BACK-TO-SCHOOL EYE CARE FOR KIDS: WHAT YOU NEED TO KNOW

View Video
It’s back-to-school time! As your child prepares to start another school year, don’t forget to take care of one of their most important learning tools — their eyes.  Find out how you can help keep their eyes healthy, and why an eye exam is so important.

Be aware of vision problems:

Your kid may be spending more time in front of the screen than usual — and that could put him or her at increased risk for certain vision problems or eye conditions.

  • Nearsightedness: If your child is not already nearsighted, doing a lot of “close work” (using a screen or even in a book) can increase their likelihood of developing this condition. Encourage them to hold books or screens at least 18 inches away.
  • Dry Eye Syndrome: When we stare at a screen all day, our blink rate decreases significantly. The blinking action secretes an oil called meibum (one of the three layers of tear film), which keeps our eyes moist. When we don’t blink as much, our eyes can become overly dry and irritated.
  • Eye Strain and Fatigue: Excessive screen time can also lead to strain, fatigue, blurry vision, itchy eyes, and headaches.

Watch for behavioral changes that may signal vision trouble, for example:

  • Talk to your child about their new classroom or where they’re sitting to gauge whether they’re having issues seeing.
  • Ask them whether their eyes ever feel tired after watching something on a screen.
  • Watch for blinking, squinting and tearing of their eyes.
  • Pay attention to headaches or fatigue.

Help minimize any risk to your child’s eyes by doing the following:

  • Make sure they take frequent screen breaks. Instead of focusing directly on the screen, encourage your child to look around the room every now and then, or take some time to stare out the window (at least 20 seconds is recommended by the American Optometric Association). You can even remind them to blink.
  • Position the monitor or screen so it’s about 25 inches away, and also position it so their gaze is slightly downward.
  • Adjust the room lighting so that the screen isn’t brighter than the surrounding light. If it is, your child’s eyes will have to work harder.
  • Sharpen your child’s vision skills with “traditional” non-screen-based activities, like puzzles, blocks, drawing and painting, and playing catch.

Don’t Forget the Eye Exam

It’s easy for us to forget about our eyes let alone our child’s, but it is very important to get your child’s eyes checked regularly.

It is absolutely critical to ensure healthy eye development and that they have the visual skills necessary for successful learning. No matter where your child will be participating in school this year — don’t skip the trip to the eye doctor.

The American Optometric Association recommends children have an eye exam by the time they reach one year old, at least once between 3 and 5 years old, and once a year after first grade until they graduate. Your eye doctor can recommend the best frequency for your child.

Your child should still receive a comprehensive eye exam, whether or not they have received a vision screening at school or even at their pediatrician’s office.  While vision screenings can indicate some vision trouble, they often only test your child’s ability to see things that are far away, such as a classroom whiteboard.  Also, keep in mind the school screeners usually do not have all the necessary equipment or training to detect many eye health problems in children.

A comprehensive eye examination looks at complete eye health, and includes tests for the following, in addition to an understanding of patient and family health history:

  • Visual acuity
  • Depth perception
  • Color vision
  • Peripheral vision
  • Refractive errors (like nearsightedness, farsightedness and astigmatism)
  • Eye focusing, tracking, teaming and other eye movement abilities

Specialists state that 80% of what your children learn in school is taught visually. Untreated vision troubles can put children at a substantial disadvantage. Be certain to arrange that your child has a complete eye exam before school starts.

 

Tips To Protect Children From Digital Eye Strain

With COVID-19 and a shift to online learning by many schools, children are spending even more time looking at screens. Staring at digital screens for a long period of time can cause hazy, blurred vision and can make eyes burn and feel dry, itchy and irritated. This condition is known as digital eye strain or computer vision syndrome. Other symptoms of digital eye strain can include:

  • Neck and shoulder pain
  • Headaches
  • Fatigue
  • Words moving on the screen (due to underlying eye alignment issues)

What Parents Can Do:

  • Monitor screen time. Find some balance between the digital and real world. Two especially important aspects of this are making sure screens don’t cut into:
    • Sleep. Not getting enough shut-eye leads to tired, sore eyes. Avoid exposure to screens for 1 hour before going to bed. Using devices past bedtime, especially for violent video games or shows, can interfere with sleep.
  • Putting down the device or stepping away from the computer or TV can help avoid eye and vision problems from too much screen time. Children age 6 years and older should be getting at least 60 minutes of physical activity each day. Active play is the best exercise for young children. Outside play can also be a great “workout” for children’s vision—giving them a chance to focus at different distances and getting exposure to natural sunlight.
  • Take frequent breaks. Children frequently get so absorbed in what they’re doing that they don’t notice symptoms of eye strain. Remind them to take breaks. Use the 20/20/20 rule: look away from the screen every 20 minutes, focus on an object at least 20 feet away, for at least 20 seconds. In addition, children should walk away from the screen for at least 10 minutes every hour. A simple timer can help your child remember, and there are even software programs that can help by turning off the screen in regular intervals.

  • Remember to blink. Staring at a computer can cut blinking rates by half and cause dry eyes. Encourage your child to try to blink extra, especially when they take breaks. Your pediatrician or eye doctor may recommend moisturizing eye drops or a room humidifier if your child continues to be bothered by dry eyes.
  • Screen positioning. Make sure the screen on your child’s desktop or laptop computer is slightly below eye level. Looking up at a screen opens eyes wider and dries them out quicker. Some experts suggest positioning device screens based on the 1/2/10 rule: mobile phones ideally at one foot, desktop devices and laptops at two feet, and roughly 10 feet for TV screens (depending on how big the screen is). Adjusting the font size—especially on smaller screens—so it’s twice as big as your child can comfortably read may also help reduce eye fatigue.
  • Spotlight on lighting. To cut down on glare and eye fatigue, consider the level of lighting in a room when using a computer or other screen. Ideally, it should be roughly half what it would be for other activities such as writing on paper or working on crafts. Try to position computers so that light from uncovered windows, lamps and overhead light fixtures aren’t shining directly on screens. Decrease the brightness of the screen to a more comfortable level for viewing. Some optometrists recommend special computer glasses with orange lenses that may also help reduce glare. Children who wear prescription eyeglasses may have an anti-reflective coating added, as well.
  • Get regular vision screenings. If your child is having blurry vision or similar eye problems, he or she may not speak up. That’s why regular vision screenings are important. The American Academy of Ophthalmology recommend children have their eyes checked by a pediatrician at well-child visits beginning at birth. If a problem is found during one of these routine eye exams, your pediatrician may refer you to a pediatric ophthalmologist.

Children, especially younger ones, will likely need help and reminders to use digital screen devices in an eye-friendly way.  If you have any questions about keeping your child’s eyes and vision healthy, talk with your pediatrician.

How to Prevent Eye Strain While Working From Home

Working from home has become the new normal for many Americans during this pandemic.  Most are happy without the commute, although working outside the office and in all sorts of strange places, such as bedrooms, backyards, living rooms, has become common place. We’ve had to learn how to work remotely, which in turn means spending a lot more time using computers and smartphones.

Moving out of properly-lit classrooms and offices – and away from ergonomically correct desks – can have long-term effects on our eyes.  Excessive time at a computer screen under the best conditions can lead to symptoms of eye strain.

Eye Strain Symptoms include:

  • Headaches
  • Blurred vision
  • Uncomfortable dry eyes
  • Neck and shoulder pain

To help avoid eye strain, here are few tips for working from home:

  • Record time spent on screens – Most adults age 18 and older spend at least 13 hours each day using digital devices. Extended screen time can cause discomfort and vision difficulties. When working from home, you may lose track of how much time you’re on your computer or smartphone.  So keep track of the hours you use devices. That way, you’ll be aware of the demand you’re placing on your eyes.
  • Rest and blink your eyes – Researchers found that over 30% of people using digital devices rarely take time to rest their eyes. Just over 10% say they never take a break, even when working from home. The eye muscles get overworked and don’t get a chance to relax and recover. Experts suggest the 20-20-20 rule; every 20 minutes, focus your eyes and attention on something 20 feet away for 20 seconds.  You can also get up and walk around for a few minutes.

