1. An apparatus for determining a characteristic of blood, compromising:

  • an imaging detector positioned to receive a first type of reflected radiation from an eye;

    a radiation directing device capable of directing a second type of radiation onto a blood vessel of the eye;

    a radiation detection assembly positioned to receive reflected radiation of the second type from the blood vessel; and

    electronics, coupled to the imaging detector, radiation directing device and radiation detection assembly, capable ofidentifying the blood vessel of the eye using reflected radiation data from the imaging detector,adjusting the radiation directing device to direct the second type of radiation onto the identified blood vessel, anddetermining a characteristic of the blood using reflected radiation data from the radiation detection assembly;

    wherein the characteristic includes blood glucose levels.
