Lens Combines Vision Of Humans And Insects To Focus Wide-Angle Views
2013-09-19 07:22:18

The Ohio State University Multi-Part Lens Expands, Contracts to Change Focus A lens invented at The Ohio State University combines the focusing ability of a human eye with the wide-angle view of an insect eye to capture images with depth. The results could be smartphones that rival the photo quality of digital cameras, and surgical imaging that enables doctors to see inside the human body like never before. Engineers described the patent-pending lens in the Technical Digest of the...

Rat's Move Their Eyes In Opposite Directions When Running For Unique View
2013-05-28 14:17:27

Lee Rannals for redOrbit.com — Your Universe Online Max Planck Institute (MPG) scientists have found that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running. This gives the rats a unique perspective on the world around them. The team discovered that each rat eye moves in a different direction, depending on the change in the animals' head position. They analyzed both eyes and found that one of the eye movements exclude the...

Optical media changes with age, but neural mechanisms keep color perception constant Cone receptors in the human eye lose their color sensitivity with age, but our subjective experience of color remains largely unchanged over the years. This ability to compensate for age-related changes in color perception rests in higher levels of the visual system, according to research published May 8 in the open access journal PLOS ONE by Sophie Wuerger from the University of Liverpool, UK. The...

(Ivanhoe Newswire) - A new technology might allow people who have almost completely lost the ability to move their arms or legs to write, by using their eyes. The eye-writing technology tricks the neuromuscular machinery into doing something that is usually impossible: to voluntarily produce smooth eye movements in arbitrary directions. Jean Lorenceau of Université Pierre et Marie Curie-Paris, was quoted as saying, "Contrary to the current belief, we show that one can gain...

Women Have Bigger Pupils Than Men

From an anatomical point of view, a normal, non-pathological eye is known as an emmetropic eye, and has been studied very little until now in comparison with myopic and hypermetropic eyes. The results show that healthy emmetropic women have a wider pupil diameter than men. SINC Normal, non-pathological emmetropic eyes are the most common type amongst the population (43.2%), with a percentage that swings between 60.6% in children from three to eight years and 29% in those older than 66....

Adaptive optics technology likely to spur sight-saving interventions, usher in new era of eye disease research, diagnosis and treatment Scientists today 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...

In a major breakthrough in the field of regenerative medicine, scientists have for the first time created a part of the eye critical for vision using animal stem cells, according to a study published Wednesday in the journal Nature. The research could pave the way to new treatments for blindness and human eye diseases, and experts say it may even be possible to one day restore vision with transplanted retinas generated from a patient's own stem cells. The researchers, led by Yoshiki Sasai of...

Seahorses are helping scientists gain new understanding about how detailed vision develops "“ in research which may open a way to restore sight in people with age-related blinding diseases. Researchers at the Vision Centre have found that the seahorses' eyes share similarities with the human eye, leading to the possibility of imitating the development of the seahorse's fovea to regenerate this vital region of the eye in people with impaired vision. "The fovea is the tiny pit at the back...

NORTH CHICAGO, Ill., Nov. 30 /PRNewswire/ -- Using a high-output camera to film the back of the human eye, for the first time researchers have shown that a resveratrol-based (rez-vair-ah-trawl) nutriceutical matrix can effectively remove cellular debris from the human eye that accumulates with advancing age and correlated this with significant improvement in visual acuity and night vision in an 80-year old man. Resveratrol is widely known as a red wine molecule. To view the Multimedia News...

Zonules of Zinn
2012-07-01 19:12:34

The Zonules of Zinn, also known as Zinn’s membrane and ciliary zonule, is a ring of fibrous strands connecting the ciliary body with the crystalline lens of the eye. The zonule of Zinn is split into two layers: a thin layer, which lines with the hyaloid fossa, and a thick layer, which is a collection of zonular fibers. Together, these fibers are known as the suspensory ligament of the lens. When color granules are displaced from the Zonules of Zinn, by friction against the lens, the...
