Photic sneeze reflex is a condition triggered by exposure to bright light. Around 35% of the population has this reflex. Sneezing is a natural response that removes irritants from your nose.

Researchers have now discovered that when light impinges on the photoreceptor-free blind spot alone the pupillary reflex does not occur, but the pupillary reflex is enhanced in response to bright ...

This new research looks at a behavior in the eye called pupillary light reflex. This is the simple reflex our pupils make in response to surrounding light levels. In the past, pupillary light ...

My light-induced sneezes are caused by a seemingly harmless disorder called “photic sneeze reflex.” The Greek philosopher Aristotle referenced the phenomenon during the fourth century B.C ...

The study entitled "Multisensory signals inhibit pupillary light reflex: Evidence from pupil oscillation" has been published in Psychophysiology. More information: Xiangyong Yuan et al ...

A new study showed that NeurOptics Pupillometers reliably measure the presence and quality of the pupillary light reflex after cardiac arrest and during resuscitation, producing readings that ...

Reflex, a smartphone application developed by Purdue Foundry-affiliated startup brightlamp, works like a pupillometer. It takes a digital video recording of an individual's eye to measure a response ...

The so-called pupillary light reflex compensates for changes in light levels by adjusting the pupil’s size, allowing people to see in high resolution, while protecting the retina from bright light.

Using the latency component of the pupillary light reflex, they were able to distinguish subjects with or without autism with 89.6% success. When constriction amplitude was figured in, the success ...

Reflexive sneezing induced by light, and sunlight in particular, is estimated to occur in 18 to 35 percent of the population and is known as the photic sneeze reflex (PSR) or the ACHOO (autosomal ...
