Popis:	In the development of protective eyewear for military operations, conflicting constraints impact design considerations. Since protection is a key parameter, it is important to be able to quantify the impact of different levels of coverage of the visual field. The objective of this project was to merge two different techniques — (a) methodology to verify visual field coverage and (b) ray trace model for pupil accessibility — to produce a coverage metric to represent retinal accessibility to damage from lasers. Data were collected from nine subjects and a computer model was used to determine the proportion of incident rays that could access the pupil. Overall, the combined result provides an efficient methodology to assist when design trade-offs are required in the evaluation of protective spectacles. This technique can be used to quantify the amount of coverage and assign a conservative level of risk to the areas of the visual field that remain uncovered.
