Which visual disorder may result in a child having difficulty with properly focusing on objects?

The correct choice is that all of the listed visual disorders may result in a child having difficulty with properly focusing on objects.

Amblyopia, commonly known as "lazy eye," typically occurs when the brain and the eye do not work together properly, leading to a reduction in vision in one eye. This disorder can create challenges with focusing, especially if one eye is weaker than the other, causing the brain to favor the stronger eye.

Hyperopia, or farsightedness, is a condition where distant objects may be seen more clearly than near objects. In children, this can lead to difficulty with focusing on nearby things, such as text in a book or what is written on a whiteboard in school.

Myopia, or nearsightedness, causes difficulty in seeing distant objects clearly while nearby objects can be seen more sharply. This condition leads to focusing issues, particularly when trying to see things further away.

Since each of these disorders can affect a child’s ability to focus on objects at different distances, it is accurate to say that all can contribute to difficulties in visual focus.
