Human eye inspires advance in computer vision from Boston College researchers
Inspired by the behavior of the human eye, Boston College computer scientists have developed a technique that lets computers see objects as fleeting as a butterfly or tropical fish with nearly double the accuracy and 10 times the speed of earlier methods. view more (2009-06-18)
Omega-3 fatty acids appear to impact AMD progression
Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken. view more (2009-06-18)
New Study Indicates Radiologists Need Standards to Ensure Optimal Visual Accuracy
Radiologists, like professional pilots for example, depend on good vision as part of their occupation. However, radiologists unlike pilots are not required to undergo regular vision testing. view more (2009-06-10)
Vision impairment costs billions lost in productivity
Corrected vision impairment could prevent billions of dollars in lost productivity annually. view more (2009-06-03)
Male or female? Coloring provides gender cues
Our brain is wired to identify gender based on facial cues and coloring, according to a new study published in the Journal of Vision. view more (2009-05-28)
Small evolutionary shifts make big impacts -- like developing night vision, researchers find
In the developing fetus, cell growth follows a very specific schedule. In the eye's retina, for example, cones -- which help distinguish color during the day -- develop before the more light-sensitive rods -- which are needed for night vision. view more (2009-05-21)
New insight into primate eye evolution
Researchers comparing the fetal development of the eye of the owl monkey with that of the capuchin monkey have found that only a minor difference in the timing of cell proliferation can explain the multiple anatomical differences in the two kinds of eyes. view more (2009-05-19)
Protein-protein interaction explains vision loss in genetic diseases
The mystery of genetic disease is only partially solved with the identification of a mutated gene. Often, the pattern of disease - the features or disorders associated with it - vary in type and severity among those who are affected. Scientists, physicians and patients all ask why. view more (2009-05-11)
'Gecko vision': Key to the multifocal contact lens of the future?
Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses. view more (2009-05-08)
UAB Tear Research Focused on Contact Lens Risks, Benefit
Contact lenses are great for sight, but do they have an impact on general eye health? Researchers at the University of Alabama at Birmingham (UAB) School of Optometry are working to answer that question by analyzing tears. view more (2009-05-07)
Consumers more likely to identify healthy food using traffic light nutrition labels
Consumers are five times more likely to identify healthy food when they see colour-coded traffic light nutrition labels than when labels present the information numerically by showing what percentage of the recommended daily nutrient intake each portion provides, new research finds. view more (2009-05-07)
Early brain activity sheds new light on the neural basis of reading
Most people are expert readers, but it is something of an enigma that our brain can achieve expertise in such a recent cultural invention, which lies at the interface between vision and language. view more (2009-04-28)
Solar wind tans young asteroids
A new study published in Nature this week reveals that asteroid surfaces age and redden much faster than previously thought -- in less than a million years, the blink of an eye for an asteroid. This study has finally confirmed that the solar wind is the most likely cause of very rapid space weathering in asteroids. This fundamental result will... view more... (2009-04-23)
Researchers identify gene associated with muscular dystrophy-related vision problems
Skeletal muscle disease and vision deficits might seem unrelated, but a frog model of muscular dystrophy shows it is not such a leap. view more (2009-04-21)
When every photon counts
The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision). They have to perceive light which is less than a millionth of the intensity of daylight. view more (2009-04-17)
Study reports success in treating a rare retinal disorder
Patients with a rare, blinding eye disease saw their vision improve after treatment with drugs to suppress their immune systems, according to researchers at the University of Michigan Kellogg Eye Center. view more (2009-04-15)
Erectile dysfunction treatments do not appear to damage vision over 6 months
Two medications used to treat erectile dysfunction in men (tadalafil and sildenafil) do not appear to have visual side effects when taken daily for six months, despite concerns about eye-related complications. view more (2009-04-14)

Caltech researchers train computers to analyze fruit-fly behavior
Scientists at the California Institute of Technology (Caltech) have trained computers to automatically analyze aggression and courtship in fruit flies, opening the way for researchers to perform large-scale, high-throughput screens for genes that control these innate behaviors. view more (2009-04-09)
Stem cell therapy makes cloudy corneas clear, according to Pitt researchers
Stem cells collected from human corneas restore transparency and don't trigger a rejection response when injected into eyes that are scarred and hazy, according to experiments conducted in mice by researchers at the University of Pittsburgh School of Medicine. view more (2009-04-09)
