At what age do infants typically develop the ability to fixate on an object clearly?

2 years
8 months
3 months
1 year

The correct answer is: 3 months

Infants typically develop the ability to fixate on an object clearly by around 3 months of age. At this stage of development, their visual acuity improves significantly, and they begin to demonstrate better focus on objects that are within their line of sight. They are able to track moving objects and show interest in faces, which further supports their social interaction and cognitive development. Prior to this age, their vision is primarily limited to close distances, and they may not be able to see objects clearly beyond 12 inches. After the 3-month mark, you can expect their fixation ability to continue to improve, allowing them to engage more effectively with their environment. The development of clear fixation at this age also coincides with increased coordination of eye movements, which is fundamental for further visual development and exploration of their surroundings.
