Screen Time and Children

Screen time is the amount of time a person spends staring at digital displays including computers, tablets, smartphones, and TVs. In our modern and technology-focused world children are spending time on digital displays for educational and recreational purposes. Children who spend several hours on digital devices are at risk of developing vision-related problems.

Average Time Children Spend On Digital Devices

According to the Vision Council, 72% of American parents report their children regularly spend more than two hours on screens per day. It is likely that children spend significantly more time on screens than their parents think. Common Sense Media reports that children under age eight spend more than two hours a day with screen media. For 8 to 10-year-olds screen time triples to six hours per day. Kids in middle school and high school spend up to nine hours per day looking at digital displays.

Risks of Screen Time

Too much screen time can be dangerous for anyone’s eyes, children included. Screens emit a broad spectrum of visible light. While most of these light rays are harmless, blue light is a high-energy visible light that can cause damage to your eyes. Blue light has shorter wavelengths and higher energy causing harm to the retina over time. Overexposure to blue light can cause:

  • Difficulty sleeping
  • Headaches
  • Neck/shoulder pain
  • Eye strain
  • Reduced attention span
  • Poor behavior
  • Irritability

Computer Vision Syndrome

Computer vision syndrome is a condition caused by visual stress. Symptoms include tired eyes, dry eyes, headache, and fatigue.

Unhealthy Posture

Your body naturally slouches inwards when on digital devices. Your back and shoulders round, your head tilts back, and your chin justs forward. This reaction to digital devices is called “turtling” and can cause neck, back, and shoulder pain.

How To Protect Your Child’s Eyes

It is clear digital devices will not be going away anytime soon. Therefore it is essential to ensure you are doing everything you can to protect your children’s eyes from digital screens. One way you can do this is by limiting screen time for your children while at home. You can also apply blue light filters or download blue light filtering apps to all digital devices. If your child wears prescription glasses, ask us about add blue light blocking to their lenses during your next appointment.

Nighttime Use

The largest source of blue light is our sun, which tells our brain when to be awake or sleep. The high use of digital devices emitting blue light may disrupt your natural circadian rhythm (sleep cycle) by miscommunicating the time of day and if you should be awake or asleep. Stop digital device time two hours before usual bedtime to ensure your child’s sleep schedule is not affected by blue light.

Diabetic Eye Disease Awareness Month

November is Diabetic Eye Disease Awareness Month, which aims to increase awareness of diabetes and diabetic eye disease.  This month in particular, Dr. Mitchell would like to encourage people with diabetes to seek treatment for vision problems related to their diabetes. 

Diabetes is a chronic disease that is reaching near epidemic levels in our country.  Diabetes is a disease that results in the body losing the ability to process and use glucose efficiently.  In mild cases, just adjusting diet and activity level can help encourage healthy glucose use.  In advanced cases, the body may require use of oral medications to encourage glucose use, or injectable insulin to facilitate glucose processing.

If glucose isn’t regulated and used properly in our body, it can build up in the bloodstream.  Too much glucose in the bloodstream can prevent blood from properly delivering oxygen and nutrients to tissues throughout our body.  This can lead to blood vessel damage, and damage to sensitive tissues as a result of hypoxia, or not enough oxygen.  The smallest blood vessels at the end of the line are most susceptible to this kind of damage.  This is why damage can happen in the extremities, like fingers and toes.  

The blood vessels inside our eyes are among these smaller more vulnerable vessels that are prone to damage from chronic high or fluctuating blood glucose.  When blood vessels inside the eyes sustain damage, the surrounding tissue called the retina can suffer as well.  When the retina is damaged, it is called diabetic retinopathy.  Diabetic retinopathy includes bleeding of blood vessels inside the eyes, growth of new, faulty blood vessels in the retina, hypoxia of the retina (dying nerve tissue due to lack of oxygen), swelling or separation of the retinal tissue (particularly the macula which is our detailed central vision).  Any type of diabetic retinopathy can cause changes to visual clarity, and in some cases can lead to missing areas of vision and even blindness.

In addition to the problems from diabetic retinopathy, having diabetes makes other eye diseases much more likely to develop such as glaucoma, macular degeneration, and cataracts.

