A proposed increase in retinal field-of-view may lead to spatial shifts in images (1003.4868v1)

Abstract: Visual information determines majority of our spatial behavior. The eye projects a 2-D image of the world on the retina. We demonstrate that when a monocular-like imaging system operates entirely with optically dense fluids, an increase in field-of-view (FOV) is observed compared to an experimental condition, where the ocular medium is optically neutral. Resulting spatial shifts in the retinal image towards the fovea complement the photoreceptor distribution pattern, incidentally revealing a new role for ocular fluids in the image space. Possible effects on the perceived egocentric object location are discussed.
