The Science Behind the Technology
At blinkcns, our mission is to spearhead advancements in neurological health through innovation. Leveraging the concept of blink reflex technology, we have devised EyeStat, a revolutionary tool that provides clinicians, athletic trainers, physicians, and medical researchers with objective data for neurological conditions.
The Evolution
1st Generation Device
The Gen 1 blink reflexometer was invented at the Medical University of South Carolina (MUSC). It consisted of a mask, a housing unit, a stimulation system, a camera, an external controller and processor, and a user interface. Tubing connected to the left end of the housing unit delivers a puff of compressed air to the subject’s eyes.
2nd Generation Device
Same as Gen1 but with 3D printed housing unit and mask.
3rd Generation Device
FDA-cleared, commerical version of the Blink Reflexometer, called EyeStat. Portable, 5.5lbs, operated on a tripod.
4th Generation Device
Reengineered, smaller, and lighter version
of EyeStat with a head strap.
5th Generation Device
The computer, cameras, lights, fans and more were removed from the Gen4, and replaced with a spot for a mobile device. The mobile device will run the blinkcns app where a test can be initiated. The app runs all image capturing, processing, etc.

Patient Assessment
Insert mobile device into EyeStat5 with the camera lens facing inward and oriented toward the top.
Mobile device will insert to the point where its camera lens is centered within the EyeStat5.
Launch EyeStat5 software and confirm the patient’s eyes are centered on mobile device screen.
Press the record button to initiate
the scan.
• Non-invasive
• 30-second test
• 7,200 high-resolution pictures of the eye.
The post-scan screen provides options to review, save, delete, or rescan.
The Blink Reflex
The blink reflex involves two cranial nerves, the trigeminal (V) and facial (VII) nerves, routing through the medulla and pons in the brainstem.
The trigeminal nerve, when stimulated, sends a message directly to the brainstem. The message is translated, and the brain’s response is transmitted back through the brain to the facial nerve (and, in turn, to the muscles controlling the eyelids). The result is the blink reflex.
Blinking is a reflexive nervous system response.
​
Damage (trauma or disease) to the brain will cause a change in the corneal blink reflex.
The eye blink reflex is a biomarker of brain function used in the diagnosis and assessment or neurological disease and conditions.