Vision problems and blindness related to diabetic retinopathy are often preventable, and in some cases reversible.  Close monitoring and management of blood glucose with a primary care physician or endocrinologist can prevent these problems from occurring.  If signs of diabetic retinopathy are noted, revision of diabetes management may help reverse course.  

The key to all of this is early detection and awareness.  If you know you have diabetes, you should be seeing an eye care provider at least annually for a detailed eye health and vision examination.  Often diabetes can be developing in early stages (sometimes called insulin resistance syndrome), and may be starting to influence vision without a person’s knowledge of the situation.  Dr. Mitchell regularly identifies people with diabetes.  This is based on early changes related to diabetic retinopathy that was detected in their eye exam.  Dr. Mitchell can then refer them to their primary care provider for further evaluation.

To recognize those who have lost vision from diabetes, and to encourage awareness of this growing issue, Dr. Mitchell is pleased to offer free diabetic eye screening throughout the month of November.  This screening will not replace a detailed, comprehensive eye examination, but will involve taking specialized images of the retinal tissue to look for obvious signs of diabetic retinopathy.  Dr. Mitchell will review and discuss these images with you and make recommendations about any further follow-up that may be important.

Call our office to schedule your free diabetic eye disease screening if:

  • You have diabetes but haven’t had an eye exam for a while
  • You have diabetes, keep up with your eye exams, and are just interested in reviewing your retinal health
  • You don’t have diabetes, but haven’t had a general physical for a while
  • You don’t have diabetes, but would like to learn more about your retinal health.

What Is Dry Eye?

Dry eye syndrome is caused by a chronic lack of moisture and lubrication of the eyes. Your eye’s tears keep the surface of the eye moist and lubricated, as well as washing away dust, debris, and other microorganisms.

What causes dry eye?

Typically dry eye occurs when there is a problem with your tears. Tears are made up of an oily, watery, and mucin component. Any issue with those components could cause dry eye. It could be tear instability, tear film evaporation, or insufficient tear production. The only way to detect the cause of your dry eye is an eye exam.


  • Burning sensation
  • Itchy eyes
  • Aching sensations
  • Heavy eyes
  • Fatigued eyes
  • Sore eyes
  • Dryness sensation
  • Red eyes
  • Photophobia (light sensitivity)
  • Blurred vision

Who gets dry eye?

Dry eye can happen to anyone at any age. Each case of dry eye varies in severity and individual tolerance. However, there are certain factors which can increase your risk for dry eyes. These factors include:

  • Computer use: Humans blink less frequently when working at computers, allowing for increased tear evaporation.
  • Smoking: Causes eyes to dry over time and is the root of various other eye problems.
  • Aging: Dry eye syndrome is more common after the age of 50.
  • Menopause: Women who have completed menopause are at a higher risk for dry eye than men of the same age.
  • Health conditions: Certain diseases have a higher risk of contributing to dry eyes- such as diabetes or thyroid diseases.
  • Medications: Prescription and nonprescription medicines can have dry eye as a side effect.

Visiting The Doctor

Getting an eye exam by an eye doctor is the only way to know for sure you have chronic dry eye syndrome. Symptoms of dry eye can vary significantly from person to person and may even be symptoms of other eye problems. Personal perception of dry eye severity does not indicate whether or not an individual has chronic dry eye syndrome. Some individuals with mild dry eye may feel their eyes are very bothersome, while some individuals with severe dry eye may not consider their symptoms significant.

If you are showing symptoms of dry eye, schedule an appointment with our office as soon as possible. The only way to know the medical severity of your dry eye is through an eye exam.


Back-to-school Vision Care.

It’s hard to believe we are talking about back-to-school time already……it seems like our kids just got out! You’ve got lists of school supplies to acquire to make sure they are prepared for learning; but as we prepare our kiddos to hit the classroom and books again, it’s important to discuss how kids are seeing their world, and how their vision contributes to their learning.

Every child is different; this includes the way they learn. Some kids need to read information, some need to hear it, some need to teach it or experience it. For most kids, seeing is one of the most important fundamental elements in learning. In fact, teachers spend a lot of time teaching kids how to use their vision for learning. There are many ways that vision can impact learning.

