eye reflection spectroscopy – part 1

this experiment did only yield limited success.

the 3 most disgusting parts are labeled. the results are not accurate at all. when comparing “eyes” to “white”, it’s apparent how the “eyes” contain less of the lower / red wavelengths.

“eyes” intensity seems to peak almost all the way from green to cyan to blue. as opposed to my expectation of a single wavelength (cyan) peaking higher than all other wavelengths.
