Eyeglass Headform (50th Male)

 

Overview

The Eyeglass Dummy Headforms were developed from Alderson Research Laboratories’ VIP dummy heads. The VIP dummies were developed for automotive crash testing to comply with NHTSA requirements from 1966 through 1972. Modifications to the head and ears were made to enhance the headforms' ability to hold eyeglasses in place. The headforms were modeled from human subjects whose height and weight put them in certain percentile groups. These percentiles were developed from anthropometric surveys during and after World War II. Data supporting these percentile groups appears in:
