At what age do children generally reach a visual acuity of 20/20?

Children typically reach a visual acuity of 20/20 around the age of 7 years. This development aligns with the maturation of visual pathways and the ability to process visual information effectively. By this age, most children have developed sufficient visual skills for optimal performance in activities such as reading and writing, which require sharp vision.

While some children may have improved visual acuity at an earlier age, such as 5 or 6 years, the majority achieve the 20/20 mark by around 7 years, as their visual system continues to develop during this critical period. It's important to note that visual development involves various factors, including the growth of the eyes, cognitive development, and exposure to visually stimulating environments, all of which contribute to reaching this milestone at around the age specified.
