A method for diagnosing a disease, disease state, or disease stage of a user is described herein. Goggles are providing having a radiation source, a radiation sensor, and a microcontroller. The goggle are assembled about a user's head. Optical data is collected from the user's eye, where the optical data includes at least two of the following: a) a wavefront of reflected radiation from the user's eye； b) a spectrum of reflected radiation from the user' eye； and c) one or more wavelengths of reflected to radiation from the user's eye. A statistical match between the user's optical data and a historical user's optical data is determined. A diagnoses of a disease, disease state, or disease stage of the user is determined based on a diagnosed disease, disease state, or disease stage of the historical user.
