Tellurium nanowire retinal nanoprosthesis improves vision in models of blindness.

Science
Present vision restoration technologies have substantial constraints that limit their application in the clinical setting. In this work, we fabricated a subretinal nanoprosthesis using tellurium nanowire networks (TeNWNs) that converts light of both the ...

Occupational testing of near vision

Ophthalmic and Physiological Optics, 1994
The quality of near vision depends on distance visual acuity, accommodation capability and near vision correction, and cannot therefore be expressed in acuity values. Most near vision tests do not recognize this, and the lack in standardization should lie mainly attributed to this fundamental shortcoming.

Altered vision near the hands

Cognition, 2008
The present study explored the manner in which hand position may affect visual processing. We studied three classic visual attention tasks (visual search, inhibition of return, and attentional blink) during which the participants held their hands either near the stimulus display, or far from the display. Remarkably, the hands altered visual processing:
