Are online eye tests any good?

July 1, 2020June 16, 2021

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

June 1, 2020June 16, 2021

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

May 1, 2020June 16, 2021

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

April 1, 2020June 16, 2021

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.

Flashes, Floaters, and Spots: What’s in my Vision?

June 1, 2019

Have you noticed tiny shadows cast upon objects you are looking at? Do you see small spots in your vision when looking at a clear or overcast sky? You may be seeing floaters and spots in your field of vision.

What is the spot in my vision?

It is completely normal to see spots or floaters in your vision. As you age the gel-like consistency in your eyes begins to dissolve creating floaters in the watery center of your eye. While you cannot see the particle floating in your eye, a shadow of these particles can be seen reflected in the objects you are viewing.

Do I need treatment for my floaters?

No, most of the time treatment is not required for floaters in the eye. The floaters and spots are harmless, and most will fade over time. If your vision is inhibited by large floaters, give our office a call to discuss options available to reduce these symptoms.

Why is there a flash in my vision?

When light enters your eye it sends a message to the retina, the retina then produces an electrical impulse which is sent to the brain. The brain interprets this impulse as an image. If the retina is tugged, torn, or detached from the back of the eye it is common to see a flicker of light. The flashes or flickers of light can be temporary or continue indefinitely depending on the severity of the retinal issue.

Is this ever a medical emergency?

Seeing a few new floaters is not an emergency, however, if you suddenly see a shower of floaters or spots this may be cause for concern. The sudden appearance of flashes of light could mean that damage is occurring to your retina. If any of these symptoms suddenly appear, call our office immediately to discuss with your eye doctor.

Conditions associated with eye floaters and flashes:

Bleeding inside the eye
Inflammation of the interior of the eye
Nearsightedness
Cataract surgery
Laser eye surgery
Diabetes
Eye infections

Eye Color & Genetics

April 1, 2019

Ever wonder why your eyes are blue, green, brown, or somewhere in between? The colored part of your eye, the Iris, contains pigmentation which determines our eye color. Your parents pass on chromosomes which combine to customize your eye color.

How eye color develops

Eye color is not as simple as other genetic traits. Three different genes contribute to your eye color. Due to dominant gene types, darker colors like brown overpower lighter colors like blue and green. Colors such as gray, hazel, and multiple combinations are not as common and are not yet completely understood.

Most babies are born with blue eyes, but did you know their eyes can darken for three years? Melanin is a pigment not present at birth, which develops with age and causes eyes to darken. The more melanin someone has, the darker their eyes will be.

Facts About Common Eye Colors:

Brown: Most common eye color worldwide. This varies between dark brown, light brown, and honey brown eyes.
Blue: People with blue eyes have less melanin in their eyes than any other color. Blue eyes are thought to come from a genetic mutation of one individual.
Green: Thought to be the most attractive and one of the rarest eye colors.
Hazel: The hue of hazel eyes changes based on what you are wearing and the type of lighting you are in. Hazel eyes host a variety of colors.

Changes in eye color

When your pupil changes size, the pigments in the iris of your eye compress or spread apart causing the color of your eyes to change. Your pupils change size for a variety of reasons including changes in light and the distance of the object you are focusing on. Emotions can also change the pupil size and iris color.

Heterochromia

Heterochromia is a condition in which a person’s eyes are different colors, caused by one eye having more melanin than the other. Typically, present at birth and is not considered an eye disease as it does not commonly cause vision problems.

Enhancing your eye color

Wear eyeglass frames to compliment your eye color and skin tone.

Example: Determine if you are “warm” or “cool” toned skin and eye color then match your frames with a complementary color.

Use eye makeup to bring out the color of your eyes.

Example: Pinks, purples, and silvers bring out the warmth in brown eyes.

Wear clothing which compliments or contrasts your eye color.

Example: Orange, red, and gold highlight the natural hue of blue eyes.

Choose hairstyles and colors to accentuate your eyes.

Example: Bangs and layers which frame the face draw more attention to your eyes.

Colored contact lenses give you the opportunity to try out a new look.

Reasons Not to Compromise on Price

March 1, 2019

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

February 1, 2019

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

December 1, 2018

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?

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

Combating Dry Eye Syndrome

November 1, 2018

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.