 

  • Reduce exposure to blue light – In the spectrum of light, blue is more high energy and close to ultraviolet light. So, if you use screens throughout the day, ask your eye doctor about the value of computer glasses that block blue light. Reducing exposure to blue light may help lessen vision problems.  At home, using digital devices until bedtime can overstimulate your brain and make it more difficult to fall asleep. Eye doctors recommend no screen time at least one to two hours before going to sleep.

  

  • Sit up straight – Proper posture is important. Your back should be straight and your feet on the floor while you work. Elevate your wrists slightly instead of resting them on the keyboard.

 

 

  • Proper lighting – A setting that’s too bright (sunny backyard) or too dim (cavernous basement) can cause eye strain and headaches. Your screen should be bright enough that you don’t need to squint. A screen shield can help reduce glare.

 

  • Set up monitor properly – Make sure your computer screen is about 25 inches, or an arm’s length, away from your face. The center of the screen should be about 10-15 degrees below eye level.  Cut glare by using a matte screen filter. You can find them for all types of computers, phones, and tablets.  Increase font size or set the magnification of the documents you are reading to a comfortable size.

 

  • Consider computer glasses –For the greatest comfort at your computer, you might benefit from having your eye doctor modify your eyeglasses prescription to create customized computer glasses. This is especially true if you normally wear distance contact lenses, which may also become dry and uncomfortable during extended screen time.  Computer glasses also are a good choice if you wear bifocals or progressive lenses, because these lenses generally are not optimal for the distance to your computer screen.
  • Create Technology-Free Zones – These tips can help reduce eye strain when you’re forced to look at screens all day, creating technology-free zones in certain areas of your home, like the bedroom or bathroom. If you spend the entire day working on the computer, getting in bed and scrolling through social media until you fall asleep won’t do your eyes any favors.

Once you’re done for the day, truly unplug. Read a book or spend some quality time with family members without your phone.

 

  • Get an Eye Exam – If you have tried all these tips and eye strain is still an issue, it might be time to see an eye care professional to schedule an eye exam.  The exam may even detect underlying issues before they becomes worse.

 

 

 

 

 

Blinking – Why is it so important?

Blinking is something we all do every minute, whether we think about it or not. The average person blinks 15-20 times per minute, or about 1,200 times per hour.

So why do we unconsciously move our eyelids over our eyeballs so many times? Because it’s extremely important for your eyes and vision.

Although you may not think of blinking as a major component of your health care routine, if you didn’t blink for extended periods you’d be at higher risk of eye infection.  You would also have uncomfortable, dry eyes and would have decreased clarity of vision. The most important benefit of blinking is that it cleans the surface of your eye of any debris and washes it away with fresh tears. The thin coating of tears helps sharpen your vision, clearing and brightening the image your retina receives. Blinking also nourishes your eye with oxygen and nutrients, keeping your eyes healthy and comfortable.

Blinking wipes and renews your tear film, the smooth, moist layer covering our eyeballs.

The tears have 3 important layers.  The inner most is the mucous layer that contains ‘mucins’ to keep the tears attached to the surface cells of the cornea.  This material is produced by ‘goblet cells’ in the conjunctiva.  The next layer is aqueous or ‘water-like’ that is produced by the lacrimal gland located in the upper-outer quadrant of the eye region. Finally, the outer layer is lipid or ‘oil-like’ that prevents the other layers from evaporating. These lipids are produced by tiny glands along the lid margins, next to the eyelashes.  If any of these layers are absent or abnormal, then the cornea becomes vulnerable to damage.

The tears contain many protein components such as lysozyme, which function like natural antibiotics. The tear film also contains many nutrients and amino acids to nourish the cells of the cornea, which is the clear, dome-like structure on the front of the eye.

Besides keeping your eyes lubricated, the tear film also:

  • Helps form an almost perfectly smooth front optical surface on the cornea helping light to focus properly.
  • Washes away debris.
  • Transfers oxygen from the atmosphere to the cornea, since the cornea lacks blood vessels to deliver it directly.
  • Provides a pathway for white blood cells when there is an injury to the eye’s surface.
  • Prevents infection due to presence of lysozyme and other antibacterial enzymes.

