a strain on the visual system.

Sitting too close to the television: mom might have warned you about this but scientifically speaking; sitting too close won't hurt your eyes. But many times people (especially children) sit close to the television for they have trouble seeing the screen comfortably.

Eating carrots is good for your eyes: actually eating dark green vegetables like spinach and broccoli is better for they contain high amounts of lutein which has been proven to protect the eye from disease. Carrots are good for your diet; but they won't make you see like a hawk.

Wearing your eyeglasses makes your eye dependent on them: vision should be an automatic function. You shouldn't have to manually make your eyes focus on an object in order to see it. Prescription lenses allow your eyes to function normally. You can't get "hooked" on your eyeglasses and they don't make your vision worse.

Safe Driving Recommendations

Since 1980 the number of vehicles on the roadways have increased 37%. For the average driver the total number of miles traveled has increased a whopping 80%. And as we all know; our daily commute to and from work has grown too long. The math is simple: more time on the road equals an increased risk of a driving mishap.

I’m sure we all agree two necessities for safe driving are clear sharp vision and up to date prescription lenses. Here are three of my professional recommendations to help you drive as safely as possible.

Have your visual health checked regularly. A recent study in the United Kingdom ( a 1000 person study) discovered 35% failed a basic eye test. 65% of those who Failed- Drove! Up to date prescription lenses provides you optimum vision. For daytime driving; it’s best not to drive one hand shading your eyes from the sun And the other hand holding a cell phone. The right lenses for sun protection Eliminates squinting and improves your focusing. Sunglasses will reduce troublesome reflections off pavement. No matter the road conditions: hot & dry, wet from rain, or snow covered. For specific suggestions, please refer to our earlier report “ Ultraviolet light: The invisible threat”.

My last recommendation concerns your prescription lenses and night time driving conditions. As you drive; every 2 miles the average driver is engaged in 400 visual observations and up to 40 decisions. Night time driving is complicated by 4 conditions which reduce your safety factor.

Oncoming headlights cause distractions from glare and reflections

Annoying halos around lights reduce visual contrast

Diminished visual acuity results in slower reaction times

Eye strain and eye fatigue combined limit the number of comfortable hours for driving

However you can almost eliminate the affect of these night time conditions with a simple lens coating. By adding an anti-reflective coating to your prescription lenses will reduce: Glare & reflections - Halo effect - Time for eyes to recover - Eye fatigue

More worker fatalities are caused by vehicle crashes in the U.S. than any other incident category. Hopefully my recommendations for safe driving: annual check -ups, proper sunglass tints, anti-reflective coatings; will decrease the likelihood you’ll suffer a driving mishap.

Ultraviolet light: The invisible threat

Ultraviolet light is known to damage the retina inside your eye. What actually occurs is an intense shedding of the photo receptors in the delicate lining at the back of your eye.

Young children are more susceptible to the harmful affects of UV because the lens in their eyes are still developing. Individuals who have undergone cataract surgery should incorporate more ultraviolet protection. Because once their cataract is removed; the eyes natural protection against UV affects is eliminated. People with light colored eyes (blue, gray, green) are more sensitive to ultraviolet light’s affects. And people who use certain medications increase their sensitivity to ultraviolet light. Common examples are certain allergy medications, oral contraceptives, and acne remedies.

Polycarbonate, high index, and CR-39 plastic lenses for your eyeglasses with Transitions provide at minimum 96% protection against UVA wavelengths. UVA is the wavelength normally associated with skin tanning and sunburn. Many brands of contact lenses in both rigid and soflens materials now incorporate UV protection. Among the brands you should ask your doctor about are Boston RXD and Boston ES, Precision UV, Acuvue disposables and some Ciba brands.

How can you protect your eyes from Ultraviolet light damage?

* Wearing a hat (with front covering brim) blocks up to 50% of the harmful UV

* Be aware the peak hours of ultraviolet light is between 10 a.m. and 2 p.m.

* Utilize Polaroid or mirror coated lenses for higher protection levels

* Sunglass lens tints should be uniform from top to bottom and side to side

* Can you see your eyes in the sunglass lenses? If yes, not enough density for protection

* For maximum protection from ultraviolet light, your sunglass lenses should have one of the following colors: gray, green, brown

How can I be sure my store bought sunglasses are not defective?

The sunglasses you buy off the rack at the local drug store or gas station many times contain warped lenses. And there is no uniform labeling on ultraviolet light. So you should check your store bought sunglasses by first holding the sunglasses at arm’s length. Look through the lenses at a straight line in the distance such as an edge of a door. Slowly move the sunglass lenses across the straight line. If that straight line distorts, sways, or curves- the lenses have imperfections and should not be worn.

We invite your inquiries by phone (708-686-5266) or email at duane@wecare4eyes.com. Of course we regularly visit your offices for safety glasses and look forward to personally helping you with any questions regarding your vision.
