Illinois Vision Certification Practice Test

An amblyopic child primarily relies on which type of vision?

1. Monocular vision

2. Binocular vision

3. Both equally

4. None

The correct answer is: Monocular vision

An amblyopic child primarily relies on monocular vision because amblyopia is characterized by decreased vision in one eye, often due to the brain favoring the better-seeing eye. In such cases, the child may not be able to effectively use both eyes together, which is essential for binocular vision. Monocular vision allows the child to see with the stronger eye, while the weaker eye does not contribute significantly to their visual experience. As a result, their visual system adjusts to favor reliance on the visual input from the functioning eye, leading to a dependency on monocular cues for perception. Other options involve the concept of binocular vision, which relies on both eyes working together to see depth and a fuller visual field. However, in amblyopia, the effectiveness of binocular vision is compromised, making it less relevant for the child. The choice indicating reliance on both types of vision is also not suited, as the amblyopic condition directly influences the ability to use both eyes effectively.
