Study questions assumptions about human sensitivity to biological motion
Humans may not be any more sensitive in detecting biological motion compared with nonbiological motion, concludes a study recently published in Journal of Vision, an online, free-access publication of the Association for Research in Vision and Ophthalmology (ARVO). view more (2007-10-18)
Vision problems prompt older drivers to put down the keys
With 30 million drivers in the US aged 65 and over, we count on older Americans to recognize when they can no longer drive safely and decide that it's time to stay off the road. A new study finds that a decrease in vision function is a key factor in bringing about this decision. view more (2009-01-07)
Researchers within sight of a breakthrough on blindness
The discovery by a Leeds University scientist of a new blindness gene could help to save the sight of thousands of sufferers of retinal disease which affects premature babies as well as people over 60. view more (2004-11-03)
The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. view more (2007-09-05)
Limitless applications seen for micro-projector
A Finland-based company has unveiled ground-breaking optical technology allowing the manufacture of a matchbox-sized video projector. The results could be used in environments ranging from airplanes to nightclubs, living rooms to boardrooms, car dashboards to campsites. Billed as "the world's smallest colour video projector," this inexpensive... view more... (2004-06-03)
Age-related vision problems may be associated with cognitive impairment
Older patients with advanced age-related macular degeneration and reduced vision may be more likely to also have cognitive impairment, or problems with thinking, learning and memory. view more (2006-04-11)
Gold beads show previously unseen parts of the eye
A new study recently published in Journal of Vision, an online, free access publication of the Association for Research in Vision and Ophthalmology (ARVO), shows that gold beads injected into eye tissue can be used to obtain images of important structures in the orbit that cannot be seen with Magnetic Resonance Imaging (MRI) or other imaging... view more...

Why Popeye only has eyes for spinach
Eating spinach could protect your eyes from the leading cause of blindness in western society, say experts at The University of Manchester. view more (2006-09-26)
EYE DAMAGE AFTER SOLAR ECLIPSE NOT AS HIGH AS EXPECTED (p199)
Damage to the sight of those who looked directly at the sun during the eclipse of August 1999 may not be as bad as expected, reports a research letter in this week's issue of THE LANCET. Looking at the sun can cause burns to the retina. The UK Department of Health's advice at the time of the eclipse was to use an indirect method of looking at the... view more... (2001-01-18)
Cerebrospinal Fluid Restores Vision
A new method for visual impairment treatment has been discovered by researchers of the Institute of Human Brain, Russian Academy of Sciences. The patients suffering from visual impairment can be helped if a healthy donor's cerebrospinal fluid is introduced to the parent's vertebral canal - this method is called liquortransfusion. Physiologists... view more... (2004-11-01)
Vision loss more common in people with diabetes
Visual impairment appears to be more common in people with diabetes than in those without the disease, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals. view more (2008-10-14)
The First Robot Librarian Is Born At The University Jaume I
A team of researchers from the Intelligent Robotics Laboratory at the University Jaume I (UJI) in Castell'łn, Spain, has created the first automat capable of performing the tasks usually carried out by a library clerk. The robot uses speech-recognition to identify the book that is being requested, then determines its location, goes to the shelf,... view more... (2004-07-01)
New evidence that popular dietary supplement may help prevent, treat cataracts
Researchers are reporting evidence from tissue culture experiments that the popular dietary supplement carnosine may help to prevent and treat cataracts, a clouding of the lens of the eye that is a leading cause of vision loss worldwide. view more (2009-07-16)
Pioneers in field of functional genomics work toward gene therapy for vision defects
"Primates and humans have three photoreceptors and can only see four basic colors, red, green, blue and yellow," says Jay Neitz, Ph.D. "Birds, fish and reptiles have four photoreceptors, allowing them to see things we cannot. They must see an entire dimension of color, including ultraviolet, infrared and all the combinations... view more... (2006-12-12)
Machine vision can assist
Machine vision provides a unique capability for understanding human actions. Based on a passive sensing technology, it allows for the coverage of large areas with a single sensor, without need for physical contact. Professor Matti Pietik'¤inen is in charge of the machine vision research team whose aim it is to equip the environment with several... view more... (2005-04-07)
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)
Elephant shark genome sequence leads to discovery of color perception in deep-sea fish
The elephant shark, a primitive deep-sea fish that belongs to the oldest living family of jawed vertebrates, can see color much like humans can. view more (2009-03-18)
Sight can recover quickly in amblyopia
New research findings led by Thomas Krahe and Ary S. Ramoa of Virginia Commonwealth University School of Medicine offer two pieces of good news for treating children with amblyopia. view more (2005-10-20)
New 'implanted contacts' designed to fix nearsightedness
UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness. view more (2006-02-28)
Opals set to shine with new grading technology
CSIRO and a consortium of Australian Opal miners (Opal Producers Australia Limited) have unveiled the world's first automated device to grade opals using image analysis, at the 2009 National Council of Jewellery Valuers forum in Sydney. view more (2009-08-31)
