Which of the following statements is false regarding vision screening?

The statement indicating that vision screening is a diagnostic procedure is inaccurate because vision screening is fundamentally a preliminary assessment rather than a diagnostic one. The primary goal of vision screening is to detect individuals who may have vision problems that require further evaluation; it does not provide a definitive diagnosis of any vision impairments or eye conditions.

In contrast, other choices accurately reflect the nature of vision screening. For example, it indeed helps identify students in need of corrective eyewear, making it a valuable tool in early detection especially in school settings. Furthermore, vision screening is a non-invasive method, allowing for quick checks without any invasive procedures or extensive equipment. Lastly, it serves as an essential routine part of health checks, occurring regularly in schools and clinics to promote good vision health among populations.
