3 Prepare the examination environment
To obtain the correct measurement values, we recommend that you perform
the examination indoors and avoid direct sunlight during the examination. If
the room has lots of windows, try to close as many curtains or blinds as
possible.
The brightness value should be 5 or below. If the value is greater than 5, the
flash cannot be turned on, and you need to reduce the brightness of the
surrounding environment. If the brightness is 5 or below, turn on the flash.
Then, you can start the procedure.
The examination environment must be quiet and free from distraction. The
subject must hold still during the procedure, so make sure that if the patient is
a child that they are able to hold still.
4 Check the examination distance
The recommended examination distance is 3-4 feet away from the device.
First, place the device at eye level of the subject, about 3-4 feet away from
their face.
Figure 3-2 Taking photos
Then, adjust the position of both the device and the subject to make sure that
their eyes are seen on the screen. Move the device back and forth until a
clear corneal reflection point is obtained. Then, you are ready to start the
measurement.

visible
To ensure that results are as accurate as possible, make sure that the subject
looks directly into the device during the examination. The subject should sit up
straight, with the body facing the camera.
Please remove glasses or contact lenses before starting the exam.
5 Start examination
To start the examination, tap the camera icon on the screen.
During shooting, make sure that the camera is oriented vertically, and keep
the camera at eye level of the subject.

In addition, in order to improve the stability and accuracy of the measurement,
we recommend that customers use the included tripod stabilizing device.
Remind the subject to avoid blinking during the examination, otherwise the
examination will fail.
The entire examination process lasts about 5 seconds. After the scan is
completed, a dialog box appears, as shown in Figure 3-5. You can tap Result
to check the examination results.
