Instruction
For adults, and children over eight years select the distance E-chart on the PEC Screen form.
Explain the vision screen using the distance E-chart.
- Expliquez à l'enfant que pour chaque E que vous lui désignez, il doit indiquer verbalement ou gestuellement dans quel sens la lettre est orientée.
Assurez-vous qu'il a compris et s'il se trompe, expliquez-lui de nouveau.
- Désignez un E sur la ligne supérieure (6/60) de l'échelle
- Ask the person to show or tell you which direction the E is facing up, down, left or right.
If a person is unable to understand or carry out the instructions, do not continue with the distance vision screen. Select unable to complete distance vision screen skip to eye health screen and refer to an eye health professional.

Question
If a person wears near vision spectacles, should they wear them for the distance vision screen?
Sélectionnez une réponse.
La bonne réponse est Non.
Near vision spectacles are for near vision activities like reading. A person does not need to wear them for a distance vision screen.
Instruction
Start with the person’s right eye and top line.
Ask the person to cover their left eye with an occluder (or palm of their left hand), leaving the right eye open to see.
Question
When explaining to the person how to cover their eye, should you ask the person to press their hand firmly onto their eye to make sure it is covered properly?

La bonne réponse est Non.
Il peut être dommageable d'appuyer sur l'œil avec la main. Il peut également être plus difficile de voir clairement avec cet œil quand on retire la main.
