Biology

Have you ever noticed that you cannot see moths’ eyes reflecting back? Moths see well at night, but their eyes have a special built-in anti-glare feature so that light is not reflected to alert predators of their location. Scientists were intrigued by this special anti-glare feature and wanted to copy the moth’s eye so that our TVs, cell phones and other products could have glare-free displays. What they found was an orderly array of tiny bumps on the surface of the moth’s eye. These tiny bumps are so small that the wavelengths of visible light are deflected and absorbed instead of being reflected back. This is very similar to how a sound-proof room is made, except, on a larger scale; ridge-shaped foam lines the room, so the incoming sound waves are deflected into the walls and absorbed. When the moth-eye nanostructure technology was applied to solar cells, the glare was reduced from 35-40 % to only 2%.

When we have a glaring problem, like the reflection of light on solar cells, look to see how God has solved the problem. These scientists simply copied what had already been made, that is, they recognized a good design when they saw it. In the future, your anti-glare cell phone may have moth eyes!

O Lord, thou art my God; I will exalt thee, I will praise thy name; for thou hast done wonderful things; thy counsels of old are faithfulness and truth.

~ Isaiah 25:1
