Adaptive photoscreening system

Briefly described, one embodiment of the system, among others, includes a device, for example a lens or lens system, positioned in the system to be between the eye of the examinee and the image detection system during photoscreening for shifting the neutralization of the system to a desired region for a specific population of examinees. The system can further include a computer control system and an environmental light source that is controlled by the computer control system such that an amount of light provided by the environmental light source is adjusted by the computer control so that ocular parameters of an examinee are within a targeted range.; Further, the system can include an irradiation system that provides multiple angle and axial eccentricity illuminations and selective wavelength irradiation based upon instructions received from the computer control system, wherein the computer control system instructs the irradiation system to provide different irradiation characteristics for different screening
