Most cameras have an auto-stabilization feature to compensate for movement during - and our eyes do also.
But in order for that imperceptible reflex that prevents our vision from blurring when we move to do its job, wirelike projections - axons - of specialized nerve cells must find their way from the retina to the correct part of the brain during embryonic development.
How those axons find their way through the brain's maze of neurons to make the right connection could lead to new ways to treat eye movement disorders.
3,000 children were treated in U.S. emergency departments in 2012 for eye injuries related to paintball guns, airsoft guns, BB guns and pellet guns - but the big increase was in airsoft guns. Paintball injuries have remained minor (0.4 per million children) and for over a decade BB gun manufacturers have restricted sales and marketing to minors, so there are not many "You'll shoot your eye out" moments due to those.
Investigators from the Stanford University School of Medicine found that the rates for eye injuries from non-bullet guns increased by 511% between 2010 and 2012, reaching 8.4 per million children and the rise was almost exclusively due to air gun related injuries, which parallels their growth in popularity.
Researchers have solved a genetic mystery that has afflicted three unrelated families, and possibly others, for generations: The genetic basis for a variety of congenital eye malformations, including the complete absence of eyes.
Phones like the Samsung Galaxy can use facial recognition rather than typing in a security code. The problem is you will end up taking twice as long quite often, because the facial recognition will fail and you type in a PIN anyway. The system is good at rejecting impostors - and also the owner.
What might help is 'morphing' together several photos for the software to analyze, so that users store an 'averaged' picture of themselves.
If you see a chicken, you know that's a chicken. If you see a cartoon of a chicken, you know that's a chicken.
But can you draw a chicken from memory?
Most people cannot draw anything that looks anything like a chicken, but is it because branding is not quality, our memories are poor, or we lose something between brains and fingers? What about something simpler and in the daily lives of Apple users more than chickens like the Apple logo? Can they draw it from memory? Probably not, as it turns out.
Is Myopia the new Rickets? A new study compares the history of school myopia with the bone disease rickets. During the 17th century, rickets was common among children in England and then reached epidemic levels through northern Europe and North America. In some cities, 80 percent of children were affected.
The remedy proved elusive until the 1920s, when scientists discovered that a lack of sunlight, resulting in vitamin D deficiency, was the cause of rickets.
Why did the earliest side-scrolling games go left to right? From the 1980s on, they seemed to do that. And in the western world people write left to right. That is enough for psychologist Dr. Peter Walker of Lancaster University to speculate that there may be a fundamental bias in the way people prefer to see moving items depicted in pictures.
Did video game developers in the early 1980s obey an evolutionary mandate in designing games? An analysis of thousands of items in Google Images led Walker to believe there is widespread evidence for such a left-to-right bias and that could a possible fundamental bias for visual motion. And it may be evidenced thousands of years ago also.
The human eye is optimized to have good color vision at day and high sensitivity at night.
But until recently it seemed as if the cells in the retina were wired the wrong way round, with light traveling through a mass of neurons before it reaches the light-detecting rod and cone cells.
New research presented at a meeting of the American Physical Society has uncovered a remarkable vision-enhancing function for this puzzling structure.
We have two eyes and each differ in their optical properties - you can easily tell by placing a hand over each and seeing the difference.
As a result of the fits and starts and do-overs in evolution that got us eyes, our vision system results in a blur projected in each retina and then the visual system calibrates itself to give us a clear picture. In the past, researchers had people where glasses where images were upside down. Eventually, our brains compensated and the images were correct - until people took off the glasses.
A dress that seems to be different colors to different people has all the Internet intrigued - and that's a good thing. It's a good way to understand science and psychology.
There are two hypotheses as to why people see dramatically different things; one is that our brains are constantly being bombarded by information and so we end up making a lot of assumptions and interpretations based on parameters. If you are looking up close at something and infer a blue background, you see the dress differently than people who assume it has an artificial light background, like yellow.
