Abstract
This article introduces an experiment designed to investigate which wavelength of light is best reflected by the cornea. Results indicate that the human cornea reflects near-infrared or violet light more efficiently than it does bright visible light. Further, results indicate that at a wavelength of 580nm, the reflectivity of the cornea decreases to a minimum value of 37% given light incident on the cornea at an angle of 45°. A light source suitable for the detection of glaucoma has been selected based on these results, also taking into account the spectral response of a suitable photo-detector.
