Children's visual development develops gradually during the first months of life. Immediately after birth, children recognise faces only like a template. Spatial vision and colour vision are also not fully developed.
Between the 3rd and 4th month of life, babies can perceive objects spatially and in the 7th to 8th month of life, three-dimensional vision is developed. By the end of the first year of life, babies have 50% of the vision of an adult.
Vision (visual field recognition) does not match that of an adult until the age of 10-12 years. This means that before this age, children have up to 30% smaller field of vision (visual field) than adults. This must be taken into account especially in road traffic.
The visual ability of children is tested at every age according to the development of their vision.
