A child's vision develops significantly during the first year of life but continues to develop during the preschool years. When a child is born they have the mechanism for vision but need to develop the ability to see.
Infants
Newborns see primarily in black and white and shades of grey. Newborn have a preference for faces and will then develop interest in objects. It is important that in the first 12 weeks of life an infant has an eye health. This can be performed by paediatrician to check the health of the eye and check for cataracts. By 8 - 12 weeks an infant will start to follow objects visually. Between 2 to 4 months the infant will learn how to move their eyes to follow an object as opposed to moving their head to scan. This is the beginning of visual tracking and eye teaming (moving the eyes together in the same direction). By 4 - 5 months a child's eye muscles would have developed the ability to coordinate movements and 'cross - eyed' appearance should reduce. Another exciting development is that children are seeing in colour by 4 months.
Four to six months
Between four and six months children have started to roll, push themselves up, and attempt to move. They are also quite skilled at grabbing objects and bringing them to their mouths for exploration. Visual acuity or sharpness has often developed by six months.
Six to Twelve months
Between 6 and 12 months of age children develop visual perceptual skills and improve in their ability to judge distances. These skills have developed as the child's motor ability develops as they transition from crawling to walking. Eye-hand coordination also improves significantly during this time.:
Vision Problems in Children
- Myopia (shortsightedness) causes difficulty seeing distant objects clearly.
- Hyperopia (longsightedness) makes it difficult for a person to focus on close objects.
- Astigmatism causes objects to appear distorted and not sharply in focus.
- Poor co-ordination of the eyes
- Turned eye
- Poor eye-hand co-ordination
Signs of a Vision problem
There are many clues to a vision problem in a child. These signs include eyes blinking frequently, one eye turning in or out, red or watery eyes and squinting eyes whilst the child is watching television. Other common signs include the following:
