Changes in sensitivity of the dark-adapted eye during concurrent light adaptation of the other eye

Visual Neuroscience, 1992
AbstractThresholds for detection of light by a dark-adapted test eye were measured while the other, non-test eye was either similarly dark adapted or while it was exposed to an intense red adapting field. An interocular effect that depends on the retinal location of the test was found: compared to the threshold during binocular dark adaptation ...

THE SIGNIFICANCE OF EYE MOVEMENTS IN ADAPTATION TO LIGHT

Optometry and Vision Science, 1971
Baker's hypothesis that the state of adaptation in a non‐uniformly illuminated field is determined by spatial summation was tested. Measurements of eye movement following adaptation to a non‐uniform field and the presentation of a test target were recorded.

Immune privilege in the eye: An evolutionary adaptation

Developmental & Comparative Immunology, 1994
The purpose of this study was to determine whether immune privilege exists in the eye of goldfish and to explore from an evolutionary point of view the relationship between the immunological and neurobiological microenvironments in the eye. Neural retinal or scale allografts and autografts were implanted into the vitreous cavity or the anterior chamber

Eye position effects in saccadic adaptation

Journal of Neurophysiology, 2011
Saccades are used by the visual system to explore visual space with the high accuracy of the fovea. The visual error after the saccade is used to adapt the control of subsequent eye movements of the same amplitude and direction in order to keep saccades accurate. Saccadic adaptation is thus specific to saccade amplitude and direction.

Adaptive Coordination and Alignment of Eye and Hand

Journal of Motor Behavior, 1993
Under spatial misalignment of eye and hand induced by laterally displacing prisms (11.4 degrees in the rightward direction), subjects pointed 60 times (once every 3 s) at a visually implicit target (straight ahead of nose, Experiment 1) or a visually explicit target (an objectively straight-ahead target, Experiment 2).

Adaptive Optics for the Human Eye

Adaptive Optics, 1996
Aberrations limit the optical quality of the normal human eye, particularly when the pupil is large. These aberrations reduce the eye's contrast sensitivity to high spatial frequencies in the visual environment. They also limit the resolution of cameras designed to image the living human retina, a critical tool in the diagnosis and treatment of retinal

Adapting Gameplay to Eye Movements - An Exploration with TETRIS

Extended Abstracts of the Annual Symposium on Computer-Human Interaction in Play Companion Extended Abstracts, 2019
Gameplay experience is shaped by players’ expectations towards the game and how game features are presented to them. We created two modified versions of the classic TETRIS game: one that adapts game difficulty based on players’ performance and one that additionally adapts to players’ eye movements.

Toward an adaptive model of the human eye

Journal of the Optical Society of America, 1980
A model of the human eye is presented with the crystalline lens treated as having a gradient-index structure. By defining an accommodation index I ranging from 0 (unaccommodated) to 1 (accommodated), the optical parameters of the eye in various states of accommodation may be found. The results are in agreement with experimental values.

Adapting The Bluest Eye for the Stage

African American Review, 2012
Lydia Diamond's theatrical adaptation of Toni Morrison's novel, The Bluest Eye, opens with Pecola Breedlove, the story's eleven-year-old protagonist, standing at center stage. She holds a book and reads aloud from a "Dick and Jane"-style early childhood reader: "Here is the house. It is green and white. It has a red door. It is very pretty" (9). As she

Electrical Responses of the Light-Adapted Eye*

Journal of the Optical Society of America, 1953
Recordings of the human electroretinogram (an electrical response to light originating in the retina) are made while the eye is maintained at any one of three different levels of light adaptation. Conventional recording techniques and procedures are used.