Your eyelids also play a significant role, aside from protecting your eye and keeping things dark while you sleep. There is also a slight horizontal movement of the eyelid that pushes debris toward the tear ducts, which are the small openings at the inner corners of the eyes through which tears drain into your nose. That is why your nose runs when you cry.

Blinking exercises are a great way to keep your eyes moist. Blinking stimulates tear production and gives our eyes a chance to wash away any debris that has accumulated on the surface of the eye. Individuals who spend a lot of time on the computer or reading a lot tend to blink less often than they should. Therefore, if your eyes feel dry and irritated when using the computer or reading, then look away and do the following blinking exercises.

Blinking Exercises for Dry and Irritated Eyes:

  1. Close your eyes quickly and tightly. Squeeze your facial muscles around your eyes for three to five seconds. Open your eyes slowly and relax your facial muscles. Keep your eyes open for another three to five seconds and repeat the squeezing process five to seven times.
  2. Use the 10-10 rule and every 10 minutes look at away from your computer and intentionally blink 10 times. Then resume your activities.

Common Eye Problems in Winter

Winter time is here!! And as most people would expect, the holidays are a very popular time of the year. But the winter also comes with extreme temperatures, humidity and precipitation, so don’t let it affect your vision!

Be on the lookout for these common eye conditions this winter and hopefully, you will comfortably enjoy the season without any problems.

 

DRYNESS

Cold outdoor air and heated indoor air often have less moisture than other seasonal environments. In the winter, you may experience dry skin, chapped lips, and dry eyes due to this low humidity. Cold winter winds may also dry your eyes out. To learn more about dry eyes, visit the linked website at Dry Eyes.

To minimize the drying ability of winter air, keep yourself hydrated. Use non-preserved artificial tears several times a day. Running an humidifier in your home to improve the quality of your indoor air will help as well.

 

EXCESS TEARING

While some people experience a lack of tears in the winter, others have the opposite problem. Excess tearing and runny eyes can occur due to cold air, biting winds, or seasonal allergies. Pay attention to when your eyes tear up to determine the cause. If your eyes start to water when you step outside or when the wind blows your way, wear sunglasses or goggles to protect your eyes. Although it seems strange using additional artificial tears for teary eyes, nonetheless they can lessen this reflex tearing.

If you experience excess tearing and itching while indoors, try an allergy medication and appropriate eye drops to reduce the effect of seasonal allergies. If you cannot determine the cause of your watery eyes or if over-the-counter treatments have no effect, especially if the wateriness alters your vision, see an eye doctor.

 

LIGHT SENSITIVITY

Winter skies can seem dark and gloomy, but snowfall and ice create many reflective surfaces that can dramatically increase the amount of light that reaches your eyes. If you have sensitive eyes, you may experience even more blinking, discomfort, tearing and other symptoms in bright winter light.

Some individuals develop new light sensitivity during winter due to a condition known as “snow blindness”.  Always protect your eyes with UV filtering glasses or ski goggles when going outdoors for long periods of time, including when walking, shoveling snow, or other winter activities.

 

REDNESS

Harsh winter conditions can cause redness, tenderness, and inflammation in the eye area. You may have swollen eyelids or redness over the normally-white part of the eye (the conjunctiva which covers the white sclera).

This redness could result from dry eye or seasonal allergies. Use non-preserved artificial tears every 2-3 hours.  To reduce the discomfort of inflamed eyes, apply a cool compress, such as a damp washcloth and take an over-the-counter oral pain medication.  If your symptoms persist, see an eye doctor to determine the cause of the irritation.

 

VISION CHANGES

While many winter eye health problems result from increased light or decreased moisture, you can also experience eye conditions caused by cold temperatures.

If you notice vision changes while out in the cold, move to a warm area as soon as possible. Use non-preserved artificial tears every 2-3 hours to to keep your eyes moist. If your normal vision doesn’t return after 30 minutes or so, seek medical attention.

 

If you experience any of the seasonal problems listed above for a prolonged period, consult your eye doctor.

