Figure 3-1 Entering subject information on the Home screen 12 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. 13 Figure 3-3 Clear corneal reflection points on the screen, with the eyebrows and eyelashes 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. Figure 3-4 Orientation of the AI-Optic Vision Screener during shooting 14 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. Figure 3-5 Shooting completed 6 View examination results After the scan is completed, the examination results will be ready within approximately 10 seconds. After you tap Result, the name of the subject, the date of examination, the spherical degrees and cylinder degrees of both eyes, and the pupillary distance are displayed. If the examination result is good, the system displays Passed in green, as shown in Figure 3-6. If any problem is identified, the system displays Referral Required in red, as shown in Figure 3-7. 15 Figure 3-6 Examination completed, with good examination results Figure 3-7 Examination completed, with a referral suggestion After each measurement, you can tap the Home icon to return to the Home screen. 7 Operations related to subject information 7.1 Input the information of a new subject You can input the information of a new subject directly on the Home screen. 7.2 Retrieve the information of an existing subject.

Restart in about 30 minutes. 3 The screen suddenly turns off The screen will automatically turn off when the device is idle for a specified period. This is to save power. You can touch the screen to wake it up. If the screen does not wake up, the device is powered off. You just need to power on the device again. Note: You can tap Screen-off Time on the Settings screen to change the automatic screen-off or power-off time. 4 Common reasons for measurement failure When the scan fails during examination, check the following possible causes in sequence. 19 Figure 4-1 Shooting failed 4.1 The image is not clear Cause: If the image is not clear, it's because the measurement distance is too far or too close. Solution: We recommend that you place the device about 3 feet away from the subject. Adjust the distance between the device and the eyes of the subject to ensure that the eyes of the subject can be seen on the screen. Then, move the device back and forth until a clear corneal reflection point is obtained and the eyelashes and eyebrows of the subject can be clearly seen on the screen. When the measurement distance displayed on the screen is 95-105 cm, you can start measuring. 4.2 The subject does not look at the camera Cause: When the subject is not facing the device, or looking away from the camera during the examination. Solution: Remind the subject to turn their body towards the camera, and look directly into the lens. Sit up straight, and try not to move or blink during the examination. 4.3 Glasses are found Cause: The subject has not taken off the glasses during the examination. Solution: Ask the subject to remove the frame glasses and restart the examination. 20 4.4 No pupils are found Cause: The subject has organic eye diseases such as corneal scars, turbid refractive media, cataracts, keratoconus, or retinal detachment, or the pupils of the subject are blocked by their cap, eyelashes, or hair. Solution: Proceed to the referral process in case of any eye disease. Make sure their hair or eyelashes are not blocked the eyes. 4.5 The brightness value is excessively large Cause: When the surrounding environment is too bright, the brightness value on the screen is too high. Solution: Close the curtains or blinds to block out external sunlight. Incandescent lights tend to affect the performance of the examination, but fluorescent and LED lights are okay. If the brightness value on the screen is less than 5, tap the flash icon to turn on the flash. 4.6 The measurement is not completed Cause: If the subject closes their eyes or blinks frequently during the measurement process, the process can read as incomplete. This can also happen when the Wi-Fi network is unstable. Solution: Remind the subject to remain still and avoid frequent blinking. If the issue is with the Wi-Fi, connect to another network and restart the examination. 4.7 Eyes are closed or blocked Cause: When the subject closes their eyes or their eyes are blocked by hair or other things, the examination will fail. Solution: Remind the subject to avoid frequent blinking or remove obstructions in front of their eyes. 21
