Abstract
There is disclosed a method and system for retinal stimulation and retinal signal data collection. The system comprises a housing. The housing supports one or more light sources that are configured to expose a retina of an eye of an individual to a flash of light. The housing supports a spectrometer that is configured to record a light spectrum and an intensity of the flash of light. The housing supports a camera configured to capture image data of the eye while exposed to the flash of light.

1-20. (canceled)
A system for collecting retinal signal data, the system comprising:
- one or more light sources configured to expose a retina of an eye of an individual to flashes of light;
- a spectrometer configured to record a light spectrum and an intensity of the flashes of light, wherein the system is configured to collect electrical signals produced by the retina of the individual in response to the flashes of light;
- and
- at least one processor and memory storing executable instructions which, when executed by the at least one processor, cause the system to:
- output, by the one or more light sources, a first flash of light at a selected wavelength and a selected intensity to the individual;
- receive, from the spectrometer, a measured wavelength and a measured intensity of the first flash of light;
- record retinal signal data corresponding to the first flash of light, wherein the retinal signal data comprises a measured impedance of a circuit that collects the electrical signals produced by the retina of the individual in response to the flashes of light;
- determine that the measured impedance of the circuit has surpassed a threshold impedance;
- after determining that the measured impedance of the circuit has surpassed the threshold impedance, output, by the one or more light sources, a second flash of light to the individual;
- and
- receive retinal signal data of the individual responsive to the second flash of light.

- determine that a rate of change of the measured impedance of the circuit has surpassed a threshold rate of change of impedance of the circuit;
- after determining that the rate of change of the measured impedance of the circuit has surpassed the threshold rate of change of impedance, output, by the one or more light sources, a second flash of light to the individual;
- and
- receive retinal signal data of the individual responsive to the second flash of light.
