Anti-Reflective Moth Eyes


Moths have compound eyes that are covered by 200nm hexagonal bumps (facets) that are each spaced 300nm apart from each other (this is known as the “moth-eye structure”). Light that enters their eyes is refracted multiple times, efficiently moving light to the back of the eyes rather than reflecting it outward. Because the moth-eye structure does not reflect light from the moon, moths are able to camouflage themselves and blend into their surroundings, protecting them from predators. Having anti-reflective eyes is also helpful because moths use light to gauge their position. Since little light is lost to reflection, moths are able to utilize moonlight even though it is one million times dimmer than sunlight.

Proposals of Applied Technology

The anti-reflective moth-eye structure can be used to design glare-free television and computer screens. It can also be used to improve antireflective films for solar cells, and to develop anti-reflective black solar cells.
