Dive into the research

How It Works

The RETeval device will start flashing light into the patient's eye.

The retina responds to the flashes by generating small electrical signals that travel through the facial structure to the Sensor Strip.

The Sensor Strip detects the electrical signals and compares the results to the age-adjusted reference database.
