What is the EyeStat platform?
EyeStat is a quick and easy test that provides objective data about the stimulation and response to initiation of the blink reflex. Over a 20 second period of time, a patient’s reflex is induced 5 times by passing light puffs of air across the eyelashes at random intervals. EyeStat captures and records 12,000 objective data point images of the patient’s blink reflex using high-speed imaging technology. The data is then analyzed using the EyeStat proprietary software platform and algorithm. Within one minute, the results of four physiological variables of the blink reflex are shown on the EyeStat screen.
How easy to use is the EyeStat technology?
EyeStat has an intuitive user interface and is incredibly easy to use. Everything from setting up the device, logging in, to running a scan on a patient can be done by anyone and takes minimal training. Because the device is lightweight and portable, it can be operated from anywhere.
Is the device portable?
EyeStat weighs less than 5lbs and is housed in a robust, sturdy case for easy transport and use. An easy-to-assemble tripod is included with each device making testing possible from anywhere, like clinics, training rooms, sidelines, etc.
How fast is the device?
The device “puffs” 5 times at random intervals over a 20 second time period. During the test, 12,000 pictures of the blink reflex are taken which are then processed with our proprietary algorithm. Conducting the test and concluding the results take under one minute total.
What products are included in my purchase?
Each purchase includes a durable carrying case for portable use which houses EyeStat, a charger, C02 cartridges, a tripod, pulse oximeter and a quick start user manual.
What services are included in my purchase?

Blinktbi will also offload the process of uploading member data (i.e. team rosters) to a customer’s account during the initial onboarding process, along with formal training for the appropriate staff on how to operate EyeStat.
How do I get trained to use it?
All users are formally trained on how to operate EyeStat by a blinktbi sales representative. The sales representative will coordinate the logistics of training the customer and any additional team members. Click here to download the EyeStat User Manual.
How much money can this device save me?
EyeStat is very cost competitive to other options in the market. For detailed pricing information, please contact us directly at email@example.com and a blinktbi sales representative will contact you.
How do I clean it?
After every use, use isopropyl alcohol wipes (at least 70%) to clean all touch surfaces (mask, screen, power button, etc.). The camera lenses should not be touched, but in the rare event that there is reason to clean them (i.e fingerprints on the lens, dust buildup, etc.) use rubbing alcohol and a Q-tip to gently clean the glass.
Can this test be cheated or manipulated?
EyeStat uses puffs of air to stimulate the blink reflex, which is an involuntary autonomic nervous system response. Therefore, because this is based on human reflexes, it is impossible to cheat the test and manipulate results.
Is a baseline required?
Yes, EyeStat currently requires baseline.
What age is this used for?
Our current studies include patients as young as 6 years old and up to 34 years old However, EyeStat has been tested with ease on children as young as 3 years old and as old as 79 years old.
Does it matter if I am wearing contact lenses when I take the test?
Leave your contacts in. The puff of air is not intended to touch your eyeball; it simply puts a slight puff of air on your eyelashes at the outside corner of your eye, called the outer canthus, to stimulate the blink response. The camera and algorithm look at the top eyelid, so as long as it can see your eye, you will get a result. The cameras use the pupil to align itself and essentially "find" the eyelashes.
Can EyeStat be used in combination with traditional Neurocognitive tests?
Yes, EyeStat provides the diagnosing clinician with 100% objective data of the blink reflex which can be used in conjunction with neurocognitive tests, thus supporting the clinician’s informed medical decision for management of the patient.
How many people can I scan using EyeStat?
With the battery charge at 100%, EyeStat can scan approximately 75-80 people before it needs to be recharged. A new CO2 cartridge can deploy approximately 500 puffs of air which equals about 100 total scans.
Does the air puff feel like the glaucoma test machine at the eye doctor?
Not quite. It is a very light puff on the outside corner of the eye and lashes, which causes you to blink. The puff doesn’t touch the eyeball.
Are there any contraindications for use?
EyeStat is contraindicated in patients who have a documented history of seizure or other brain-related abnormalities and should not be tested unless cleared by a physician or medical professional. EyeStat testing should not be administered on patients who present with an existing-eye-problems, such as an infection, until the problem has resolved, and the patient is approved for testing by a physician or medical professional. EyeStat should not be used by a patient diagnosed with closed-angle glaucoma.
What if I flinch during the test?
The "random" nature of the puffs of air are intended to catch you off guard, thus causing a blink response. As long as your face stays up against the mask, the system can keep track of your eyelid by following the pupil while you flinch.
How do I get the results? Can I export them?
The results of four physiological variables of the blink reflex are shown on the EyeStat screen. They are also automatically uploaded to blinktbi’s secure cloud and web-portal, provided in a visual dashboard for interpretation and as a numeric value. The blinktbi Web Portal is a Medical Device Data System (MDDS) that allows for transferring, storing and displaying the data from the EyeStat device. Results can also be exported via PDF or secure data transfer to an EMR or other database through our API.
Science / Data
What is EyeStat measuring?
EyeStat measures the involuntary response of 4 physiological variables of the blink reflex: The time it takes from the moment the air touches the side of the face until the eyelid on the stimulated side begins moving; how long the eye stays closed during a blink; the number of blinks immediately after the stimulus; and the distance between the place your eyelid sits when you are simply looking forward and when it is closed.
What is the blink reflex?
The blink reflex is an involuntary reaction elicited by stimulation near the cornea of the eye. The trigeminal nerve, when stimulated, sends a message through the brain 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. EyeStat’s stimulation of the cornea of the eye is through passing a light puff across patient’s eye lashes.
What is Saccadic Eye Movement?
Saccades is defined as a quick, simultaneous movement of both eyes moving in the same direction between two or more points. Saccades can be involuntary or voluntary movement of the eye. Testing for saccades invokes a voluntary movement of the eyes, i.e. tracking a moving object such as a ball as it moves around on a screen or watching a film for a period of time.
What is the Autonomic Nervous System?
Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart, digestion, the widening or narrowing of your blood vessels, and your blink reflex.
How has EyeStat been validated?
EyeStat has been validated through a multi-center study in accordance with an approved IRB protocol. Initial EyeStat baseline assessments are obtained from consented athletes. Should a clinical diagnosis of concussion be made using the participating schools’ protocol, follow-up EyeStat scans are taken at the time of the event and thereafter at scheduled intervals during the course of the athletes symptomatic period and through his or her return-to-play period.
What research do you have?
EyeStat researchers have collected and assessed blink reflex data from more than 4,600 male and female subjects ranging from 6-to-34 years in age. Blinktbi’s growing research database of 100% objective data represents a broad cross-section of conditions and settings from youth sports, high schools, colleges and universities, professional sports teams, healthcare systems and concussion centers. To date, blinktbi has 1 published paper in Cogent Engineering Journal and 1 in IEEE, with more currently underway.

Is the device FDA cleared?
Yes, EyeStat obtained FDA clearance in December 2019. EyeStat is indicated to measure and display the mechanically induced blink reflex.
