From an article written by AZoNano:

 

 

Anti-reflective coating is applied to most lenses, eyeglass lenses, lasers, and objectives, however this coating only functions optimally within a narrow wavelength range.

A research team at the Max Planck Institute for Intelligent Systems in Stuttgart has developed an alternative technology by manipulating the surface instead of coating it. In comparison to conventional processes, this offers the preferred anti-reflective effect across a broader wavelength range.

In addition to this it enhances the light transmittance through surfaces. It is possible that the nanostructured surfaces may optimize touchscreens, high-energy lasers, and the output of solar modules in the future.

The team borrowed ideas from the design book for moth cornea.
