The majority of studies on blindsight are conducted on patients who are hemianopic, i.e. blind in one-half of their visual field.Following the destruction of the left or right striate cortex, patients are asked to detect, localize, and discriminate amongst visual stimuli that are presented to their blind side, often in a forced-response or guessing situation, even though they may not ...
Blindsight is a hard science fiction novel by Canadian writer Peter Watts, published by Tor Books in 2006. It won the Seiun Award for the best translated novel [2] and was nominated for the Hugo Award for Best Novel, [3] the John W. Campbell Memorial Award for Best Science Fiction Novel, [4] and the Locus Award for Best Science Fiction Novel. [5]
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

Blindsight is being developed to enable individuals with total visual impairment due to damage to the optic nerve but with intact visual cortex to see, this is made possible by bypassing the optic nerve and directly stimulating the visual cortex to create a visual perception.
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
The question was originally posed to him by philosopher William Molyneux, whose wife was blind: [2] Suppose a man born blind, and now adult, and taught by his touch to distinguish between a cube and a sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and the other, which is the cube, which is the sphere.
[27] [4] [28] [dubious – discuss] The blind spot is at about 15.5° in the outside direction (e.g. in the left visual field for the left eye). [29] The grain of a photographic mosaic has just as limited resolving power as the "grain" of the retinal mosaic. To see detail, two sets of receptors must be intervened by a middle set.
Sir John recognised the potential of these camps to deliver the world’s largest sight restoring programme. In the late 1960s, an experiment was launched in Katsina, Nigeria to determine whether blind children could be educated in local schools with the assistance of itinerant teachers. The scheme proved highly successful and was the ...