1: Most of the time, when we think about vision, we think about seeing clearly. Can my child see the smart board from across the classroom…..or can she see the words in the book? Obviously, if a child can’t see clearly, he may not be able to participate fully in academic activities. Often children don’t report difficulty seeing because they aren’t aware that things should look different, and they develop ways to compensate, like sitting at the front of the class, squinting, or asking a classmate. Correcting visual clarity can help facilitate classroom involvement, but can also facilitate sports involvement. Clear vision supports safe and healthy play. Children have better and more accurate reaction times when they can see clearer.

2. Another way vision impacts learning is how efficiently we see…….believe it or not, vision, and comprehension of material are learned skills. Like walking, many children develop visual skills just by being in environments that require it. However, some children have difficulty developing accurate visual perception skills on their own. There are a number of factors that may get in the way of this development like reduced clarity of vision (see number 1), mis-coordination of the eyes (either they don’t point at the same place, or the brain can’t use both eyes simultaneously), or inability to adjust focus accurately.

Dr. Mitchell has 4 kids, and 3 of them have required very strong glasses since they were little. He knows how important it is for kids to see clear and the kind of impact vision can have on learning. Because of this, Dr. Mitchell is offering free vision screening to all school age kids as we approach the start of school in the next few weeks. A vision screening is a quick assessment that will help determine if your child may need further attention for their eyes to help in school. Dr. Mitchell will check for major vision or binocular coordination issues and will make recommendations if necessary. Regardless of insurance, there is no cost for this initial vision screening.

Make sure your children are ready to learn and call us at Mad River Eye Care today for a free vision screening. Next post, we’ll talk about screen use……..phones, computers, chrombooks and Ipads.

One Year in Mad River Valley!

Happy Anniversary! On July 9th, Mad River Eye Care will be celebrating one year in the Mad River Valley. Dr. Shannon Mitchell founded Mad River Eye Care in July of 2018 fulfilling his career goal of owning and operating his own optometry practice. Previous to Mad River Eye Care, Dr. Mitchell worked for 8 years at a larger practice in Stowe.

So why open a practice in The Valley? “I was looking for a place where eye care services were not easily accessible, and Waitsfield seemed to be central to just such an area. I wanted to provide a needed and appreciated service that no one else was providing. Opening in Mad River Valley has been a smart and fulfilling change for me.”

Dr. Mitchell partnered with Brothers Building in renovating the Robert Inverness Building, and feels lucky to have found such a prime location in Waitsfield. “Most of our patients note how comfortable and relaxed our office is. Brothers Building did an excellent job renovating the space to suite our technologically advanced capabilities while keeping it as inviting as your own living room.”

In addition to investing in the latest eye care technology, Dr. Mitchell recently added the capability of finishing glasses in the office as well, “this allows us to offer speedy and exceptional service on glasses.” Beyond glasses, Dr. Mitchell offers complete contact lens services for all types of contact lenses for any patient. Dr. Mitchell can also handle eye health needs, and provides comprehensive examinations for patients with diabetes, cataracts, glaucoma, macular degeneration and more. He can make time to see more emergent cases as well such as eye injuries, infections, allergies, or acute vision changes.

Dr. Mitchell appreciates the support of Valley residents in his first year in business here. In recognition of the community’s support, Dr. Mitchell will be donating a portion of glasses sales in July to the Mad River Valley Community Fund.

Be sure to watch our social media for chances to win Mad River Eye Care merch/goody bags.

Faster Service On Glasses!

In house finishing:  We are pleased to announce that we now offer in-house finishing on most glasses lenses.  This means that we’ve simplified the process of purchasing glasses.  Because we will be cutting, shaping and inserting lenses right here in the office, we’ll be able to deliver high quality glasses to our patients much sooner than in the past.

So far, our glasses process has involved sending a glasses frame to our lens production laboratory.  The lab measures the frame, manufactures the lenses Dr. Mitchell prescribed, cuts the lenses, and  inserts them into the frame, then sends them back to our office.  That process on average has been taking about 10-14 days.  In some cases up to 3 or 4 weeks!  

Because we no longer need to ship the frame to the lab for most orders, we cut a lot of shipping time out of the equation.  We measure the frame specifications here, order lenses from our lab, and only the lenses ship to us when they are prepared.  When the lenses arrive, we cut and shape them with our new state-of-the-art system from Santinelli International (  This allows us to have your glasses ready within a week, sometimes in just 1 or 2 days!  Because we are only shipping lenses one way, we are cutting down our environmental impact as well.

