The Dangers of An Online Eye Test

What are the dangers of an Online Eye Test

Logan Optical – What are the dangers of an Online Eye Test, Logan, Utah

An online eye test may seem like a convenient way to check your vision or get an eyeglass prescription but beware, these tests aren’t all they are chocked up to be. In fact, they may even be dangerous.

What is an online eye test really testing?

An online eye test is actually not an eye test at all but just a vision or sight test – and a partial test at that. It is designed to measure your visual acuity and refractive error (nearsightedness, farsightedness or astigmatism) and to determine an eyeglass prescription – which is the lens power needed to correct the refractive error in your vision.

Given that there is no one with medical training actually performing or checking the accuracy of the test, it is questionable how well the exam does even this. In fact, when an eye doctor does a refraction for glasses or contact lenses it also involves some judgement on the doctor’s part. The eye doctor will often adjust the prescription slightly based on the patient’s age, occupation or hobbies. The doctor may prescribe a prism in the lenses to help with binocularity and to prevent double vision in those who have deviations of the eye. There is no way an online exam can do any of this.

Further, a refraction is only one very small part of an eye exam and if it takes the place of a regular comprehensive eye exam by an eye doctor, you put your eyes and vision at serious risk.

The American Optometric Association is warning consumers about possible risks associated with online refractive eye exams. Such online sites tout convenience. But any alleged advantages come with risks, the AOA cautions.

Comprehensive Eye Exams

Even if the eyes see clearly and you have 20/20 vision, there may still be vision problems or eye disease present even without pain, blurred vision or other symptoms. What the online eye test fails to measure is your complete visual health and capacity (beyond just visual acuity), the curvature of the eye (which is needed for accurate lens prescriptions- especially for contact lenses) and an assessment of the health of the eye itself.

Just as we need regular medical and dental checkups as a part of preventative health care to prevent disease and maintain our health, we also need regular eye exams. A vision test does not suffice. A comprehensive eye exam will examine much more than just how well you see. It will also check for visual processing, color vision, depth perception and proper eye movement. It will measure your eye pressure, examine the back of your eye and look for early signs of eye disease or conditions such as glaucoma, macular degeneration, diabetes, tumors and high blood pressure – many of which threaten your eyes and vision if not caught early.

If you do have some vision loss, the doctor will be able to determine if there is any serious underlying problem that is causing the disturbance in your vision. If you don’t have symptoms that doesn’t mean there isn’t a problem. Many serious eye conditions develop gradually without any symptoms. Some eye diseases do not affect the macula, and therefore you may still have good vision even though there is a problem (such as glaucoma, early dry macular degeneration, early cataract, diabetes, blood pressure and even tumors). Many of these conditions threaten the eyes and even general health if not caught early and when undetected they can cause permanent and irreversible damage to your vision

Eye exams are the best way to detect these early and treat them before they develop into serious eye problems.

Whether online vision tests are inaccurate, misleading or simply insufficient, they can fail to provide essential information and can delay or prevent vision saving treatments. Additionally, you could be walking around with the wrong vision prescription which can cause unnecessary eye strain, headaches and difficulty.

Online Eye Test

No. Besides the fact that most eye exams are covered by insurance, the eye exam you are getting from an eye doctor is much more thorough and comprehensive than an online eye test, so you are not comparing apples to apples. The eye doctor’s exam uses real equipment and performs a complete and professional evaluation of your vision and eye health. There is simply no comparing this to a self administered test on a computer screen.
An online eye test may be touted as a time and money saving convenience however, that is hardly the case. An eye exam is a medical procedure that requires training, precision, and proper equipment. Anything less can put your eyes and vision at serious risk.

In addition to visual acuity testing to check your vision prescription, we will perform various procedures during your eye exam to inspect ocular health. Using advanced optics and high-powered magnification, our eye doctors will check for any abnormalities in your eye tissues. Comprehensive eye exams are the only way to discover the beginning stages of eye disease.

Why is it so important to catch eye disease as early as possible? Because the earlier you receive treatment, the easier it is to prevent vision loss and complications.

Eye Dangers in the Dorm – Eye Health for College Students

This knowledge includes eye and vision safety, as failing to take care of your eyes today could cause damage to your eyes and vision now and in the future.

