The restricted visual fields available to SCUBA divers were examined by means of an under-water perimetry apparatus. Measurements were obtained for three standard partial masks (covering only the eyes and nose), one atypical “wrap-round” partial mask, and one full-face mask. Data are presented along with some consideration of the interactions between mask design and visual field, and a brief resumé of procedural variables affecting human factors experimentation underwater.

Vision through Various Scuba Facemasks
TLDR
The visual performance using five commercially avaible facemasks was compared and there were significant differences among the masks for every visual process tested.
Adaptation of divers to curvature distortion under water.

TLDR
The apparent curvature in depth of a straight line was measured for seven divers in air and water before and after a half-hour dive in the sea, suggesting that the experienced divers had acquired a ‘ situation-contingent ’ visual response.
Underwater Distance Distortion within the Manual Work Space
An experiment was conducted to measure apparent distance of a target within arm's length above water and under water. Eight experienced divers and eight novice divers wearing facemasks indicated
Man in the Ocean Environment: Psychophysiological Factors
TLDR
In an underwater environment certain changes take place in the visual process due to the change of the visual medium from air to water, relevant to the effective engineering of underwater tools and equipment and the orientation of the underwater worker who must perform in a strange environment.
Perceptual Narrowing in Novice Divers1
TLDR
During diving, a distinct subgroup of the dual-task subjects exhibited markedly increased response times to the peripheral light while maintaining near constant performance on the central tasks, and appeared more closely related to diving risk than to other environmental factors.
Diver Performance and the Effects of Cold
TLDR
The capability of divers was tested by a test battery composed of tests of tactile sensitivity, grip strength, manual dexterity, tracking, assembly of a structure by groups, mental arithmetic, symbol processing, simple problem solving and memory, and in terms of a hypothesis that immersion in cold water serves to distract the diver.

Diving into the abyss: scenography for contemporary aquatic theatres
Confronting the dominance of two-dimensional computer images that keep us distant from what we see, the commercial entertainment industry continues to search for ways to involve the audience in the
Anxiety and Panic in Recreational Scuba Divers
TLDR
There is evidence that individuals who are characterised by elevated levels of trait anxiety are more likely to have greater state anxiety responses when exposed to a stressor, and hence, this sub-group of the diving population is at an increased level of risk.

TLDR
To restore normal vision under water, masks or goggles, which replace the air at the corneal surface, and lenses containing air cells have been used, and diving masks have almost completely replaced goggles since masks give a better field of vision.
