What Is The Process Of An Online Eye Exam

At-home eye exam

When you are in the process of an online eye exam, you need to have a smartphone, computer, and internet connection. Then you may follow the instruction on the website of the eye exam-taking companies. After that, you need to use any letters in the book to make sure they can test your eye problem. This may take up to 25 minutes and the result of the eye exam may come within 24 hours. The ophthalmologist will detect your problem and review your results. Then you may get a prescription to use eyeglasses or contacts anywhere.

Online Eye Exams Are Available Do They Work

Online eye exams are cheaper and easier than in-office visits, but experts say people still need to go to the eye doctor for more comprehensive tests.

First came the ability to have eyeglasses made online.

Now you can have an eye exam online, too.

The question to focus on is: Are these online eye exams effective?

According to the Centers for Disease Control and Prevention , only half of the estimated 61 million adults in the United States who are at high risk for serious vision loss saw an eye doctor in the past year.

About 14 million Americans aged 12 years and older report that they have a visual impairment defined as distance visual acuity of 20/50 or worse. Among them, more than 11 million could have improved their vision to 20/40 or better if they had refractive correction.

Opternative is a new company that offers eye exams online.

After patients take the online eye exam, they receive a physician-approved prescription within 24 hours.

An Opternative eye exam costs $40 for a glasses or contact lens prescription, or $60 for both. The companys service is available in 29 states.

According to a clinical trial done on 30 people and listed on the companys website, the Opternative eye exam is just as accurate as a traditional office exam.

Aaron Dallek, chief executive officer and cofounder of Opternative, told Healthline that his service uses the only technology registered with the Food and Drug Administration that provides physician-reviewed prescriptions.

Who Is Eligible For The Online Vision Test

The online vision test is intended for use by people between the ages of 18-55 located in an available US State between the prescriptiverange of -12 to +6 sphere, less than -5.0 cylinder, and less than +4 add power. Patients with underlying medical conditions or medicationimpacting their vision are not eligible for the online vision test.

Other Terms On Your Eye Prescription

Depending on the kinds of lenses you need, you may see other terms on your eye prescription, including:

CYL or Cylinder: This term is only relevant to people with astigmatism, and refers to the lens power needed to address it. Astigmatism means your eyes cornea or lens is not completely spherical. Therefore, patients with astigmatism need cylindrical rather than spherical vision correction.

Axis: Again, this is for people with astigmatism. Its the number on your prescription that determines the orientation of your astigmatism correction. Axis is measured in degrees, not diopters. The cylinder and the axis always go togetheryou cant have one without the other!

Add: Additional magnification. If you have age-related presbyopia, you may have difficulty reading text close up, and can reserve a section of your glasses lenses for some added magnifying power. Its sort of like having reading glasses built into your regular ones.

Prism: Sometimes, eyes dont move in alignment with one another, resulting in symptoms such as double vision.

To account for this condition, your doctor can add a prism to your lenses. The prism is placed in a certain position and orientation based on your prescription, which will also notate the direction of the prisms thickest edge, or base.

The prism will also have its own refractive strength, measured in prism diopters.

Apps To Find Out What Prescription Your Glasses Are


It is important to remember that at-home tests should not replace a medical eye exam or comprehensive eye exam carried out by a licensed optometrist or ophthalmologist.

A person looking to order new glasses with a current and valid prescription can consider some of the following companies for their prescription needs:

  • GlassesUSA smartphone application. The app allows people to use their smartphones camera to scan their current glasses to determine their existing prescription.
  • SmartBuyGlasses offers a similar tool to GlassesUSA, allowing people to scan their current glasses to get their prescription information.

For a sight test that results in a new prescription, a person may consider the following options:

  • Visibly: For a small fee, a person can get an online eye exam that can provide a prescription from an optometrist or ophthalmologist within 24 hours. Unlike GlassesUSA, this is an actual vision test a person can use at home.
  • lensabl: Again, for a small fee, a person can take an at-home vision test and receive a prescription from an ophthalmologist within 24 hours.

Pdcheck Determines Pupillary Distance

PDCheck was easy enough to almost be fun. You start by putting on these oh-so-attractive white frames and launching the PDCheck app. It will provide some prompting to guide you through how the process is supposed to run.

Then, you snap a picture of the frames on your face. That’s shown in the picture on the left, below. Once you have that image, you need to move the little green crosshairs so they’re over the T marks on the glasses. The image below shows the interface before I adjusted all the crosshairs.

