One of the things about lenses is that you don't want them to reflect a lot of light, you want them to drink in light and to hold the light.

A moth has the same issue as a night flying creature.

It needs to drink inasmuch moonlight as it can, but it doesn't want to have that light shine back because if it does, it creates I shine which a predator can see.

So it wants its I to be absolutely black and the way it does this is it has these tiny pillars on the outside of the eye and light comes in, bounces around but it can't bounce back out.

These have been mimicked on films that are being put on cameras to make them anti reflective.

They're being put on solar cells.

So the solar cell drinks in the maximum amount of light without reflecting a whole lot, all based on a small common but actually pretty cool creature of them.
