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 affected by blue light.

Why You Need Multiple Pairs

Thanks to our busy lives, multiple hobbies, and all the activities in between, having multiple pairs of eyewear handy is a necessity. Even contact lens wearers should have alternative pairs of eyewear. But some of us still haven’t jumped on that bandwagon. If you’re still on the fence, here are a few reasons why it’s a great idea to have at least two pairs of eyewear:

Misplacement

We’ve all been there, searching for missing glasses just when we need them the most. An additional pair of eyewear can’t guarantee they won’t keep slipping through the cracks, but it will significantly reduce the chances of having to go without. Lost a contact lens and don’t have a replacement? Backup glasses can hold you over until your new contact lenses come in!

Style

Think about it: a night out on the town is going to call for more stylish eyewear than the amber-tinted lenses you wear at your computer desk. Funky frames may better showcase your personality, but a more neutral pair may be needed for professional situations. Having different styles of glasses removes this dilemma by giving you situation-specific options.

Protection

Chances are, your standard glasses aren’t going to adapt and darken in reaction to sunlight (unless you have photochromic lenses), so it only makes sense to invest in a pair of prescription sunglasses to protect your eyes. Polarized lenses are a good option, especially since the tint can be tailored to your specific sport or hobby.

Contact Lens Wearers

Plano sunwear is a must have for all contact lens users. Contact lenses do not protect your eyes from the harmful UV rays of the sun. We recommend plano sunwear that blocks 100% of UV rays for anyone who wears contacts.

Schedule an appointment with our office if you’re interested in investing in a second pair of glasses! We will help you find the best frames and lenses for your lifestyle!

Are online eye tests any good?

Have you considered getting online eye tests? The idea of being able to get an eyeglass prescription and buy glasses without a trip to the eye doctor may sound appealing. Before ditching the traditional eye exams, there are a few things you need to know!

Online Eye Tests

The most important thing to know about online eye tests is they do not evaluate the health of your eyes. Even if they are called “online eye exams,” these exams only measure your visual acuity and refractive error. Some online eye tests can check for contrast sensitivity and color blindness. However, none of this can tell the health of your eyes.

The only way to know the complete health of your eyes is through eye exams with your doctor. During an eye exam, your doctor can detect vision-threatening conditions such as cataracts, glaucoma, or macular degeneration. Early detection of these conditions can prevent vision loss and blindness.

Know The Risks:

  • Online eye exams cannot detect eye diseases
  • Improper testing can occur due to error or misreading instructions
  • Higher chance of getting incorrect prescription due to self-administered the eye test
  • If you think the prescription is incorrect, your only option is to pay again and retake the test
  • An eyecare professional is not present to answer questions or concerns

Validation of Online Eye Tests

The results of online eye tests have not been guaranteed to be accurate measures of your prescription. Due to this being relatively new technology, there have not been enough studies to determine the reliability and validity of online eye tests.

Additionally, many online eye tests say their technology is suitable only for people between the ages 18 and 40 who are in good health. The limitations of the eye test raise concerns to the overall validity of the test. For these reasons, we do not recommend them as your sole option for your receiving your prescription.

The best way to ensure your eyes are healthy, you receive the correct prescription, and get answers to all your questions is through face-to-face eye exams with your eye doctor. Our staff of trained eyecare professionals will help you through every step of the process. Our office is here to address any questions or concerns you may have.

Combating Dry Eye Syndrome

Do you experience itchy, burning, or dry eyes? You may be suffering from dry eye syndrome. Tears are necessary for overall eye health and clear vision, when there is insufficient moisture on the surface of the eye it can cause discomfort. Let’s looks at some common causes of dry eye syndrome, symptoms, and risk factors.

What are the causes of dry eye syndrome?

Tears keep the eyes surfaces moist and wash away dust, debris, and other microorganisms. Without constant, adequate moisture, dry eye will occur. Not enough oil in the tears causes them to evaporate too quickly, and without sufficient water production, eyes cannot maintain proper moisture.

Symptoms of Dry Eye Syndrome:

  • Scratchy or gritty feeling
  • Red eyes
  • Blurriness
  • Irritation from windy conditions
  • Sensitivity to light
  • Fatigued eyes
  • Problems with contacts
  • Excessive tearing
  • Heavy eyes
  • Sore eyes

Contact lenses and dry eyes

One of the most common complaints from contact lens wearers is their contacts make their eyes feel dry. If you experience dry eye symptoms while wearing your contacts or immediately after removing your contacts, talk with your eye doctor, as it is irregular to feel discomfort.