We partner with ZEISS ( ),  a leader in advancing eye care and lens technology for most of our lens products.  ZEISS lens materials are superbly crafted to offer the greatest in optical clarity, durability and protection from harmful types of light like UV and high energy blue light. 

Dr. Mitchell is excited to provide high quality in-house finishing service to our patients in the Mad River Valley, and welcomes you to purchase your next glasses here.  Give us a call, or stop in for more information!

Advancing eye care in Mad River Valley part 1.

We returned from Vision Expo East with some great new ideas and products for our office.

  • New products:

    1. We are excited to introduce Marc Jacobs designer frame line to our optical! We selected styles that we think will be appealing to the discerning eye glass wearer. We are impressed by the quality of the frames, and the forward style!

    2. We also added a new line for kids and teenagers called Swing. Swing created a special material free of artificial dyes which is also allergen free and very light weight. It is flexible and durable, and will be great for our underage population (has a lot of give, and should be break resistant!).

    3. We also added new styles of some of our favorite brands:

      1. Smith Optics– with new colors and twists on classic frame shapes and sizes, we are excited to offer Smith’s innovations in our office.

      2. Costa– we’re happy we decided to carry Costa, not only do they offer amazing products with cool styles and designs, but they have started a recycling program where we can send old lenses (from old glasses, or the demonstration lenses that come in the frames we purchase) to a recycling facility where they are made into protective eye wear like motorcycle shields and safety glasses.

      3. Shwood– Shwood is quickly becoming a favorite in our office with their unique integration of wood, abalone and shells, titatnium and wood/aluminum laminates. Shwood frames are hand-made in Oregon, and they continue to push the limits. We are excited to bring some of their new products to our office that incorporate slate, mushrooms, seashells, and flowers.

      4. Europa– Including: Scott Harris, Cote d’ azur, and Allan J. These lines maintain some of our staple fashion with edgy shapes, bold colors, and smaller sizes for petite faces. Allan Jay is new in our office, and brings a bold, modern/retro blend of style that’s daring, but not over-the-top.

We are truly excited to offer updated styles of glasses right here in the Mad River Valley! Check our blog post next week for updates on our lens production capability………….

Gettin’ Smart in NYC!

Mad River Eye Care will be closed on Thursday March 21 as we head to NYC! We’ll be attending one of the largest eye care conventions in the world….Vision Expo East. We just wanted to spend a little time discussing the benefits for us and our patients when we attend conferences like this.

  • Smarts:

    • Dr. Mitchell spent extensive time studying in school, and training to be an optometrist. He attained the doctoral level of education in optometry, and learned all the latest and greatest research and technology for eye care. Like any other tech-driven industry, eye care changes rapidly with improved technology, detailed research, and changing availability of care. To keep up with all the latest changes and innovations, Dr. Mitchell regularly attends educational conferences where he spends time in class updating his understanding of the latest clinical approaches to eye care, exploring new treatment techniques, investigating new products, and testing out new equipment and tools of the trade. Dr. Mitchell is particularly looking forward to investing in new equipment that will allow our office to produce lenses for glasses right on-site and will allow us to make glasses much quicker than our current process. At Vision Expo, Dr. Mitchell will be able to check out the latest lens production equipment……stay tuned!!

    • Ashley and Madison will be attending educational courses geared toward working in optical environments. They’ll be able to gain insight into glasses fitting, general eye health, office management, and patient care.

  • Practice innovations:

    • Lenses for glasses: As noted above, Dr. Mitchell will evaluate lens production equipment that will allow our office to create some types of lenses right in the office, and/or will allow us to speed up our production time so that our patients have their glasses quicker.

    • Glasses frames: We will be spending time visiting with some of our product vendors to make sure we have up-to-date styles and selection of glasses in our optical. We’ll be exploring new frame lines and will be increasing our inventory.

    • Contact lenses: Dr. Mitchell will be reviewing the types and brands of contact lenses he prescribes, and will be looking for innovations that can improve comfort, vision, and ease of use for our contact lens wearers.

Stay tuned to social media for updates on Vision Expo East and Mad River Eye Care!

Free vision screening over winter break!

Clear vision is important for learning. Dr. Mitchell knows first hand how un-diagnosed, and un-corrected vision problems can inhibit children’s ability to participate meaningfully in learning…..3 of his 4 kids require substantial vision correction.