Once you’re done, you hit the Confirm button. The app produces the PD data you’ll need to order glasses, as shown below.

And yes, I blurred out my PD numbers. There’s probably no reason to do so, but it feels like personal identifying information.

Bottom line is the PDCheck process was simple and easy, and way more accurate than trying to hold up a ruler in front of your face while looking into a mirror.

Get To Know Your Fsa Or Hsa

FSAs and HSAs are savings accounts that allow you to contribute pre-tax dollars from your paychecks for use on health-related expenses. Both an FSA and HSA can be used for prescription glasses and many other eye health expenses.

But before we dive into everything that is and isnt covered, lets get to know your FSA or HSA a little better. While the two programs can both be used to cover costs for many of the same things, there are some differences between these two types of accounts to keep in mind, including the maximum you can contribute each year and whether or not your funds will roll over from year to year.

Access your account or reach out to Human Resources at your place of employment to get the full scoop.

How Often Should You See Your Eye Doctor

The American Optometric Association recommends that you have an eye exam at least every 2 years if youre under 60 and every year if youre over 60.

Its important to have your vision and eye health checked regularly because some serious eye conditions, such as glaucoma, dont have noticeable early symptoms.

An eye doctor can test your eyes and detect changes early, which may prevent vision loss. The tests are quick and painless, and can also help detect the following eye conditions:

Do Online Exams Miss The Mark

At home eye exam

Dr. Mark Jacquot, vice president-clinical director of vision care operations for LensCrafters in North America, told Healthline that online vision testing checks how well a person sees at various distances.

It typically also includes a refraction, which is a test that measures a persons prescription for eyeglasses.

While these two tests are important parts of vision care, it is important to understand that online eye tests are not complete eye exams, Jacquot said. Online testing does not currently identify other vision problems, eye health issues, or underlying health conditions that a comprehensive, in-person eye exam will uncover.

Jacquot said a comprehensive eye exam typically includes an assessment of patient history and a measurement of eye function.

It also includes a tonometry test, which measures eye pressure and can indicate the person is at an increased risk for glaucoma.

More tests on external and internal eye health are also performed during a complete exam. These can include dilation, which can help detect conditions like age-related macular degeneration and glaucoma.

A peripheral vision test is another exam often included. Loss of peripheral vision may also be a sign of glaucoma.

Jacquot said he embraces technology and believes there are benefits in increasing access to vision screening. However, he does not believe there is a substitute for a comprehensive, in-person eye exam.

When was the last time you had your eyes tested? Regular eye exams can ensure healthy vision. Our eyes change as we get older, and this often goes unnoticed. The first sign that our vision is deteriorating is not always blurred or unfocused vision. Headache or eye strain can also indicate vision problems.

Better vision also means more quality of life, as sight is our most important sensory organ. 80% of the impressions we receive of our environment are obtained through our eyes. Having our eyes regularly tested by a qualified eye care professional should be a routine part of preventive health care not only for yourself, but also for the safety of other people if you are driving. In general, provided we do not have any existing or known eye problems, we should have our eyes tested once every two years.

Use the online ZEISS Online Vision Screening to check your eyes online. This online vision test was developed by ZEISS experts to allow you to test your eyes in an easy and fast way for free. At the end of the test you will then receive a recommendation indicating whether you should consult an eye care professional for expert advice. Start your online eye exam.

The ZEISS Online Vision Screening Test will provide you with a baseline of the current performance of your eyes.

Introducing The Eyeque Visioncheck

EyeQue is a Bay Area-based company founded by guy with a Ph.D. in atomic physics and the CEO of discount optical supplier Zenni Optical. Together, they put together a product and service offering called VisionCheck based on technology licensed from MIT.

According to an MIT profile, the licensed technology is a “patented smartphone eye refraction test using the inverse of the Shack-Hartmann method.” It’s a low-cost solution for estimating refractive errors in the human eye, developed as part of the MIT Media Lab Camera Culture Group. According to the school, “While Shack-Hartmann sensors measure localized slope of the wave front error using spot displacement in a sensor plane, the MIT technology has the user shifting the spots until they are aligned.”

All of that is incorporated in a small Bluetooth vision testing device that temporarily attaches to your smartphone. You stare into the device, which works in concert with an app on the phone, and based on where you see the intersection of a green and red line, it takes a series of measurements.


After ten measurements taken of the left eye and ten of the right eye, it spits out a series of numbers the company calls “EyeGlass Numbers.” These are specifications you can send to some online eyeware suppliers, and get back a pair of vision-correcting glasses.
