The human retina contains some 100 million photoreceptor cells. When these are stimulated with light, they communicate that information to the brain and we perceive light. Researchers have now ...

WEST LAFAYETTE, Ind. – Capturing objective data in about five seconds that can aid concussion diagnoses through an iPhone, the Reflex PLR Analyzer, an industry-disruptive diagnostic tool for traumatic ...

New research points to an easily measured eye response to light as a potentially useful way of diagnosing autism in very young children. Further testing is currently underway in a large cohort of ...

In the eye, the pupil is the opening in the middle of the iris. It appears black because most of the light entering it is absorbed by the tissues inside the eye. The shape of the pupil varies between ...

The creation of a bionic eye that mimics the widening and shrinking of the pupil may bring us one step closer towards helping people with certain visual impairments. Light enters the eye via the pupil ...

Measuring how the eyes' pupils change in response to light - known as the pupillary light reflex - could potentially be used to screen for autism in young children, according to a study conducted at ...

WEST LAFAYETTE, Ind. – Evaluating concussion patients for recovery and measuring compounding injuries can be done as simply as recording a video with a smartphone. Reflex, a smartphone application ...

Experimenting with mice, neuroscientists report new evidence that the eye's iris in many lower mammals directly senses light and causes the pupil to constrict without involving the brain.

An artificial vision sensor inspired by the human pupil adapts automatically to light, maintaining clear perception from darkness to glare and sharply improving recognition accuracy in machine ...
