Online VCS Screening Test - Now Available

Take the Visual Contrast Sensitivity APTitude Test Today!

The online screening test is a measure of one of the neurologic functions of vision called contrast. Your corrected visual acuity must be better than 20:50. If you normally wear glasses, you should wear them for the screening test.

There must be adequate illumination. We use a light meter to confirm 70 foot-lamberts or more. Light from both the illuminated computer screen and an overhead light is usually sufficient. The test is taken with one eye covered and one open at a distance of 18” from the computer screen. You will do the test first with the left eye and then with the right eye. You need to make sure the distance from the screen stays constant at 18”. Some people have found that cutting a string to an 18“ length helps keep the distance correct.

Your score is recorded according to published criteria for VCS testing. It is a ”Pass/Fail,” though how well you do can be used to assess your improvement over time or worsening with re-exposure/repeat illness.

VCS APTitude Account Features:

  • Purchase multiple tests
  • Track your results over time
  • Receive a 30-day follow up email
  • Printable results for your physician
  • Results can be emailed to your physician upon request

VCS APTitude Test Pricing:

You need to know that the computer version of the VCS test is a screening test and is not used to diagnose any condition. If you are concerned about the possibility of a biotoxin associated illness you will need to be examined by a physician experienced in the field.

Five Common Glaucoma Tests

Early detection, through regular and complete eye exams, is the key to protecting your vision from damage caused by glaucoma. A complete eye exam includes five common tests to detect glaucoma.

It is important to have your eyes examined regularly. You should get a baseline eye screening at age 40. Early signs of eye disease and changes in vision may start to occur at this age. Your eye doctor will tell you how often to have follow-up exams based on the results of this screening.

If you have high risk factors for glaucoma, diabetes, high blood pressure, or a family history of glaucoma, you should see an eye doctor now to determine how often to have eye exams.

A Comprehensive Glaucoma Exam

To be safe and accurate, five factors should be checked before making a glaucoma diagnosis:

Examining. Name of Test
The inner eye pressureTonometry
The shape and color of the optic nerveOphthalmoscopy (dilated eye exam)
The complete field of visionPerimetry (visual field test)
The angle in the eye where the iris meets the corneaGonioscopy
Thickness of the corneaPachymetry

Regular glaucoma check-ups include two routine eye tests: tonometry and ophthalmoscopy.


Tonometry measures the pressure within your eye. During tonometry, eye drops are used to numb the eye. Then a doctor or technician uses a device called a tonometer to measure the inner pressure of the eye. A small amount of pressure is applied to the eye by a tiny device or by a warm puff of air.

The range for normal pressure is 12-22 mm Hg (“mm Hg” refers to millimeters of mercury, a scale used to record eye pressure). Most glaucoma cases are diagnosed with pressure exceeding 20mm Hg. However, some people can have glaucoma at pressures between 12 -22mm Hg. Eye pressure is unique to each person.


This diagnostic procedure helps the doctor examine your optic nerve for glaucoma damage. Eye drops are used to dilate the pupil so that the doctor can see through your eye to examine the shape and color of the optic nerve.

The doctor will then use a small device with a light on the end to light and magnify the optic nerve. If your intraocular pressure (IOP) is not within the normal range or if the optic nerve looks unusual, your doctor may ask you to have one or two more glaucoma exams: perimetry and gonioscopy.


Perimetry is a visual field test that produces a map of your complete field of vision. This test will help a doctor determine whether your vision has been affected by glaucoma. During this test, you will be asked to look straight ahead as a light spot is repeatedly presented in different areas of your peripheral vision. This helps draw a "map" of your vision.

Do not be concerned if there is a delay in seeing the light as it moves in or around your blind spot. This is perfectly normal and does not necessarily mean that your field of vision is damaged. Try to relax and respond as accurately as possible during the test.

Your doctor may want you to repeat the test to see if the results are the same the next time you take it. After glaucoma has been diagnosed, visual field tests are usually done one to two times a year to check for any changes in your vision.


This diagnostic exam helps determine whether the angle where the iris meets the cornea is open and wide or narrow and closed. During the exam, eye drops are used to numb the eye. A hand-held contact lens is gently placed on the eye. This contact lens has a mirror that shows the doctor if the angle between the iris and cornea is closed and blocked (a possible sign of angle-closure or acute glaucoma) or wide and open (a possible sign of open-angle, chronic glaucoma).


Pachymetry is a simple, painless test to measure the thickness of your cornea -- the clear window at the front of the eye. A probe called a pachymeter is gently placed on the front of the eye (the cornea) to measure its thickness. Pachymetry can help your diagnosis, because corneal thickness has the potential to influence eye pressure readings. With this measurement, your doctor can better understand your IOP reading and develop a treatment plan that is right for you. The procedure takes only about a minute to measure both eyes.

Why Are There So Many Diagnostic Exams?

Diagnosing glaucoma is not always easy, and careful evaluation of the optic nerve continues to be essential to diagnosis and treatment. The most important concern is protecting your sight. Doctors look at many factors before making decisions about your treatment. If your condition is particularly difficult to diagnose or treat, you may be referred to a glaucoma specialist. A second opinion is always wise if you or your doctor become concerned about your diagnosis or your progress.

Where Should You Live? This App Will Tell You

If you’ve ever struggled to figure out where to live and work, you might benefit from Teleport, a website and app that recommends cities based on your lifestyle.

Trying the web browser version for myself, I prioritized places good for remote work and quality of life options including “tolerant society,” “near water” and “travel with ease.” (I skipped the cost of living questions, the past decade, I’ve lived in Copenhagen and San Francisco, two of the most expensive cities on the planet. I’m used to exorbitant expenses.) Under the city infrastructure options, I chose “car-free life” and ignored “school quality” and “less traffic” since neither really applies to my life. I was surprised when it suggested I move to Lisbon or Geneva, two walkable, cosmopolitan cities I’d never considered.

Teleport grew out of the founding team’s own experiences living in various cities around the world, often working remotely across cities and time zones in North America, Europe and Asia. The software company, which is constantly expanding its product line, began with Teleport Cities, a service that uses big data to determine where an individual should be based. (They are tight-lipped when it comes to specifics about the algorithm.) Since then, the group has developed tools, including Teleport Runway, which helps compare the costs of starting and running a small business in various locations, and Teleport Directory, a resource list for finding services and people in your next home city, as well as international moving checklists and blueprints for how to manage professional teams remotely.

Currently based in Palo Alto, Calif., Teleport co-founder and CEO Sten Tamkivi shares his story with

Where did the idea for Teleport originate?

Teleport definitely grew out of personal pains. Between my two co-founders, Silver Keskküla and Balaji Srinivasan, and me, we had lived in a dozen countries already, and I personally had spent a large part of my career running teams spread between multiple cities. Most of our team knows the struggles of moving around all too well. [There are many aspects to] trying to stay informed about your next location and steps you need to take: the hours of research, 29 browser tabs open at a time, the lack of credible information and trying to remember everything that is important to you and whoever you're moving with.

Half of our team previously worked at Skype, which also plays a huge part in both what we are building as well as how we are doing it. Basically, if at Skype we were making the world a smaller place in metaphorical sense, at Teleport, we are getting to the next stage and moving people around physically. By the time we had 200 people, we already had 10 locations, so every week, there were some questions about where to hire the next people and where to open the next office.

What’s the elevator pitch?

Teleport moves people to their best place to live and work, based on their personal needs and preferences. We help you plan your life across the current and future cities you want to work and live in, and get in touch with the communities, employers and governments to make the next move.

What’s the user experience for Teleport Cities?

You tell us about yourself: choose the life quality aspects that are important to you, and also reveal a little bit about your financial situation, such as your area of work and monthly rent budget.

Based on this, Teleport Cities gives you a list of cities that match your preferences, including a breakdown of your match score (qualitative features of a city), and budget differences (the hard numbers) compared to your current city. If you’d like, you can change your info, or add or remove some life quality settings to get a more accurate match list.

Once you’re happy with your preferences, you can go ahead and explore your top cities. Our city profile pages contain a huge amount of interactive widgets that break down information about every quality of life aspect in that city that you could possibly imagine.

Data is nice, but local experience is also great. For any other questions, we have an Ask a Local community, easily accessible from each city profile, where you can ask locals about living in a particular city.

Teleport Cities gives a user a list of cities that match his or her preferences, each with a score. (Teleport)

What is the geographic range? Is it limited to certain cities, with plans of expanding to others?

It's completely global. We kind of even ignore countries as a division on a map and think of cities or urban areas everywhere as our unit of management. We started out with the 100 most creative cities around the world, and have now reached 265. We add new cities based on user votes, both to avoid our own bias and to make sure our product is as versatile as possible.

A third of our users come from Europe, a third from North America and another third from everywhere else, mostly South America and Asia. We have a quarter of a million accounts signed up and executed over a million searches in 2016.

What types of preferences can a user select in a search?

There are about 300 different data dimensions involved in the product, but some of the most popular examples are cost of living, quality of education, tolerance towards minorities, environmental quality, cultural activities, job availability, labor regulations and economic growth.

The tool provides a breakdown of each city's life quality score. (Teleport)

What are the most popular of your location optimization tools?

Teleport Cities is definitely our most used product, and the one we spend the most time developing. While at it, though, we’ve kept running into adjacent pains that our users need a solution for, and especially some that have been really easy to build as light little apps based on the data and infrastructure we already have for our core product.

Some of our more popular side products include Teleport Zen, an interactive moving checklist, Teleport Sundial, a coordination tool for remote teams, and Teleport Runway, a tool to calculate your startup’s runway budget and compare costs in different locations.

Are there any misconceptions about your suite of products?

Some people have been slightly confused at the sheer amount of products we have built in a very short time. I’ve even been invited to speak at a product conference on the topic of immaturely large product portfolios. While the Teleport Cities life search is our core, we’ve just felt a number of small, targeted apps on the side have allowed us to learn and experiment without bloating our core product with random features.

Luckily, we have a great user base that is very active in giving us feedback and letting us know immediately when something is wrong or hard to understand, which is great, because we can fix the issue as well as learn a valuable lesson.