If discomfort occurs, it is possible you are using the incorrect solution with your contact lenses; not all solutions are made equally. Your eye doctor may also recommend you use eye drops to help temporarily relieve dry eye symptoms.

Another means to relieve symptoms is to change your contact lens type to a more breathable or moisture-focused lens, which is specially made to help retain moisture. You may also want to discuss with your eye doctor the option to switch from reusable contact lenses to single-use lenses. Single-use lenses will help prevent your lens from drying out and work to maintain moisture in your eyes.

Factors that Increase Risk of Dry Eyes

Dry eye symptoms stem from multiple risk factors, including health conditions, environments, and eyewear choice. If you are suffering from dry eye try some of the tips below to help reduce your symptoms.  

  • Computer use. Humans blink less frequently when working at computers, allowing for more evaporated tears. When working on a computer for an extended period of time, follow the 20-20-20 rule. Every 20 minutes, look 20 feet away for 20 seconds to give your eyes a rest.
  • Contact lens. Dry eye discomfort is a primary reason for wearers to stop using contacts. Use rewetting drops daily or talk with your eye doctor about contact lens types that work best for your eyes.
  • Indoor environment. Air conditioning, fans, and air heating systems can decrease the humidity indoors and cause symptoms of dry eye. Try using a humidifier in your house if you notice the air getting dryer.
  • Outdoor environment. If you are outdoors in dry or windy conditions, wear a pair of sunglasses or hat to reduce your exposure to the elements which can cause dry eyes.
  • Smoking. Can cause 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 greater risk for dry eye than men the same age.
  • Health conditions. Certain diseases have a higher risk of contributing to dry eye- such as diabetes or thyroid diseases.
  • Medications. Prescription and nonprescription medications can have dry eye as a side effect.

Why Your Children Should be Wearing Sunglasses

As you may know, the sun’s harmful ultraviolet (UV) rays can cause damage to your skin, but how often do you think about the damage these rays can cause to your eyes? What about your child’s eyes? At a young age, children’s eyes are still developing, and with the substantial time they spend outdoors, it is important to purchase sunglasses to protect their eyes from harmful UV rays.

What Are UV Rays?

UV rays or ultraviolet radiation is a form of electromagnetic radiation or energy. These rays are emitted from the sun as well as a few man-made sources, like tanning beds. A key factor in what makes ultraviolet rays so dangerous is our inability to see them. Ultraviolet rays fall outside the range of visible light for the human eye. To read more about UV rays, click here.

Your Exposure to UV Rays

Eye Development

The lens inside a child’s eye is still developing and is not as capable of filtering high energy rays similar to eye lenses in adults. This inability to filter and fully protect their eyes causes children to have a higher risk of damage from UV rays. Shielding your infant’s or child’s eyes from UV rays as early as possible will help prevent overexposure to UV radiation throughout their lifetime. For younger children and infants, a sun hat provides additional protection to their skin and eyes throughout the day as the sun shifts and in case they remove their sunglasses.

Environment

Exposure to UV radiation increases at high altitudes, tropical locations, and in reflective environments. Consider the level of risk in your environment and if protective eyewear should be worn. Here are a few environment aspects and how they could affect your exposure to harmful UV rays.

  • Altitude: At higher altitudes, the earth’s atmosphere is thinner and unable to provide the same protection from UV rays.
  • Location: As you move closer to the earth’s equator, the level of UV rays increase. If you and your family are visiting a tropical location near the earth’s equator, always wear 100% UV blocking eyewear when outdoors.
  • Highly reflective services: Areas with highly reflective services like pools, lakes, oceans, and snow reflect UV rays. Snow can reflect up to 80% of UV rays creating a higher risk of UV damage to your eyes.
  • Clouds: Keep in mind clouds do not block UV radiation. UV exposure can be high on cloudy days.

Time of Day

  • Time of day: UV levels are higher between 10 am to 2 pm when the sun is at its peak.
  • Setting: Highly reflective surfaces like sand, water, and snow provide a much higher risk of eye damage due to UV radiation.

Children’s Eyewear

We understand convincing your child to wear sunglasses can be a challenge. Use these pointers when talking with your kids about sunglasses! Don’t forget, you know your children better than anyone else, so some of these tips may not work for them.

  • Match the current trends. If your child loves a certain color, pattern, or shape, purchase sunglasses to match their unique style.
  • TV shows, young celebrities, and brands like Disney create sunglass lines to appeal specifically to children. That’s right, children notice and prefer brand named items just like teens and adults.
  • Keep frame in the family. If the child has an adult or sibling they look up to and admire, purchase your child similar sunglasses to what the adult or sibling owns. This will appeal to the child’s desire to look more like their older sibling or parent!
  • Let them do the shopping. Take children shopping specifically to pick out their very own special pair of sunglasses. The more they like their sunglasses, the more likely they are to wear them, and the better protected their eyes will be from harmful UV radiation from the sun.

