Common reasons for measurement failure

When the scan fails during examination, check the following possible causesin sequence.

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 fromthesubject. Adjust the distance between the device and the eyes of the subject to ensurethat the eyes of the subject can be seen on the screen. Then, move the devicebackand forth until a clear corneal reflection point is obtained and the eyelashes andeyebrows 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.

The subject does not look at the camera

Cause: When the subject is not facing the device, or looking away fromthecamera during the examination.
Solution: Remind the subject to turn their body towards the camera, andlookdirectly into the lens. Sit up straight, and try not to move or blink duringtheexamination.

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 theexamination.

No pupils are found

Cause: The subject has organic eye diseases such as corneal scars, turbidrefractive media, cataracts, keratoconus, or retinal detachment, or thepupilsof the subject are blocked by their cap, eyelashes, or hair. Solution: Proceed to the referral process in case of any eye disease. Makesure their hair or eyelashes are not blocked the eyes.

The brightness value is excessively large

Cause: When the surrounding environment is too bright, the brightness valueon 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 andLEDlights are okay. If the brightness value on the screen is less than 5, tap the flashiconto turn on the flash.

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 issueiswith the Wi-Fi, connect to another network and restart the examination.

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 obstructionsinfront of their eyes
