How do moth eyes help screens and solar panels?

Video · 1:45 · Crafty Clover explains, from A Million Whys Book 26

A moth's eye is covered with a pattern of tiny bumps that reduces shine, so light goes in rather than bouncing off. This helps the moth hide from predators at night. Engineers copy this by putting very tiny bumps on glass and plastic. This makes anti-glare screens and helps solar panels absorb more sunlight.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do moth eyes help screens and solar panels?

The Big Idea

Moths fly at night and need to hide. Their eyes have a special trick! It helps screens and solar panels.

Tiny Bumps

Step one: Tiny Bumps. A moth's eye is covered with a pattern of tiny bumps that reduces shine. Light goes in rather than bouncing off.

Hiding

Step two: Hiding. This helps the moth hide from predators at night. Shiny eyes would give it away.

Copying

Step three: Copying. Engineers put very tiny bumps on glass and plastic. This makes anti-glare screens and helps solar panels absorb more sunlight.

A Closer Look

Let's take a closer look! Bumps cover the eye. Light goes in. No shine escapes. Panels copy it.

Quick Facts

Quick facts! The bumps are smaller than the wavelength of light. Screens with less glare. Panels catch more sun. Hiding from owls.

Think Like a Scientist

Now, think like a scientist! With a grown-up, look at a phone screen in sunlight. Look at one with a matte screen protector if you can. Which has less glare? Which is easier to see? Why might that matter?

Outro

Moth eyes have tiny bumps that reduce shine, so light goes in instead of bouncing off. Engineers copy this to make anti-glare screens and better solar panels. Nature solved glare long before we did. Science is amazing! What will you discover next? Every question is a new adventure, so keep wondering and keep exploring with me!
