This study demonstrated how success in stereopsis and monocular acuity testing in the under‐fives changes with age. Monocular testing was least successful with 1–2‐year olds, while success with stereopsis testing increased linearly to 100% by 3 years. The differing patterns mean that a reasonable degree of success with one test or the other is likely whatever a child's age. Since the demonstration of either stereopsis or normal monocular acuities rules out the presence of any gross visual anomaly, the age‐appropriate use of the two types of testing will facilitate the early detection of any abnormality.
