Illinois Vision Certification Practice Test

True or False: A child with normal vision may fail a screening test due to a short-term allergy or fatigue.

1. True

2. False

3. Always

4. Not typically

The correct answer is: True

A child with normal vision can indeed fail a screening test due to temporary conditions such as short-term allergies or fatigue. Allergies may cause symptoms like itchy, watery eyes or blurred vision, which can interfere with the child's ability to focus or see clearly during the test. Similarly, fatigue can lead to reduced attention spans and diminished visual acuity, both of which can negatively impact the results of a vision screening. This means that a child who generally has normal vision might exhibit signs that suggest a problem if they are experiencing these transient issues, leading to a potential false positive result in the screening. Thus, the statement is true as it acknowledges that environmental and physical conditions can temporarily affect a child's vision test performance.
