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.

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.

Nutrition and Your Eyes

The foods you eat and the dietary supplements you take affect your overall health and the health of your eyes. Nutrition and your eyes are linked together and can help prevent certain eye diseases along with other health problems.

Healthy Foods

Choosing healthy foods improves your overall health as well as your eye health. Dark green or brightly colored fruits and vegetables are essential parts of a healthy diet. These fruits and vegetables may also help to reduce the risks of developing eye diseases. Sugars and white flours may increase your risk of age-related eye disease, instead, opt for whole grains which do not have the same risks. Healthy fats containing omega-3 essential fatty acids are critical to your diet. These healthy fats can help prevent dry eyes and cataracts.

Hydration

Staying hydrated is essential to the health of your eyes. Drink plenty of water every day! We also recommend choosing healthy beverages and avoiding high sugar beverages. Proper hydration is linked to the reduction of dry eye symptoms.

Nutrients

Nutrients are an essential part of a healthy diet. These nutrients can be found in foods but can also be taken in supplements to ensure you are receiving the proper amount in your diet. Consult with your primary care provider before taking any dietary supplements. Here are a few nutrients that may have a link to eye health:

  • Vitamin A: may protect against night blindness and dry eyes
  • Omega 3 fatty acids: may prevent macular degeneration and dry eyes
  • Vitamin C: may reduce risks of cataracts and macular degeneration
  • Vitamin D: may reduce risks of macular degeneration
  • Zinc: may reduce risks of night blindness
  • Vitamin E: may reduce the risk of advanced macular degeneration

Aging Eyes

As you age, it is essential to consider all factors that could affect the overall health of your eyes. Not only should you adopt a healthy diet, but you can also do several other things to protect your eyes. One way to protect your eyes is to avoid overexposure to ultraviolet rays, which includes wearing sunglasses outdoors and staying away from tanning beds. Now is the time to quit smoking, not only is smoking harmful to your overall health it also increased your risks for many eye diseases. Finally, ensure that you are getting annual eye exams to detect any eye diseases before they cause permanent vision loss.

Nutrition and your eyes are highly connected, continue to find ways to feed your body the food and nutrients it needs to live a healthy life with healthy eyes.

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.

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

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.

FAQs: About My Symptoms

An overview and explanation of common eye symptoms.

Whether you or someone you know is suffering from a common eye-related condition, we know that you want the facts! Here are some of the most common questions and eye-related disorders we see in our office every day. If you are experiencing any of these eye symptoms or have questions about your eye health, give us a call to schedule your next appointment today.

Why are my eyes red?

Red or bloodshot eyes are a common problem caused by swollen or dilated blood vessels on the outer surface of the eye. Sometimes red eyes bother people because they are in pain, but that’s not always the case.

Potential causes of red eye include:

  • Allergies
  • Pink eye
  • Eye trauma

Why are my eyes itching?

Itchy eyes are one of the most common eye-related condition that patients experience. When an allergen (irritating substance) enters the eyes, your immune system responds with a natural defense mechanism by releasing a chemical causing the itching sensation.

Potential causes of itchy eyes include:

  • Allergies
  • Prolonged use of digital devices
  • Contact lens usage

How do I reduce my symptoms of itchy eyes?

To reduce your allergy symptoms try using eye drops to help lubricate your eyes. While rubbing can provide temporary relief it puts you at risk for damaging your cornea or adding even more allergens and bacteria into your eye.

Why are my eyes puffy?

Swelling around the eyes is due to excessive fluids in the skin tissue. As this fatty tissue gains fluid it begins to push forward and “bags” form under the eye.

Excessive fluid and puffy eyes can be caused by:

  • Allergies
  • Sinus problems
  • Dehydration
  • Overconsumption of salt
  • Fatigue or lack of sleep
  • Stress
  • Aging
  • Crying  

What is causing my burning, itchy eyes?

The sensation of burning eyes can be caused by a variety of everyday environments. For example, exposure to products such as makeup, facial cleansers, or shampoo may cause burning or itchy symptoms. Other factors like allergies, wind, and environmental irritants can also cause burning in your eyes. Keep track of what surroundings or products are causing these symptoms and try to reduce your exposure. If you live in a high wind or sandy environment, try wearing a pair of wraparound sunglasses to protect your eyes from the elements when outdoors.

I’m seeing spots and floaters, why?

Spots and floaters are a shadow in your vision caused by bits of protein and tissue in the gel-like matter in your eyes. It is normal to occasionally see spots or floaters in your vision and will become more common with age as the gel-like material in your eye begins to dissolve and liquefy.

I am experiencing eye pain, what should I do?

If you are experiencing prolonged eye pain or have a foreign object enter your eye, call our office immediately. It is important not to rub your eyes or try to remove the object yourself as this may irritate your eye further.

Describing Your Symptoms

Being able to describe the type of pain you are experiencing will help your eye doctor diagnose the problem. For example, pain behind the eye can be attributed to migraines or sinus infections.

Use descriptor from the list below to help describe the pain to your eye doctor.

  • sharp or dull
  • internal or external
  • constant or inconsistent
  • stabbing or throbbing
