"The human eye functions best at twilight, when it can open fully and allow us to feel, as well as see, with our eyes," he said.
These patients' eyes functioned normally, but they did not perceive much of what was in their field of vision.
Moreover, reductions in the dark-adapted response were not progressive between 2 and 10 months, as reported here for AE3−/− mice, suggesting a functional linked between AE3 and CAXIV in the normal eye function.

Early recognition and treatment may preserve eye function.
Detached retinas, angle closure glaucoma, macular degeneration, and other breakdowns of eye function all fall within this category (see Novella 2008 for a review).
These representations, after all, are not available for further processing (such as by some mind's eye function) within the computer.
(Of course, the model does not show that there is no undischarged homunculus in unimplemented parts of the theory, such as the mind's eye function, which is where we would most likely expect him to be lurking).
Kosslyn & Shwartz (1977, 1978) developed a computer simulation model of key parts of Kosslyn's theory (not including the mind's eye function), and its instantiation of the surface representation, the model for the mental image itself, is revealing.
Their long-term health effects, and even the significance of short-term changes in eye function, are unknown, he added.
