Make sure your refraction equipment is polarization-compatible (please refer to manufacturer’s instructions).

Activate biocular balance by polarization :

1. Open the SiVIEW Exam application.
2. Click on the burger menu (icon on the top-left corner of the screen).

3. Select “Preferences“.

4. Ensure that the Biocular examination “by polarization ” option is activated.

1. Initial setup case history :

Select a subject aged 40, with no case history, a “deep” eye examination and a maximum binocular acuity ceiling of 15/10, follow the steps below to quickly access the polarization test :

2. Setting starting values :

• Enter values equal to 0 for each eye (OD and OS).
• Please enter the pupillary distance to begin the examination.

Please follow these steps to achieve biocular balance as quick as possible.

1. Examination of the right eye (OD):

• Read the visual acuity line of 10/10.

• Read the 12/10 visual acuity line.

• Answer “No” to the validation question.

• Select proposition 2.

• Select Same twice (the dots cloud question)

2. Examination of the left eye (OS):

• Read the visual acuity line of 10/10.

• Read the 12/10 visual acuity line.

• Answer “No” to the validation question.

• Select proposition 2.

• Select Same twice (the dots cloud question)

1.Binocular vision:

• Read the lines at 12/10.

• Answer “No”

• Answer “Yes”

2. Checking polarization:

Sit on the chair in the position of a patient undergoing an eye examination and look through the refraction head (keep your glasses on if you wear them).

• If you close your left eye, your Right Eye (OD) should see the TOP line.
• If you close your right eye, your Left Eye (OS) should see the BOTTOM line.

• Feel free to perform the test several times, successively hiding your left eye and your right eye, to ensure that each eye sees the correct line.

3. If you notice a polarity inversion

• In the event of polarity inversion (right eye sees downwards and left eye sees upwards), please contact us so that we can reverse the polarization.
