What procedure should be conducted prior to the instrument screening?

The correct choice involves conducting an observation prior to the instrument screening. This step is crucial because it allows the examiner to gather initial insights into the individual’s visual abilities and performance in a natural setting. By observing the individual, one can identify any obvious signs or symptoms of visual impairment, which can influence the subsequent screening results.

Observation helps in understanding how the individual interacts with their environment and can highlight areas that may need special attention during the instrument screening process. It provides valuable contextual information that aids in making informed decisions about the need for further testing or specific interventions.

While other methods, such as writing tests or physical examinations, can provide useful data, they do not replace the immediate and qualitative insights gained from observation. Similarly, a visual history review is beneficial but may not yield the same level of real-time behavioral information as direct observation. Consequently, starting with observation aligns with best practices in visual screening protocols, ensuring a comprehensive assessment process.
