Children’s Vision Screening Program

Spot Vision Screener

To detect any vision issues associated with:

• Myopia (nearsightedness)
• Hyperopia (farsightedness)
• Astigmatism (blurred vision)
• Anisometropia (unequal refractive power)
• Binocular Vision (eye misalignment)
• Anisocoria (unequal pupil size)

The Spot Vision Screener is a state of the art piece of equipment that takes a photo of the child’s eyes. It screens for Myopia, Hyperopia, Astigmatism, Anisometropia, Strabismus and Anisocoria. A technical report is produced, that can be downloaded from the device.

Visual Acuity

Purpose: To determine how sharp vision is a longer distances.

Visual Acuity is tested using a Lea Symbol Chart. From a 3m distance, the child is asked to the read symbols on a chart. They are asked to perform the task with both eyes together and then separately with their left and right eyes. This helps to determine how sharp vision is at longer distances.

Colour Vision Perception

Purpose: To determine if the child perceives colour as most people do.

Colour Vision is checked by asking children to identify the numbers on different coloured backgrounds, which determines whether colours are being perceived normally.

Stereo Depth Perception

Purpose: To assess the binocular function of the eyes at near tasks.

Depth Perception is observed using an image of a fly and animals in boxes. Wearing 3D glasses, the child is asked if they can see the fly jumping out at them and which animal is trying to escape from their box. This shows if a child can determine distances between objects and sees the world in 3D.
