This study evaluated several commercially available glare tests using factors of measured visual performance loss and relevant clinical features. In addition, individual glare testers were subjectively rated by examining personnel as to clinical features important for use in an aeromedical screening, such as cost, training and space requirements, ease of operation and scoring, etc. The other procedures either demonstrated an inability to detect visual acuity changes under simulated glare conditions or exhibited undesirable clinical features for use in aeromedical glare screening. These data may be used in evaluating future glare testers. Guidelines are provided for incorporating glare testing into the aeromedical certification process.
Additional research is planned to identify specific glare problems in the aviation environment.