Keep Your Eyes Comfortable During the Cold Winter Months

Harsh weather conditions can reduce the natural moisture in your eyes and the irritation usually results in a burning or itching sensation that often leads to rubbing or scratching your eyes which can worsen the symptoms. Sometimes it feels like there is a foreign object in your eye and for some, dry eyes can even cause excessive tearing, as your eyes try to overcompensate for their lack of protective tears. Prolonged, untreated dry eyes can lead to blurred vision as well. Between the harsh winter winds outside and the dry heat radiating inside, our eyes are very quickly irritated and dried in the winter months.  The result is itchy, dry eyes that may cause pain, blurred vision, a burning sensation, or even watery vision as our eyes try to compensate for the dryness.

What Are The Symptoms?

  • Uncomfortable, stingy, burning or scratchy feeling.
  • Stringy mucus in or around your eyes
  • Increased eye irritation from smoke or wind
  • Eye fatigue
  • Sensitivity to light
  • Eye redness
  • A sensation of having something in your eyes
  • Difficulty wearing contact lenses
  • Periods of excessive tearing
  • Blurred vision, often worsening at the end of the day or after focusing for a prolonged period

10 TIPS TO KEEP YOUR EYES COMFORTABLE DURING THE WINTER MONTHS

Whatever the symptoms, dry eyes can cause significant discomfort during the long winters and relief can seriously improve your quality of life.

  1. To keep eyes moist, apply artificial tears/eye drops a few times a day. If you have chronic dry eyes, speak to your eye doctor about the best product for your condition.
  2. Drink a lot of fluids – keeping your body hydrated will also help maintain the moisture in your eyes.
  3. If you spend a lot of time indoors in heated environments, use a humidifier to add some moisture back into the air.
  4. Try to situate yourself away from sources of heat, especially if they are blowing. While a nice cozy fire can add to the perfect winter evening, make sure to keep your distance so dry eyes don’t ruin it. 
  5. Staring at a computer or digital device for extended amounts of time can further dry out your eyes. If you spend a lot of time staring at the screen, make sure you blink often and practice the 20/20/20 rule – every 20 minutes, look 20 feet away for 20 seconds. Use artificial tears often to lubricate eyes during long periods of using your eyes.
  6. Avoid air blowing in your eyes. Don’t direct hair dryers, car heaters, air conditioners or fans toward your eyes. In your car, direct heat to floor vents and away from your eyes once your windshield is defrosted.
  7. Stop smoking and avoid smoky environments.
  8. Don’t rub your eyes! This will only increase irritation and can also lead to infections if your hands are not clean.
  9. Give your eyes a break and break out your glasses. If your contact lenses are causing further irritation, take a break and wear your glasses for a few hours or days. Also talk to your optometrist about switching to contacts that are better for dry eyes.
  10. Protect your eyes. If you know you are going to be venturing into harsh weather conditions, such as extreme cold or wind, make sure you wear protection. Try large, 100% UV protective eyeglasses and a hat with a visor to keep the wind and particles from getting near your eyes. If you are a winter sports enthusiast, make sure you wear well-fitted ski goggles.

If you find that after following these tips you continue to suffer, contact your eye doctor.

The Way Eyes Work

9/16/14

Eyes are an amazing part of your body and not just because of what they do helping you see. The are also fascinating be because of the way eyes work. Here are 20 facts about how your eyes function.
Colorful eye - the way eyes work

End of the Day Syndrome

4/2/14

“Dr. S., my eyes are red and burning at the end of my work day.”

“Patient, what sort of work do you do?  Tell me something about your work conditions.”

“I am a computer graphics artist.  I sit and stare at my twenty-seven inch HD screen for hours on end gently adjusting the composition of each pixel.  My studio is air-conditioned but not humidified, so after some hours of work, I feel dry as a bone.”

“One more question…can you cry tears?  Say, when you peel and slice an onion?”

Rule of 20 - blinking

The need to blink

Blinking is a complex function of the eyelids that when completed results in a clean, refreshed, re-wetted corneal surface.  The tears that are washed across the outside of the eye with each blink bring oxygen and other nutrients to the outer cell layer aiding in the rebuilding and revitalizing of the surface tissue.

Blinking is characterized by a full sweep of the upper lid over the eye to meet the lower lid.  The completion of this motion is performed gently without squeezing.  And, to be effective full eye closure needs to be repeated fairly often.  Blink rates vary according to investigators but most sources report an average of between six and ten full blinks per minute under normal viewing circumstances.

