A laser driver subsystem includes a pump diode driver, operable to generate light pulses to energize a laser, and a lithium polymer battery. The coupler is placed on the substrate, wherein the coupler is vertically aligned to the OE device. Program logic is responsive to data from the data base, where the program logic is programmed to adapt the user environment to correspond to abilities measured through the baseline tests. A next step detects an optical property of a second region of the two or more regions in the system, the second region located in a container having a reservoir for one or more modifiers of one or more optical properties of the second region.
