Physicists have found that intense visual input forces the brain into a brief moment of chaos, but the visual cortex spontaneously returns the brain to its optimal function.
Researchers have discovered a thick band of microtubules in certain neurons in the retina that they believe acts as a transport road for mitochondria that help provide energy required for visual processing.
Environmental factors like pool and ocean water seem harmless, but they can actually affect eye health. UAB experts break down how to stay safe this season.
More Americans are using soft contact lenses—especially daily disposable lenses—and taking advantage of new designs targeting vision problems that were difficult to correct with previous contact lenses, reports the July issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
Our brains track moving objects by applying one of the algorithms your phone’s GPS uses, according to researchers at the University of Rochester. This same algorithm also explains why we are fooled by several motion-related optical illusions, including the sudden “break” of baseball’s well known “curveball illusion.”
A new experiment shows that auditory melodies can enhance a musician's visual awareness of written music, particularly when the two match.
When cataracts encroach on the eyes, the only effective remedy is to surgically replace the eyes' lenses with synthetic substitutes. But what if scientists found a way to delay or prevent cataracts from forming in the first place? Researchers at the University of Delaware may have found such an opportunity by identifying the prime suspects in the formation of cataracts – deficiency of two genes that encode regulatory proteins.
Studying mice, scientists at Washington University School of Medicine in St. Louis have identified a neural circuit in the retina that carries signals enabling the eye to detect movement. The finding could help in efforts to build artificial retinas for people who have suffered vision loss.
A miniature version of the University of Iowa’s advanced driving simulator will participate in a clinical trial later this year to assess a patient’s driving ability after cataract surgery.
A series of immersive virtual reality experiments has confirmed that the human brain’s internal navigation system works in the same fashion as the grid cell system recently found in other mammals.
To observe Cataract Awareness Month in June, ophthalmologists from New York Eye and Ear Infirmary of Mount Sinai (NYEE) and The Mount Sinai Hospital (MSH) – both part of the Mount Sinai Health System – are offering prevention tips and raising awareness of options for early detection and effective treatment.

A rare eye disorder marked by color blindness, light sensitivity, and other vision problems can result from a newly discovered gene mutation identified by an international research team, including scientists from Columbia University Medical Center (CUMC). The findings, which were published today in the online edition of Nature Genetics, could lead to new, targeted treatments for this form of color blindness.
People with achromatopsia, an inherited eye disorder, see the world literally in black and white. Worse yet, their extreme sensitivity to light makes them nearly blind in bright sunlight. Now, researchers at University of California, San Diego School of Medicine and Shiley Eye Institute at UC San Diego Health System have identified a previously unknown gene mutation that underlies this disorder.
New York Eye and Ear Infirmary of Mount Sinai (NYEE) joins with the International Orthoptic Association (IOA) to observe June 1st as World Orthoptics Day.
Using high-precision genetic tests to differentiate the thousands of bacteria that make up the human microbiome, researchers at NYU Langone Medical Center suggest that they have found a possible — and potentially surprising — root cause of the increased frequency of certain eye infections among contact lens wearers.
Much like the automatic focus of a camera, our eyes and brains must constantly recalibrate so that we can get a clear view of the changing—and always moving—world around us. Two studies funded by the National Eye Institute (NEI) show how the circuitry for this eye-brain coordination is assembled during early embryonic development.

Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
Driving down a dimly lit road at midnight can tax even those with 20/20 vision, but according to a recent UC Irvine study, the brain processes the experience no differently than if it were noon. The same study also reveals how quickly the brain adapts to vision loss, contradicting earlier research and opening the door to novel treatments.
