Distance vision screen
Chart
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.
- Explain that for each E you point to, they show the direction the E is facing with their hand, or by telling you.
Check they understand. Correct if necessary.
- Point underneath an E on the top line (6/60) of the chart
- 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.
Spectacles
Pregunta
If a person wears near vision spectacles, should they wear them for the distance vision screen?
Select one.
¡La respuesta "No" es la correcta!
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.
Pregunta
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?
Select one.
¡La respuesta "No" es la correcta!
Pressing down on the eye with the hand can be harmful. It can also make it more difficult to see clearly out of that eye after being pressed.
Carry out distance vision screen
Instruction
Watch the video of a health worker carrying out a distance vision screen for a person older than eight years.
Record result
Results using the distance E-chart are recorded in the same way as the HOTV chart.
The same number of letters must be matched correctly on the top line and bottom line using the distance E-chart and HOTV chart.
If the person achieves Yes to top and bottom lines, both eyes, check their age:
- Under 40 years skip to the eye health screen
- 40 years or older continue to near vision screen.
If No for either eye:
- Top line skip to the eye health screen and refer to eye health professional urgently