Early in our educational system, children are required to see clear to be able to learn……think about learning to read, recognize letters and numbers, colors and shapes. Kindergarten through 2nd grade emphasize learning concepts that will help with more detailed learning down the road. For many children, vision develops alongside these other important milestones, however, it doesn’t always go smoothly. There are many problems with eyes and vision development that can stand in the way of learning. Dr. Mitchell is pleased to offer a free vision screening opportunity over winter break (February 25th through March 5th ) to help figure out if your children could benefit from a comprehensive eye health and vision examination, and potentially glasses or other intervention. Here are a few issues he will be looking for:

Nearsightedness (can’t see far……like looking at the white board in school).

Farsightedness (can’t see well at near, or requires extra effort to focus at near……reading, desk work).

Amblyopia (sometimes called ‘lazy eye’, one eye doesn’t develop clear vision).

Strabismus (eyes don’t align with each other…crossed, point away, one points up or down, this can impede depth perception and coordination).

Call our office to schedule your preschool through 8th grader’s free vision screening over winter break!

Give the gift of sight! Gift Cards on sale through Valentine’s Day.

For most people, vision is the most important of the senses. We experience so much of our world through vision. Vision contributes so much to our awareness of our place in the world, our balance, coordination, depth perception, and general awareness.

Everyone in the family should have regular eye examinations to maintain the greatest potential for clear vision. Dr. Mitchell uses state-of-the-art technology to ensure that you are seeing your very best…..and there is more to it that just a glasses prescription.

From now until Valentine’s Day, gift cards are 20% off! Give those you love the gift of sight!

Today’s post emphasizes some important components of a comprehensive eye health and vision examination performed by Dr. Mitchell. These are considered preliminary tests and give Dr. Mitchell a lot of information about your eyes.

  • Thorough review of you current health status :

    • Various health issues can contribute to vision difficulties. Problems like diabetes, high blood pressure, thyroid disorders, autoimmune disorders like arthritis, Lupus and Sjogren’s. Dr. Mitchell needs to know about these and will discuss how they could influence your vision.

    • Medications can influence how your eyes work. Dr. Mitchell reviews your current medications for any that could be contributing to vision problems….some medications even impact the health of your eyes as a side effect.

    • Family history of medical issues: some problems have strong genetic components. Dr. Mitchell can help determine if your family history puts you at a higher risk of vision altering/threatening concerns.

  • Thorough review of your current vision correction:

    • We measure your current glasses with a lensometer to determine the prescription of your current correction. Dr. Mitchell checks your vision with these to understand how they are working for your currently.

  • Visual field test (look for the lights and click the button):

    • This takes about 2-4 minutes, and helps to identify if there are any areas of your vision that are missing or compromised….this is not only helpful information about your vision, but some patterns of visual field loss can help Dr. Mitchell to identify if a more serious underlying issue is at play.

  • Eye pressure test:

    • We use the iCare tonometer as our primary pressure testing device. This is easy to use on almost everyone (even kids and people who are really sensitive about their eyes). This test doesn’t require eye drops, or puffs of air.

    • Eye pressure is a major factor in glaucoma, and so we check it at every examination. If we need to double check, Dr. Mitchell also uses a Goldmann aplanation tonometer.

  • Autorefraction and autokeratometry:

    • These are accomplished in the ‘hot air balloon test’.

    • Autorefraction is an objective measurement of the focusing quality of your eyes, and can help give Dr. Mitchell a sneak peak at how your eyes focus. This test will identify if you have nearsightedness, farsightedness, or astigmatism. Dr. Mitchell will use this as a starting point for detailed vision testing that will determine your glasses prescription.

    • Autokeratometry is a measurement of the shape of the front surface of your eye. This helps to screen for structural problems with the shape of your eyes like keratoconus. It also helps Dr. Mitchell in fitting contact lenses that are an appropriate size and shape for your eyes.

  • Optomap:

    • Dr. Mitchell offers a unique screening test called Optomap that takes a comprehensive image of the inside of your eye and allows Dr. Mitchell to see nearly all of your retina. The images can also be used to document eye health concerns with the inside of your eyes and allow for straightforward comparison at future examinations.

At Mad River Eye Care, we have the right tools, technology, and expertise to help you…..See clearer.
