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.

Get the Facts About Lazy Eye

Lazy eye, or amblyopia, occurs when one eye fails to reach normal visual acuity, even with prescription lenses. In most cases, this begins in infancy and early childhood. If left untreated, lazy eye can result in blindness, loss of vision, or the abnormal development of a child’s eyes.

What causes lazy eye?

Lazy eye occurs when one eye experiences fewer visual signals from the brain in comparison to the other eye. In prolonged cases, the eyes may stop working together and eventually the brain may completely ignore the input coming from the “lazy” eye.

Strabismus

Strabismus, the most common cause of lazy eye, is when an individual has a crossed or turned eye. Due to poor alignment, the brain begins to ignore the input from the poorly aligned eye resulting in strabismic amblyopia.

Refractive

Refractive amblyopia is caused by unequal refractive errors in the eyes. For example, if one eye has an uncorrected nearsighted RX and the other does not, an individual will experience blurred vision in only one eye. In this example, the brain will eventually neglect the blurred vision and causes amblyopia from lack of use.

Deprivation

Deprivation amblyopia is caused by articles on the eye, such as a cataract, preventing light from entering the eye.

Signs and symptoms to look for:

Because lazy eye begins at such a young age, it is difficult to pinpoint exact symptoms. However, as a parent, there are signs you should look for to determine if your child may have a visual disability. These include:

  • Crossed eyes or misalignment
  • If a child cries or fusses when you cover one eye
  • Trouble reading
  • An eye which wanders inward or outward
  • Poor depth perception
  • Squinting or shutting an eye

Importance of early detection

Lazy eye will not subside on its own and can worsen over time. If left completely untreated, lazy eye could lead to permanent visual problems. It is important to have your child’s eyes examined at an early age to catch any signs of lazy eye and seek treatment if needed.

Children should have their first eye exam at 6 months old, another at 3 years old, and again before starting school. Regular comprehensive eye exams help ensure your child’s eyes are developing normally and allow for early detection and treatment of eye-related conditions.

Myth or Fact

Bangs cause lazy eye. MYTH. Lazy eye cannot be caused by bangs or other cosmetic modifications unless it causes the eye’s line of sight to be blocked all day and night.

Patching is a common way to treat lazy eye. FACT.

Older children and adults with lazy eye cannot receive treatment. MYTH. An individual can receive treatment for lazy eye at any time. The effectiveness of treatment depends on a variety of factors including development stage and early detection.

The eye becomes “lazy” because the brain has decided not to process visual information from the eye. FACT.

Treatment is most effective if lazy eye is detected before age 7. FACT.

Eye Exams 101

Regular comprehensive eye exams are key to early detection of eye-related diseases to keep you seeing your best every day. Adults should have a comprehensive eye exam every 1-2 years. Children should have an eye exam as early as 6 months, before they start school, and then every 1-2 years. If you or your family need a comprehensive eye exam, contact our office to schedule an appointment.

We often get questions about what an eye exam is like, so we’ve created an overview of a typical eye exam in our office.

Eye Exam Basics

What does an eye exam test for? Eye exams test your visual acuity and the overall health of your eye.

Why is an eye exam important? Eye exams check for early signs of serious eye and health problems; some of which may not present with any symptoms.

Who gives an eye exam? Your eye exam is performed by a licensed eye doctor.

Terms to know:

  • Ophthalmologist: An ophthalmologist is a medical doctor (MD) who specializes in eye care. Ophthalmologists can prescribe eyeglasses and contacts but commonly specialize in treating medical conditions of the eye and performing eye surgery
  • Optometrist: Optometrists are eye doctors who prescribe glasses, contacts, vision therapy, and medication to treat eye diseases. Optometrists are not trained or licensed to perform eye related surgery.
  • Optician: An optician is not an eye doctor, but is an eye care professional who fits, adjusts, and repairs your eyeglasses. They can also help patients learn to apply, remove, and care for contact lenses.

What to prepare for your appointment?

Before your comprehensive eye exam, there are several materials you can prepare. First, create a list of all your prescription and non-prescription medications you take along with the dosage. This will help your eye doctor determine any vision risks you may have. Bring your most recent pair of eyeglasses or contact lenses, if you have them. Don’t forget to have a copy of your vision insurance card and other medical insurance cards with you. To learn more about the insurance providers our office accepts and other payment options, please call our office directly. Finally, bring a list of questions or concerns you may have about your eyesight to discuss with your eye doctor.

What to expect during your appointment?

Prepare for your eye exam to take an hour or more depending on the number of tests your eye doctor needs to evaluate your vision and eye health. A typical comprehensive exam is a series of visual tests to inform your eye doctor about your vision.

These tests help determine:

  • Sharpness of near and distance vision
  • Color blindness
  • Lazy eye
  • Ability to follow moving object and/or move between two separate fixed objects
  • Depth perception
  • Determine your eyeglass prescription
  • Structures of the eye
  • Glaucoma test
  • Eye drop test to look inside your eyes
  • Blind spots

What to do after the exam?

Following your exam, you will have the opportunity to explore the various frames and lenses found in our optical space. An optician will be available to assist you in selecting a pair of eyewear that best fits your lifestyle needs. If you choose to wear contact lenses, you will need to schedule a contact lens fitting appointment.

Once your new eyewear is ready to be picked-up, an optician will adjust your frame to fit you best and make it comfortable for everyday wear.

Finally, schedule your follow-up appointment for the next year. Regular comprehensive eye exams are essential in maintaining healthy vision. If you ever experience any sudden vision changes or eye injuries be sure to contact our office.

Eye Color & Genetics

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.

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.

What is a Black Eye?

A black eye forms when blood and fluids collect in the space around the eye causing swelling and discoloration. Typically, a black eye is considered a minor injury.

What causes black eyes?

A black eye is caused by bruising surrounding the eye, not inside the eye. This bruising is caused by broken blood vessels under the skin. A blow to the eye, nose, or head is the most common cause for a black eye, but surgical procedures near the eye or nose could also cause a black eye.

Symptoms:

  • Pain
  • Swelling
  • Discoloration
  • Headaches
  • Temporary blurry vision

How do I prevent black eyes?

You cannot always foresee an eye injury, but one way to prevent black eyes is to wear protective eyewear. If the activities you participate in require or recommend eyewear, such as safety glasses, face shields, or goggles, abiding by these recommendations and wearing eye protection will significantly decrease the risk of a face or eye injury and can keep you in the field or in the game.

How do I get rid of a black eye?

Typically, most black eyes heal on their own within one to two weeks. While healing, the black eye will change color varying in shades of purple, blue, green, or yellow. There are, however, a few steps you can take to help the healing process and relieve pain.

  • Apply a cold compress. A cold washcloth, bag of peas, or chilled spoon can help to alleviate pain and bring down swelling within the first 24 hours.
  • Taking pain medications such as acetaminophen or ibuprofen can help to relieve pain.
  • Apply a warm compress. After applying cold packs for the first day or two, apply a warm compress to the eye to increase blood flow in the area.
  • Lightly massage the area surrounding the bruise a few days after injury.
  • Snack on pineapple. Pineapples have enzymes to help reduce inflammation.

If your black eye does not subside, vision changes, bleeding occurs within the eye, or you notice other signs of infection, schedule an appointment or give our office a call. This could be a more serious issue that should be examined by an eye doctor.
