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.

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.

Vision Development and Children

Childhood is a critical time for vision development. Nearly 80% of what a child learns in school is presented visually. Arguably making vision the most important of the five senses. Visual skills start developing during pregnancy and continue to evolve and develop as a child grows. Undetected vision problems can cause developmental and educational delays in children.

Infant Vision Development

Your infant’s vision starts developing during pregnancy. It is crucial that toxins are not consumed during pregnancy as they can cause serious vision problems. At birth, babies only see black, white, and shades of gray. Infants are unable to focus on objects for several months and can only see the outline of objects.

As infants grow, they can distinguish between high contrast colors. By six months your child can see color, has sharper vision, and has begun developing hand-eye coordination skills. Schedule your child’s first eye exam at six months to make sure their eyes are healthy and on the right developmental track. Detection of eye health issues and vision problems at this stage in development can help to ensure your child does not experience setbacks in learning and growth.

When your infant begins to crawl and potentially walk they are learning to coordinate their body movements and their vision. Over time, your child will become better at judging distances. However, this is also a time when your child may grow more injury prone because they are exploring their environment. Bumps, bruises, eye injuries, and other injuries can occur which is why it is so vital to ensure that your infant’s vision is on track to prevent these injuries as much as possible.

Early Childhood Vision Development

During these years your child will be growing, developing, and improving their visual skills. It is recommended to schedule your child eye exam at three years old. Even if you don’t think your child has vision problems, your child is growing and changing. A comprehensive eye exam before your child enters school provides enough time to catch and correct any vision problems.

They are discovering how to integrate their vision and body position to complete new tasks. They learn this through playing games, throwing a ball, and riding a bike. Children are also working on developing their fine motor skills. The primary way preschool age children are learning this is through writing their name and the alphabet.

Between the ages of 3 to 6 is when you, as a parent, may begin to notice signs of a vision problem. If your child complains about headaches or tired eyes, this could potentially be due to a vision problem. Signs of vision problems include squinting, tilting the head, frequently rubbing eyes, and closing one eye to see. Additionally, look for sitting too close to a tv, holding a book too close, or avoiding activities that require near or distance vision. Some of these activities include coloring, reading, playing ball, or tag if you notice these signs in your child schedule an eye exam as soon as possible. Correct their vision before any learning is delayed!

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.

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.

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.

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.

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.

FAQ: Vision Therapy for Your Family

Vision therapy is often misunderstood. It has been misrepresented as some people have taken ideas about how vision works, coupled with real medical concepts, and tried to make their own vision “cures” while calling them “vision therapy.” Vision therapy is no one cure, and not even one treatment, but instead is a non-surgical, customized program created by a doctor and under his or her supervision. The process of vision therapy aims to correct certain vision problems or vision-related skills.

Because more people are asking for treatment options and bringing their children for eye exams earlier in life, vision therapy has become more well-known. We get a lot of questions about how it can help patients, so here are some answers to commonly asked questions about vision therapy.

I just heard about vision therapy helping a family I know. Is it new?
No, vision therapy is not new. Many of the activities and tools doctors use have been around for decades or more, but more people are asking about it and opting for vision therapy over surgical procedures when possible.

What conditions can vision therapy treat?
This is dependent on the patient’s unique situation, but vision therapy may be used to treat or improve problems like amblyopia (“lazy eye”), strabismus (“crossed eyes”), binocular vision problems with eye alignment, eye movement disorders, focusing disorders, or other visual deficiencies related to eye strain, eye fatigue, or problems derived from stroke or brain injury.

What does vision therapy do?
Vision therapy attempts to help focusing deficiencies and eye muscle imbalances, among other deficiencies. Vision problems can interfere with academic performance or impair the ability to comfortably read, so these coordinated plans try to improve these functions.

Is vision therapy only for children?
There are several kinds of vision therapy that include various treatments and exercises that may help you or your child. Vision therapy is more common for children because it is more likely that a child’s vision impairment can be aided when they are young, and more important to make sure development is not impeded.

Does it work?
This depends on many factors including the patient’s anatomy, the eye condition or deficiency, and how early the problem is treated. The only person who can assess the likelihood of vision therapy success is an experience eye doctor.
