LASIK works well, according to long-term study of highly myopic patients
Laser surgery to correct vision problems has been in use since the early 1990s. Photorefractive Keratotomy (PRK) is typically used to correct low to moderate myopia, while laser in-situ keratomileusis (LASIK) is preferred for high myopia corrections. view more (2007-12-28)
Violent Video Games Can Improve Vision
Video killed the radio star, the old song goes - but violent video games, a new Tel Aviv University study finds, can also improve the real-world vision of teens who play them. view more (2009-04-08)
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)
Turning huge data volumes into images
The first thing that a CAT scan of the human heart produces is simply data. Together with graphics hardware, the image processing software then constructs a picture that can be displayed on the computer. It's only natural that medical personnel, and even materials researchers, desire the most detailed images possible. But this always means... view more... (2003-02-20)
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)
Why Do Autumn Leaves Bother to Turn Red?
Soils may dictate the array of fall colors as much as the trees rooted in them, according to a forest survey out of North Carolina. view more (2007-10-26)
Eye researchers develop new 3-D monitor vision test for children
A new random-dot stereotest using a 3D display and infrared oculography has been found to objectively assess stereopsis in children older than three years according to an article published in the November 2006 issue of Investigative Ophthalmology & Visual Science (IOVS). view more (2006-10-26)
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...

Choosing the wood using artificial vision
Amongst the TR+D projects financed by the Basque Government INTEK programme, the IT Department at CIDEMCO, in conjunction with the CEIT Centre of Technology, the CVC company, and furniture manufacturers BIOK, XEY and DANONA, have finished the final phase of the development of an artificial vision system for the formulation of colorants for the... view more...

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)

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.

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)
How the brain weaves a memory
Memories of events comprise many components-including sights, sounds, smells, and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus. view more (2006-11-09)
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)
