What Are Diffraction Glasses? Diffraction Glasses are created by allowing light to strike a grating (in our eyewear this is the lens) which is marked with thousands of parallel lines, the light waves are caused to spread in such a way that they produce a spectrum, or rainbow, as pictured in the video above!

Diffraction Gratings A diffraction grating is used to spatially separate light of different wavelengths. A typical diffraction grating consists of an optical material substrate, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum.
