Patent attributes
An illumination system adapted for an eyewear that includes a light source configured to emit a first light including a power spectrum having full width at half maximum of less than 100 nm in a first range of wavelengths and a second light including a power spectrum having full width at half maximum of less than 100 nm in a second range of wavelengths, the power spectrum of the first light and the power spectrum of the second light differ from each other, and the light source is further configured to emit pulses of light with a pre-determined time function. The pre-determined time function comprises a plurality of packets, each packet of the plurality of packets being followed by a packet interval, and each packet including a pulse alternation between a pulse of the first light and a pulse of the second light.
