Cone Adaptation Test

The test consists of 15 2" x 2" (5 cm x 5 cm) red blue and white plastic chips designed to help parents teachers and doctors assess children’s visual difficulties in twilight. The test situation is not a formal test of night vision but gives useful information on visual adaptation to lighting changes.
