Introduction

In order for the vision screening test to be valid, the practitioner / technician must ensure that the environment is conducive to obtaining the best possible results. The suitability of the test environment should be determined before initial use and reviewed regularly to ensure it complies with the manufacturer’s requirements and current best practice.

Standardised equipment

Vision screening is conducted not only to comply with legislation but first and foremost to protect the individual exposed to visual hazards. Therefore, equipment of a certain standard must be used to ensure accurate readings and standard results. All vision screening equipment must be maintained; policies and procedures should be in place to ensure accurate readings and standardised results and hygiene protocols should be followed to ensure worker safety. In vision screening automated and manual equipment is required. Neither the manual nor automated vision screening equipment needs calibration.

Unlike audiometry and spirometry, there are no specific standards for vision screening or the vision screening environment. In this chapter, best practices and manufacturers guidelines are used to ensure the technician obtains the best result for each test performed. Remember as a vision screening technician or occupational health nurse conducting vision screening, our role is the possible identification but not the diagnosis of eye disease and conditions. It is expected that we identify the normal and through this will identify potential vision problems or abnormalities early and refer. Vision screenings are used to identify issues with visual functioning and sight.
