Eyes - Vision



All About the Eye and Vision - Diseases - Wikipedia

An eye is an organ of vision that detects light. Different kinds of light-sensitive organs are found in a variety of organisms. The simplest eyes do nothing but detect whether the surroundings are light or dark, while more complex eyes can distinguish shapes and colors. Many animals, including some mammals, birds, reptiles and fish, have two eyes which may be placed on the same plane to be interpreted as a single three-dimensional "image" (binocular vision), as in humans; or on different planes producing two separate "images" (monocular vision), such as in rabbits and chameleons.

New-age prosthetic technique enables blind mice to see   PhysOrg - December 23, 2011
A recent TEDMED talk has scientists interested in a presenterŐs novel techniques to help the blind. A device with two parts, encoder and transducer, can do the job. Sheila Nirenberg, a neuroscientist and professor at Weill Medical College of Cornell University, recently discussed the results of her work at TEDMED on how the brain takes external information and encodes it in patterns of electrical activity. She set out to describe what her team found in exploring how the retina communicates with the brain.

Can humans sense the Earth's magnetism?   PhysOrg - June 21, 2011
For migratory birds and sea turtles, the ability to sense the Earth's magnetic field is crucial to navigating the long-distance voyages these animals undertake during migration. Humans, however, are widely assumed not to have an innate magnetic sense.

Humans May Have 'Magnetic' Sixth Sense   Live Science - June 21, 2011
Humans may have a sixth sense after all, suggests a new study finding that a protein in the human retina, when placed into fruit flies, has the ability to detect magnetic fields.

Human eye protein senses Earth's magnetism   BBC - June 21, 2011
A light-sensitive protein in the human eye has been shown to act as a "compass" in a magnetic field, when it is present in flies' eyes.

Historic First Images of Rod Photoreceptors in the Living Human Eye   Science Daily - June 10, 2011
Scientists have just reported that the tiny light-sensing cells known as rods have been clearly and directly imaged in the living eye for the first time. Using adaptive optics (AO), the same technology astronomers use to study distant stars and galaxies, scientists can see through the murky distortion of the outer eye, revealing the eye's cellular structure with unprecedented detail. This innovation, described in two papers in the Optical Society's (OSA) open access journal Biomedical Optics Express, will help doctors diagnose degenerative eye disorders sooner, leading to quicker intervention and more effective treatments.

Study reveals how the eye is formed   PhysOrg - April 6, 2011
These findings significantly enhance understanding of how the different components of the eye are organised into a functional organ, and therefore reveal clues as to the possible causes of congenital malformations that lead to life-long visual impairment.
