Intended use
The EyeQue VisionCheck is a self-administered, mobile
application-driven refraction measurement device that provides
spherical, cylindrical and axis correction metrics of the eye. The
VisionCheck allows the tracking of vision changes over time and
generates estimated refractive corrections.
Description
The EyeQue VisionCheck is a self-administered refraction
measurement device that uses your smartphone to determine
EyeQue EyeGlass Numbers®: lens power needed to correct
nearsightedness or farsightedness as well as lens power and
axis needed to correct for astigmatism. Your EyeQue results are
safely stored in the cloud.
EyeGlass Numbers are not prescriptions. Personal vision testing
does not replace the need for an annual eye health exam by an
eye doctor.

For ages 18 years or older.
Activation with serial number
Each EyeQue device has a serial number. This number is used
to unlock your EyeQue app to ensure you are using a genuine
EyeQue device. Activation is a one-time operation for an EyeQue
member account. If the device is used on another account, this
number may need to be re-entered. Store in a safe place.

How to take your rst vision test
• Place your elbows on a flat surface to hold your smartphone
as steady as possible.
• Hold the smartphone at reading distance, and slowly move
it closer until the eye cup of the device touches your right
eye.
• You should see two lines, one red, and one green. Take a few
seconds to find these lines. If you do not see them, try gently
moving the device left and right, up and down. It takes some
practice and is an important part of getting accurate test
results.
• Once you see the red and green lines, open and relax your
left eye (untested eye) during the test. Most people find it
helpful to focus the untested eye on a large object at least 6
feet away.

11
• Tap on the (> <) or the (< >) button and overlap the red and
green lines completely, to form one solid yellow line.
• The buttons will vibrate slightly when your tap is
registered.
• Depressing the button for a longer period of time will
result in repeated step-movements of the lines.

Next/Rotate lines

12
• Once you are satisfied that the lines are overlapped, press
the “Next/Rotate” button for two seconds on the device.
• Continue looking into the device. The red and green lines
will be rotated at a different angle. Overlap them as you’ve
done for the previous test; press the “Next/Rotate” for two
seconds when you see one solid yellow line.
• Continue and complete all 9 measurements for your Right
and then the 9 measurements for your Left eye. Follow the
voice prompts.
• You may choose to save or discard a test result. Discarded
result will not be used in calculating EGNs.
EyeGlass Numbers®(EGNs)
• After taking at least three sets of saved vision tests with the
EyeQue VisionCheck, the app will display a set of EyeGlass
Numbers.

13
• See: What Can You Do with EyeGlass Numbers
Note: Although a minimum of three tests are needed, more
vision tests will result in better, more accurate EyeGlass
Numbers.

14
What can you do with EyeGlass Numbers?
We recommend using them for general tracking of your eyesight
over time and providing it to your eye care provider before your
annual eye exam for evaluation. EGNs can be used to order
eyeglasses from online retailers that do not require an eye care
provider’s prescription certification.
EyeGlass Numbers are not prescriptions. Personal vision testing
does not replace the need for an annual eye health exam by an
eye doctor.
Multiple users
One device can be shared with several users.

15
EGN calculations are based upon the results of several saved
tests for a given individual and are available on their personal
dashboard. As a result, each user must have a separate EyeQue
membership.
Clean between users
Clean the VisionCheck device eye cup with rubbing alcohol
between users. Remove and/or allow the rubbing alcohol residue
to evaporate before bringing the device eye-cup to the eye.
Contraindications
The VisionCheck device should not be shared with users that are
known to have, or exhibit signs or symptoms of, an eye infection.

other eye conditions, insufficient manual dexterity, or improper