So put down your text books for a second and learn these four simple lessons about protecting your precious eyes:

Blue Light Protection

College students spend a LOT of time in front of screens. From each class, homework assignment, and research project, to texting, tinder, netflix and gaming – life is largely digital. This comes with a slew of potential side effects known as computer vision syndrome, including sore and tired eyes, headaches, neck, shoulder and back pain, dry eyes and blurred vision, largely due to the effect of the blue light emitted from the screens. Research shows that blue light can also impact your sleep quality and may possibly be connected to the development of retinal damage and macular degeneration later in life.

There are a few ways to protect your eyes and vision from blue light and computer vision syndrome:

  • Use computer glasses or blue-light blocking coated lenses or contact lenses when working on a screen for long periods of time. These lenses are made to allow optimal visual comfort for the distance and unique pixelation of working on a computer or mobile screen, by reducing glare and eye strain. They also block potentially harmful blue-light radiation from entering your eyes.
  • Prescription glasses may be considered as well. Many students who never needed glasses previously experience eyestrain with extensive hours studying in university. A minor prescription can make a big difference in reducing eye fatigue and helping to improve concentration.
  • Implement the 20-20-20 rule by taking a break every 20 minutes to look at something 20 feet away for 20 seconds. This allows your eyes to pause from the intensity of the computer screen.
  • Depending on your environment, eye drops prescribed from the eye doctor may be helpful. Your blink rate often goes down substantially when you are concentrating on reading or computer work, which can cause dry eyes. Using eye drops and remembering to blink frequently can help reduce these uncomfortable symptoms.
  • Install bluelight filters on your digital devices to reduce the amount of blue light exposure. There are a number of free apps available to download on your phone or computer.

Widespread use of computers or phones with computer access may cause additional issues with eye strain. Some of these symptoms may include trouble shifting focus from computer documents to paper documents, and “after images” when you turn your glance away from the computer screen.

A college student should take eye strain seriously when symptoms include eye discomfort, headaches, double vision or a noticeable change in vision. While college students do not usually put health concerns first, the Centers for Disease Control and Prevention recommend regular eye exams for people of all ages.

How to use Contact Lenses

Many college students opt for contact lenses as they are convenient and great for the appearance, but they come along with responsibility. The busy days and late nights can sometimes make contact lens care difficult so make sure to plan ahead. If you wear contact lenses you need to make sure that you always get them from an authorized lens distributor and that you follow your eye doctor’s instructions for proper care.

Always follow the wearing schedule and never sleep in lenses that are not designed for extended wear. Clean and disinfect as needed, and don’t rinse them with anything other than contact lens solution. Failing to follow the proper use and hygiene for contact lenses can result in irritation, infections and even corneal scarring which can result in vision loss.

One-day disposable lenses can be a great option especially for college students as they offer ultimate convenience (no cleaning and storing) and optimal eye health.

Further, if you enjoy wearing contact lenses, then remember to get a proper fit from your eye doctor. Many “exclusive” contact lenses available online may actually be poorly fit and made from inferior materials. One size does not fit all.

UV Protection

Ultraviolet rays from the sun are known to cause long term eye damage and lead to vision threatening eye conditions such as macular degeneration and cataracts. Additionally in extreme cases of unprotected UV exposure you can get sunburned eyes, known as photokeratitis, which can cause a gritty, dry feeling, burning, swelling, light sensitivity, vision changes and sometimes serious pain.

These symptoms typically go away within a day or two. Wearing 100% UV reflective sunglasses whenever you are outside – rain or shine – is a first step to eye protection. A large brimmed hat to protect the eyes from exposure from the top and sides is also a recommended addition for sunny days.

Regular eye exams

To start off college with the right foot forward, it’s recommended to get a comprehensive eye exam prior to the start of the the school year, especially if you haven’t had one recently.

This way you can ensure that your eyes and vision are in top shape and, if you wear glasses, that your prescription is still accurate. The last thing you want to worry about when getting adjusted to college is problems with your eyes and vision.
It’s also recommended for students that are going away to another city to get a recommendation for a local eye doctor in case of an emergency. Most eye doctors know of colleagues located in other cities who they could recommend.

