Keeping an eye on your preemie's development can help you determine when a little help might be necessary

It’s amazing how quickly babies grow and develop! The tables below highlight some important milestones. Although these tables give an average age at which milestones are achieved it is important to realise that even babies born at term achieve these milestones at varying ages. For preemies, you should always correct for their prematurity.


Visual Development in Infancy


Have a look at the following information for typical development of these visual functions. You should talk to your paediatrician if you have any concerns about your preemie's development.

Age Acuity, Colour Perception, Focusing, and Exploration Depth Perception
Pattern Perception Object Perception
Birth – 1 month
  • Visual acuity is 20/600
  • Scans the visual field and tracks moving objects
  • Responds to motion depth cues
  • Prefers large & bold patterns
  • Displays size and shape constancy
2- 3 months
  • Has adult like focusing ability
  • Perceives colours across the entire spectrum
  • Responds to binocular depth cues
  • Prefers patterns with fine details
  • Scans internal pattern features
  • Begins to perceive overall pattern structure
  • Perceives human facial pattern
  • Recognises mothers’ face in a photo
  • Uses motion and spatial layout to identify objects
4 – 5 months
  • Organises colours into categories like those of adults
  • Sensitivity to binocular depth cues improve
  • Detects subjective boundaries in patterns
  • Uses motion cues to perceive objects as three-dimensional
  • Uses cues like shape, texture, colour to identify objects
6 – 8 months
  • Visual acuity improves to 20/100
  • Tracks moving objects with smooth, efficient eye movements
  • Responds to pictorial depth cues

9 – 12 months
  • Visual acuity continues to improve
  • Can make out a pattern formation without a full image

These milestones represent overall age trends. There are individual differences in the exact age at which each milestone is attained.(Berk, 2008)
