Why do I have to subscribe for my free trial period?

We do this to ensure uninterrupted service while transferring from the free trial period to the subscription. The free trial period gives you one month free and you can cancel anytime if you wish.

Is Reflex a medical device and approved by the FDA?

Yes, Reflex is a Class I 510(k) Exempt medical device as laid out in 21 CFR 886.1700 by the FDA. This classification does not require formal approval by the FDA.

Is Reflex available on Android?

Not yet! We are actively working on an Android version and will update our audience when it is ready to go.

Why doesn’t Reflex work on my iPhone 6s or under?

The computational sophistication of Reflex makes it to where we cannot guarantee that it will record tests correctly on the iPhone 6s or below. Because of this, we restrict the devices to iPhone 7 and up.

Why does the Pupillary Light Reflex chart look incorrect?

There are many reasons that could result in a ‘failed test’. As we improve our technology we will be integrating new methods for failure mode catching and correction. The most common result is due to too much movement from the device. Try retesting with your arms anchored to a stable object. Additional problems include poor lighting conditions and the person looking away. If the problem persists then please contact us so we can help.

Why is Reflex giving me an error for the processed video?

There are a few reasons that this could occur. 1) You are too far away from the individual for our system to reliably find the iris for processing or 2) The test conditions that are being run are causing Reflex to not process enough frames to make the data useful. We check every video for quality of measurement to ensure the best data is being delivered.

Why are there zero values in the data time series?

If Reflex can process most of the video, without significant error, then it will deliver results back that include portions that were not able to be processed by Reflex. Sometimes this includes leading, trailing, or intermediary values. Typically, for intermediary values, Reflex can interpolate to determine a curve so this does not occur frequently. Leading and trailing zeros indicate extrapolation is needed which Reflex will never do.

What happens if the test subject blinks?

Typically this does not present a large issue to the test. You will likely see a small rise in pupil diameter due to the quick blocking of incoming light to the pupil. The resulting curve should be okay depending on the duration the eye is closed. To be certain, you can retest the same eye without the subject blinking.

Can Reflex integrate with EMR?

Not yet, but we are actively working with engineers for full EMR integration support.

Why is there a barcode scanner in Reflex?

Many medical record systems use barcode technology to rapidly identify the individual it is corresponding to. We integrated this feature to make inputing the subjects medical record number (MRN) or identification number as easy as possible. If you are unsure that the barcode contains correct identifying information then please use the manual identification number entry field.

Why can’t I open the secure zip file that was sent to my email from Reflex?

You may need to download a supplementary unzipping client to open the secure, encrypted, file. 7 Zip is a useful unzipping tool that will get your data ready to go.