Just remember to think about your eyes because the better you take care of them now, the healthier eyes and vision you will have down the line.

If you are in front of a computer screen for Prolonged hours not uncommon among college students, this may result in a disorder known as CVS or Computer Vision Syndrome.

Ocular Migraines

Ocular Migraines

Migraine Awareness Month:

An ocular migraine is any migraine headache that involves a visual disturbance such as flashes of light, seeing stars or zigzags or the appearance of blind spots in the visual field. Ocular migraines can interfere with your ability to go about your daily tasks such as driving, reading or writing, however, the visual symptoms don’t last long and do go away completely once the migraine has passed.

What is an Ocular Migraine?

The term ocular migraine may refer to a couple of different conditions. Firstly, migraines with auras often have eye-related symptoms that precede the actual headache.

An aura is a physical symptom that is experienced usually within 5 minutes to an hour before a migraine comes on, and can include:

  • Blind spots (scotomas) or partial vision loss
  • Flashes of light, spots or zigzag patterns
  • Visual, auditory (hearing) or olfactory (smell) hallucinations or disruptions
  • Tingling or numbness
  • Mental fog, trouble finding words and speaking
  • These types of ocular migraines commonly appear by obstructing a small area of vision which spreads gradually over 5 minutes.

According to the World Health Organization (WHO), migraines “almost certainly” have a genetic basis, and some studies say 70 percent of people who suffer from the disorder have a family history of migraine headaches. Read More

A second type of ocular migraine is when you actually experience temporary vision loss or disruptions (flashes, blind spots, zigzag lines etc.) during or immediately following the migraine headache. Ocular migraines can also sometimes appear without any head pain at all. They may also be called eye, ophthalmic, or retinal migraines.

Ocular Migraines in Logan, Utah

What Causes Ocular Migraines?

Similar to classic migraines, the exact cause of an ocular migraine is unknown. Genetic predisposition seems to be a factor to some extent, and having a family history of migraines does put you at greater risk.

While they don’t know the cause, experts have seen that spasms in the blood vessels and nerve cells in the retinal lining at the back of the eye are associated with ocular migraine symptoms.

For some, there are certain environmental triggers, or a combination of factors, that cause migraines.

These differ on an individual basis but can include:

  • Stress
  • Bright lights or loud sounds
  • Strong smells
  • A sudden or drastic change in weather conditions
  • Eating, or exposure to, certain food substances such as, alcohol, caffeine, nitrates, MSG (monosodium glutamate), artificial sweeteners and tyramine.

Since triggers are different for everyone it’s advised to try to identify yours by keeping a journal to track your environment, diet and lifestyle habits, when you experience a headache.

Sunglass Lens Options

Once you are certain your sunglass lenses have the requisite UV protection, you can begin to consider other lens possibilities. Here are some other lens options to consider:

  • Polarized Lenses:

    Reduce glare from light reflecting off glass, water, snow, sand or pavement. You should consider polarized lenses if you participate in water or snow sports such as fishing, boating or skiing as the water and snow can create a strong glare. They are also great for comfort while driving by reducing glare and to enhance vision when on the road.

  • Tinted Lenses

    Certain lens tints enable you to see better or more comfortably under certain circumstances but you have to be careful. Lens tints can distort or reduce vision and some can even harm your vision by increasing your pupil size which leads to an increase of UV radiation penetrating the eye. Look for lenses with a medium tint that keep your eyes comfortable and do not have a negative impact on your vision. Your optometrists’ office can often make specific tint recommendations depending on your lifestyle or particularly activities (ex. golfing vs fishing) and the health of your eyes (for example, cataracts tend to cause more glare).

  • Photochromic Lenses

    Automatically darken when exposed to UV light. Photochromic lenses are a great option for individuals that wear prescription eyeglasses: one pair can serve you both indoors and outdoors. As soon as you step outside, the lenses will darken, and they’ll reverse when you go back indoors.

  • Lens Materials

    There are also a few options when it comes to lens materials, such as plastics – including polycarbonate or acetate; trivex – which is a polymer material; or glass. The type of lens will determine the durability, clarity of vision and price of your lenses, so you should consider the factors that are most important for you and try out a few options to see how they feel.

