A hand moves forward, but is it a friendly gesture or one meant to do harm? In an instant, we respond -- either extending our arm forward to shake hands or raising it higher to protect our face. But what are the subtle cues that allow us to interpret such movement so we can properly respond to others?

Sophisticated mathematical modeling methods and a “CatCam” that captures feline-centric video of a forest are two elements of a new effort to explain how the brain’s visual circuitry processes real scenes. The new model of the neural responses of a major visual-processing brain region promises to significantly advance understanding of vision.

The standard eye chart only covers letters and numbers, but athletes need above average vision to track balls hurtling toward them at alarming speeds. To test those special skills, a University of Houston optometrist has founded the Sports Vision Performance Center, a facility where athletes perform while a strobe light is flashing, play tag with a board of lights and engage in other activities designed to improve their visual abilities.

Since the first pair of contacts were launched onto the market research has come a long way. Now contact lenses are not only expected to be able to correct visual defects but also generate qualities to the eye that almost seem super human.

Exhibition of Diaton tonometer to the members of American Society of Cataract and Refractive Surgery (ASCRS) presents a great opportunity for BiCOM to display the uniqueness of the trans-palpebral and tras-scleral Diaton tonometry – tonometery through the Eyelid.

Hybridizing blind cave fish from different cave populations can partially restore the vision of their offspring, biologists at New York University have found. The study suggests that genetic engineering can override, at least in part, half a million years of evolutionary change in one generation.

Vase or face? When presented with the well known optical illusion in which we see either a vase or the faces of two people, what we observe depends on the patterns of neural activity going on in our brains.

AMO's Advanced CustomVue™ LASIK with the IntraLase® Method Proves Ready for the Rigors of Space Travel

Children with amblyopia (commonly known as lazy eye) need only wear an eye patch for three to four hours a day for 12 weeks to improve vision, say researchers in a study published on bmj.com today.

New evidence from the University of Southern California suggests that there may be dedicated cells in the retina that help compile small bits of information in order to recognize objects. The research was conducted by Ernest Greene, professor of psychology in the area of brain and cognitive sciences at USC. The study is published in the Public Library of Science journal, PLoS ONE.

The amount of the discount may be less important than the numerical value of the farthest right digit, explains a new study from the Journal of Consumer Research.

Two papers to be published in the Early Edition online of the Proceedings of the National Academy of Sciences (PNAS) the week of July 30-August 3, 2007 report findings that demonstrate that neuroprotectin D1 (NPD1) protects against damage to retinal pigment epithelial (RPE) cells and identifies an important trigger for its production and novel molecular mechanisms that support vision.
