At what age is 20/20 vision typically expected to be achieved?

• A. By age 4
• B. By age 5
• C. By age 6
• D. By age 7

Answer: (C)

The expectation of achieving 20/20 vision typically aligns with developmental milestones in the visual system of a child. Generally, by around age 6, most children have developed the visual acuity necessary to be classified as having 20/20 vision, which signifies normal vision.

Before this age, children's vision is still maturing. Infants begin to focus on objects around 2 to 3 months, and by school age, around 4 to 5 years old, their visual skills have improved significantly, but they may not reach 20/20 acuity until later.

While some children might achieve this level of visual acuity earlier, the majority do so by the time they are 6 years old. After the age of 6, vision tends to stabilize in terms of clarity and the ability to focus on distant objects. This is why age 6 is considered a benchmark for when 20/20 vision is typically expected.