  • The recommendations are that eyeglasses should block UVA and UVB radiation,” said president of the American Optometric Association. When shopping for sunglasses, look for a tag or label that says 100% protection against both UVA and UVB or 100% protection against UV 400. Read More

    Sunwear Frames

  • Frame Size

    The size of your sunglass frame is important for both comfort and protection. Your frames should fit according to your face size and provide ample coverage for your eyes. When you try on your frames, make sure they cover your eyes and feel comfortable around the bridge and temples. Also check that they don’t slip off when you move your head down toward the floor.

  • Frame Materials

    Frames can be manufactured from a number of materials and, these days, frame companies are constantly innovating to come up with new and improved options. These materials vary in strength, flexibility, weight, comfort and price. You need to choose a frame material that is comfortable, safe, and functional and that suits your lifestyle and your fashion style.

  • How-to Guide for Buying Sunglasses 2018 in Logan, Utah

    Making the Purchase

    When purchasing sunglasses, keep in mind that your vision insurance may help to cover the costs when purchased at an optometry office rather than at a sports or recreation store. Check with your insurance and your local optical to find out about any discounts or coverage. Another advantage of purchasing from an optometrist’s optical is that the optician can help you to find the perfect pair to suit your eye and vision needs, as well as your lifestyle and fashion preferences.

    The good news about choosing the right pair of sunglasses is that there are ample brands, colors, styles and materials to choose from. So when it comes to your shades, don’t settle for less than optimal protection, fit and comfort for your eyes.

    Ask our Optometrist about Polarization, and if it might help you see better?

Here is a breakdown of some of the visual skills you rely on for athletic performance:
Visual Acuity: the ability to see clearly is one of the most important aspects of vision. To improve visual acuity your eye doctor can prescribe eyeglasses or contact lenses, as well as prescription sunglasses, swimming goggles and sports goggles.

LASIK or refractive eye surgery or orthokeratology may also be options for improving visual acuity without having to wear vision correction during play.

  • Dynamic Visual Acuity: the ability to see moving objects clearly.
  • Peripheral Vision: your side vision or the ability to see out of the corner or sides of your eyes when you are looking straight ahead.
  • Peripheral Awareness/Visual Concentration: The ability to be engaged in a task while having awareness of peripheral and other visual stimuli without being distracted by them.
  • Depth Perception: the ability to perceive the relative distance and speed of objects in your field of vision.
  • Visual Tracking: the movement of the eye that allows for the ability to follow a moving object, switch visual attention from one object to another or to track a line of text. This allows an athlete to “keep an eye on the ball”.
  • Focusing: allows for the ability change focus quickly and clearly from one distance or object to another.
  • Eye Teaming: the ability for the two eyes to work together in coordination.
  • Hand-Eye, Body-Eye Coordination: the ability of your eyes to guide your hands and body to carry out movements accurately and effectively.
  • Visual Reaction Time: how quickly your brain is able to interpret visual information and respond with the appropriate motor action.

If you are serious about your sport or require specialty eyewear for your job or hobby, it’s worth scheduling a specialty eyewear fitting with your eye doctor. In addition to safety and eye protection, top athletic and occupational performance requires optimal visual acuity as well as a number of other visual functions such as peripheral vision, depth perception and hand-eye coordination. Read More

Often we take the wonder of our eyes and brain for granted, not realizing all of the systems that must be in place in order for us to perform optimally in our daily lives… all the more so for top-notch sports performance (and these are just the functions that are related to your eyes!)

Typically, visual processes occur automatically, without us paying much attention to them, but they are skills which can be improved. If you feel that you or your child might have some difficulty with one or more of these visual skills, speak to your eye doctor. Through proper eyewear, exercises, nutrition and sometimes vision therapy, it can be possible to improve upon these skills and as a result, enhance your performance on the field. In fact, professional athletes often utilize a combination of vision therapy and nutritional supplements (such as lutein and zeaxanthin) to enhance their vision and reaction time for better performance on the field.

Additionally, you want to make sure – whether you have visual processing issues or not – that you protect your eyes properly. Unfortunately, many injuries occur from an over-confidence that the eyes are safe during sports. Speak to your eye doctor about the right sports safety eyewear to protect your or your child’s eyes during your favorite sports.
