Which age range is particularly focused on for vision screening?

The focus on vision screening in the age range of 3-5 years is particularly significant due to the critical period of visual development that occurs during early childhood. At this stage, children experience rapid growth and changes in their visual acuity, depth perception, and overall visual processing. Early identification of vision impairments such as amblyopia or strabismus is crucial, as these conditions can affect a child's ability to learn and interact with their environment.

Screening during these years helps to catch any potential vision problems before the child enters formal schooling, where visual skills are essential for learning. The effectiveness of interventions and treatments is highest when issues are identified early, making this age range a key time for screening. In contrast, other age ranges may not align as closely with the milestones of early visual development and the need for timely intervention in the case of detected issues.
