When we measure the size, the outer edges, of a visual field, we bring the stimulus from behind and watch when the infant/child notices the movement in the peripheral visual field. When we test young infants, it is often difficult to balance attention between central and peripheral stimuli.
The visual angle subtended by the narrowest width of the strip eliciting an eye movement measures the visual acuity. The visual acuity in the newborn child is at least 6/120 (20/400) by opto-kinetic nystagmus [3] that improves in the first few months of life.
A visual field test checks for gaps where your child is unable to see and measures how sensitive the vision may be in different parts of the visual field. Visual field testing can help detect and monitor various conditions, including glaucoma.

If children are able to recognise and describe pictures or symbols, specific visual acuity tests can be used. These are designed for near and far distance. As children are near orientated the test should be performed at near, and distance visual acuity measured at no more than three metres.
Tangent screen or Goldmann field exam. You will sit about 3 feet (90 centimeters) away from a flat, black fabric screen with a target in the center. You will be asked to stare at the center target and let the examiner know when you can see an object that moves into your side vision.