Tips for Choosing Your Perfect Eyewear

Have you ever gone to pick out new eyeglasses, but been overwhelmed by all your options? Do you ever struggle to know what eyewear shape looks best on you? We’ve compiled our best tips for picking the perfect pair of eyewear to help make your decisions easier.

  1. Contrast your face shape

    • There are seven basic face shapes to review including oval, base-up or base-down triangle, oblong, square, diamond, and round. Eyewear should contrast your face shape but be in scale with your face size. Find your face shape below and try out our recommended shape frames

      1. Oval: wide or walnut-shaped frames
      2. Base-up triangle: frames with a wider bottom, light color or lightweight
      3. Oblong: frames with more depth than width
      4. Square: narrow frames and with more width than depth
      5. Diamond: cat-eye shaped frames or other detailing on the brow line
      6. Round: narrow frames which are wider and have a clear bridge
      7. Base-down triangle: frames with color or detailing on the top half
  2. Highlight your features

    • Pick your best or favorite feature and pick a frame to highlight it.
    • Some features to consider highlighting would be your eyes, hair, skin color, and face shape. For example, if you have blue eyes, try a blue frame to match and highlight your eye color.
  3. Match or complement colors

    • Your skin, eyes, and hair work together to create your overall coloring. Everyone has either a cool (blue or pink undertones) or a warm (yellow or orange undertones) overall color. Try a frame from our color list below to complement your coloring.
    • Warm coloring: camel, khaki, gold, copper, peach, orange, coral, red, or warm blue
    • Cool coloring: black, silver, rose-brown, blue-gray, plum, magenta, pink, blue, or tortoise
  4. Find the perfect size

    • Try on multiple pairs to see what size fits your face shape best.
    • If the frames are too small your peripheral vision will be limited and could potentially feel tight on the head. The frames should not pinch your nose, leave red marks, slide down your nose, or easily slip off your head. The tightness around your ears can be adjusted to get the perfect fit.  
  5. Match your frames to your lifestyle

    • Make sure your frames will work for every part of your life and will be a representation of you and your personality.
    • Pick frames to match your unique lifestyle and hobbies. Consider your common activities when choosing frames. For example, if you are more active you may want a pair of sports eyewear or a wraparound band. If you spend a lot of time on the computer, you may want eyeglasses with a tinted lens.
  6. Anti-reflective coating

    • An anti-reflective coating helps eliminate reflections on both sides of your lenses to cut down annoying glare and improve night vision.
    • Anti-reflective coatings allow for sharper, clearer vision with less glare. The lenses appear to be nearly invisible, giving the eyeglasses a more attractive appearance and allowing for better eye contact.
  7. Are weight and material important to you?

    • Frames are most commonly made of plastic, metal, or a combination of materials. This combination determines the longevity, weight, and average cost of a frame.
    • Key Features:
          • Stainless steel and titanium are long lasting
          • Metal frames often have adjustable nose pads
          • Metal frames can come in hypoallergenic materials
          • Plastic frames tend to be less expensive
          • Plastic frames are lighter
          • Plastic frames typically need less maintenance than metal frames
          • Flexible hinges allow the “arms” to bend more than regular hinges

The Importance of Sports Eyewear

Whether you’re playing or watching the game, one incident everyone dreads is an injury. Injuries can prevent players from finishing the game, or worse, end an athletic career. Protective sports eyewear helps to prevent injuries and allows players to continue to play their sport. In today’s world, many sports facilities and fitness clubs require athletes to wear proper eye gear in order to minimize injury.

Why is it important to wear protective eyewear?

Emergency rooms treat more than 40,000 sports-related eye injuries every year, and up to 90 percent of those injuries could have been prevented by using protective eyewear. Any sport in which a ball, racquet, or other flying object is present poses a risk for injury. However, injuries can also result from close contact with others in the way of pokes or jabs with fingers and elbows. Protective eyewear is important because it keeps your eyes safe from a variety of injuries. As an additional bonus, the sharper your vision, the better you will perform in your sport of choice.