The anti-blink problem of our generation

In olden times – say the years between 1750-1950 – the most aggravating problem to the ocular surface was a good book or intense study.  The reader would concern himself with the text at hand and slowly his eyes would dry until a “rest break” was necessary.

Environmental or vocational changes to our lifestyle over the generations have promoted reduced blink rates.  Most recently in this negatively developmental progression is the effect of the television screen, the CRT, the LED screen, the handheld and pocket computer on the blink rate.  It appears that as attention level increases, blinking suffers.  First the eyes close less, then incompletely, and finally rarely only when surface dryness drives the individual to desperate measures.  He must blink or (so he feels) his eyes will pop out of their sockets.

Adding insult to injury increasingly over the decades is air conditioning – both heating and cooling – when not humidified.  Staring at console screens in dry environs speeds the desiccation of the cornea and results in discomfort.

The surface of the eye is a biological system.  Living systems require some degree of moisture.  If the cells of the eye – or any biological surface — are permitted to dry out, they will die.  Dead corneal cells fall off the cornea and float in the tears on the surface of the eye until washed away with a blink.  Until the surface is cleaned the dead cells are considered by the eye to be foreign bodies with the consequent irritation and induced reflex to blink.

When cells die and fall off, the underlying nerve endings send pain signals to the nervous system.  The sensation can be felt as pain, burning, or mere irritation or itching depending upon the severity of cell loss.

How to handle environmentally induced dry eye

After the ocular surface is dry most treatments will seem to make matters worse:  to cause burning and stinging, perhaps, even more than the dry eye itself.  Any tear substitute, any amount of blinking will be irritating at first. But, that is really all that can be done at this stage:  wetting and blinking.

Prevention

As in many conditions, the best treatment, in fact a cure, for recurrent environmentally induced dry eye is prevention.  For the eye that has a naturally flowing tear supply, the act of blinking is the surest prevention to stinging and burning after a day’s work at the computer.  Additionally, many sources recommend using the ‘rule of 20’:  after each twenty minutes of work, look up from the text or away from the screen; blink and refocus on the page twenty times.  This repetitive exercise simultaneously re-wets the eye and relaxes the focusing mechanism of the eye.

The result is relaxed and comfortable eyes that can continue to provide important and high quality information for longer hours of work.

Help for Computer Users

Working long hours in front of the computer requires a fairly unchanging body, head and eye position which can cause discomfort.  Correct working position, periodic stretch breaks, frequent eye blinking, artificial tears for lubrication are all very important.  However, it’s not always easy to remember this when you are engrossed in work. Here are a few fun, free and easy-to-install “break reminders” to help:

WorkSafe Sam - break reminder
WorkSafe Sam
WorkSafe Sam is a desktop tool that provides stretching tips to help reduce eye and muscle strain for office workers (clicking on this link will open a file on your computer because this is a zip file).

Workrave is break reminder program that alerts you to take “micro-pauses” and stretch breaks.

Take Your Break is another break reminder designed to prevent or minimize repetitive strain injury, computer eye strain and other computer related health problems.  It has a friendly interface and a tray icon status indicator.  It runs quietly in the background, monitoring your activity and reminding you to take regular breaks.

And remember to blink.  Blinking cleans the ocular surface of debris and flushes fresh tears over the ocular surface. Each blink brings nutrients to the eye surface structures keeping them healthy. The flow of tears is responsible for wetting the lower third of the cornea. This is very important in KC, since this area is generally below the bulge of the cone and in many cases irritated by wobbly RGP lenses.  Maybe your job requires hours of work at a computer. Maybe you like to spend your free time surfing the internet. Whatever the reason, your body is probably feeling the effects of spending too much time staring at a computer monitor, which could result in Computer Vision Syndrome (CVS).  The most common symptoms are: eye strain, dry or irritated eyes,redness in eyes,difficulty in refocusing eye,neck pain,double vision,blurred vision, fatigue, and headaches.

Please join us on Thursday when Dr. Bezalel Schendowich will be providing a detailed insight into the importance of blinking, going beyond computer usage.
