Abstract:

The visual performance of divers was compared through five commercial facemasks. Measurements were made of visual fields, visual acuity, stereoacuity, hand-eye coordination, accuracy of distance estimates, and accuracy of size estimates at both near and far distances. In addition, the optical properties of the masks were measured and the susceptibility of each mask to fogging was tested. There were significant differences between the masks for every visual process tested. Some masks were superior for one purpose and inferior for another purpose.