Features to look for:

  • Various sizes and shapes designed to fit the user.
  • Customized to best suit the sport including reflective lenses, space for headgear, and wrap around bands.
  • User’s prescription can be added to the lenses, which allows for better clarity during the game and increased overall performance.
  • Lenses are often made of polycarbonate, an impact-resistant material, to protect eyes from high speed and high impact objects.
  • Sports frames are also made of impact resistant material and often come with rubber padding where the frame comes in contact with the head or nose.
  • Wraparound sports glasses help to ensure the eyewear remains in place for the duration of a sporting event and prevents dust or debris from entering through the sides of the glasses.

Get the Facts

Experts agree sports-related eye injuries can be prevented by wearing protective eyewear. Parents and coaches should ensure athletes are wearing safety glasses during sporting events, especially considering 43 percent of all sports-related eye injuries occur in children younger than age 15. Regular eyeglasses are not safe to use as protective sports eyewear because they do not have impact resistance and could shatter or break upon impact.  

It is imperative that protective eyewear properly fits the user. Resist the urge to buy children’s eyewear with “room to grow.” Purchasing protective eyewear too large for the user could cause eyewear to be less effective and increase the risk of injury. Additionally, be sure the user has not outgrown protective goggles as this increases the risk of injury as well.  

Sports using Protective Eyewear

  • Badminton: sports goggles with polycarbonate lenses
  • Baseball/softball: batting and baserunning- helmet with polycarbonate face shield. Fielding- sports goggles or sports sunglasses with shatterproof lenses and head strap
  • Basketball: wraparound sports goggles
  • Bicycling: performance sunglasses with anti-fog and anti-scratch lenses
  • Fencing: full face mask made of rigid metal
  • Field hockey: all players- sports goggles with a head strap. Goalies- full helmets and face masks
  • Fishing: polarized sunglasses
  • Football: polycarbonate shield attached to a helmet
  • Hunting and shooting: polarized shatter resistant shooting glasses
  • Ice hockey: full face helmet
  • Lacrosse: form fitting and padded face mask
  • Paintball: full face helmet
  • Racquetball: sports goggles with polycarbonate lenses
  • Skiing and snowboarding: ski goggles or wraparound polarized sunglasses with mirror coated lenses
  • Soccer: sports goggles
  • Squash/Tennis: sports goggles with wraparound frame
  • Swimming and diving: swim goggles and diving masks
  • Volleyball: sports goggles or sunglasses
  • Water Polo: swim goggles with polycarbonate lenses

Reasons Not to Compromise on Price

Have you ever been tempted to buy cheap glasses you see online or the reading glasses you found at a discount store? They look just as good as the prescription eyeglasses you paid full price for, right?

The hard truth is they are not the same as the high-quality prescription eyewear provided by our office. Unreliable eyeglasses are more likely to break, scratch, and discolor over time. Your goal should be to buy glasses that will last and will not need frequent replacement. The cost of replacing cheap glasses can add up to the same cost as purchasing a more expensive, quality pair, originally.

Know what you lose

When comparing costs, there is always a compromise to be made. One of the biggest elements lost when buying cheap eyeglasses is individual care. Opticians recommend eyewear based on your daily routine, provide professional fittings, and ensure the quality of your eyewear is examined.

Same top quality?

Online glasses retailers often state that they offer the “same top quality” as eyecare practices. How do you know what their definition or range of top quality is? Cheap price often means cheaper materials.

Try before you buy

Usually, when buying glasses from an online retailer, you sacrifice the opportunity to try the glasses on and see how they fit your face. A virtual try-on does not allow for an accurate representation of how glasses look and fit on your face.

You cannot receive a proper fitting

If you choose to purchase eyeglasses from an online supplier, you forfeit a proper fitting. As a result, you may purchase a pair of glasses that are too tight or loose for your face.

Cheap frames

A downside to cheaper frames is they are more likely to cause skin irritation. Cheaper metal frames can discolor your skin or even cause a skin rash due to allergy. With prolonged wear, cheap plastic frames will discolor in sunlight and the smooth finish will diminish.

Durability

Another inevitable loss with cheaper eyeglasses is durability. Frames made with inexpensive materials are not designed to withstand extended use as well as eyeglasses sold by eye practitioners are able to.

Reading glasses

A wide-spread myth: all reading glasses are the same whether you purchase them at a discount store or at an eye practitioner. The truth is, your eye practitioner is able to customize the lenses to fit your exact eye and lifestyle needs. Read more about progressive lenses available at our office here.

Sunglasses lose UV protection

It’s tempting to buy cheap sunglasses because you are worried you might misplace or scratch them. However, it is crucial to protect your eyes from UV radiation damage. Don’t give up 100% UV protection for a cheap sticker price.

Know the Facts About Cataracts

Did you know, cataracts are the leading cause of blindness in the world? Cataracts affect nearly 20.5 million Americans age 40 and older.* If you are over the age of 50, you should have a yearly comprehensive eye exam to detect cataracts as they develop.

A cataract is the clouding of the lens in your eye. Many people describe the feeling as if you are looking through a foggy or frosted window.

What causes cataracts?

Clouding of the natural lens in your eye is caused by proteins clumping together within the lens. It is unknown why the eye changes as the body ages, but these changes may cause cataracts to grow larger over time, resulting in an increased difficulty to see clearly.

Some factors that have been linked to cataract development are diabetes, obesity, smoking, ultraviolet radiation, and family history.

Symptoms

Symptoms associated with cataracts can vary from person to person. However, there are a few key symptoms associated with most cases of cataract development. If you are experiencing one or more of these symptoms, schedule a visit with your eye doctor to discuss your risk or development of cataracts.

  • Slight blur in vision
  • Vision is cloudy
  • Sunlight or lamps feel too bright
  • Headlights have more glare and/or a halo around them
  • Colors no longer appear as bright as they once did

Types of cataracts

Subcapsular

Subcapsular cataracts typically occur in the back of the lens and are most common in individuals with diabetes or those taking a high dose of steroid medication.

Nuclear

Nuclear cataracts are associated with aging and occur in the central zone of the lens.

Cortical

Cortical cataracts occur in the lens cortex and are associated with streaks which interfere with light passage through the eye.

Congenital

Congenital cataracts are present at birth and may be due to genetics or intrauterine infection.

Are cataracts preventable?

No studies have shown a way to prevent cataracts, however, there are recommended practices to help maintain eye health and lower your risk of developing cataracts.

  • Yearly comprehensive eye exams help maintain eye health and detect the development of cataracts at an early stage.
  • Smoking has been linked to the development of cataracts. Quitting smoking provides a variety of health benefits lowering your risk for further cataract development.
  • Keeping up with treatment if you have diabetes or other medical conditions will help minimize your risk.
  • Maintaining a healthy diet, including fruits and vegetables, provides increased overall eye health.
  • Wearing sunglasses to prevent ultraviolet radiation will decrease your risk of UV damage which has been linked to the development of cataracts.

Preventing Snow Blindness, Sunburn for Your Eyes

We take many precautions to avoid sunburn on our skin, face, and lips, but have you ever thought about your eyes? Many are surprised to learn our eyes can also acquire sunburn. This condition is known as photokeratitis or snow blindness.

What causes Snow Blindness?

Snow Blindness occurs when your eyes are exposed to ultraviolet light for an extended period of time, causing sunburn. It most commonly occurs in snowy areas because snow reflects 80% of UV rays.* Snow blindness can also occur in highly reflective environments with water or white sand.

In addition to natural UV rays, man-made sources of ultraviolet radiation can cause snow blindness. Typically, man-made UV rays only damage your eyes when the proper eyewear is not being worn. This can happen when working with a welder’s torch or using tanning booths or sunlamps.

Can I lose my vision completely?

No, Snow Blindness is temporary and doesn’t cause actual blindness, it typically impairs your vision for 24 to 48 hours.

Symptoms of Snow Blindness

  • Eye pain
  • Burning, red, or watery eyes
  • Gritty sensation
  • Sensitivity to light
  • Blurry vision
  • Swollen eyes or eyelids
  • A headache
  • Glare and halos around lights

Risk factors for snow blindness?

You and your family are at an increased risk for snow blindness when involved in sports with highly reflective surfaces. When skiing, snowboarding, and snow sledding, you should ensure everybody’s eyes are protected with snow goggles that provide 100% UV protection.

Altitude plays a big role in the risk for snow blindness. At higher altitudes, UV rays are stronger. Therefore, when high altitudes, such as mountains, are combined with snow, the risk of Snow Blindness doubles.

Don’t forget, water sports such as water skiing, knee boarding, and surfing require protective eyewear as well. A great option is wraparound sunglasses that block out 100% of UV rays and remain on your head throughout the duration of the activity.

How do I prevent snow blindness?

  1. Anytime you are outside, you should wear sunglasses that block 100% of UV rays.
  2. Remember, UV rays can penetrate clouds, so sunglasses are required even on cloudy days.
  3. Always wear snow goggles when skiing, snowboarding, and mountain climbing.
  4. Wear wraparound sunglasses when you plan to be on or near water for extended periods of time.
  5. Ensure you have eye shields to wear in tanning beds and booths. Never tan without eye shields.
  6. Use the recommended safety eyewear for your job if you are working with harmful light.
