## Description

The eyes have it! Add this little lens to make a big expression with Adafruit's Spooky Eyes demo for microcontrollers or Raspberry Pi. These are gorgeous glass (*not plastic/acrylic!*) lenses, with brilliant clarity and a nice convexity (is that a word?) They've even got a lip-edge so you can mount them easily with a 38mm cutout.

Adafruit have attached these to Adafruit's [Raspberry Pi Animated Eyes Bonnet](https://core-electronics.com.au/adafruit-animated-eyes-bonnet-for-raspberry-pi-pack-pi-not-included.html) Kit for a real nice upgrade!

**This product is just a single glass lens**. Perfect for use with Adafruit's [Raspberry Pi Snake Eyes Bonnet](https://learn.adafruit.com/animated-snake-eyes-bonnet-for-raspberry-pi?view=all) guide or Adafruit's [Electronic Animated Eyes](https://learn.adafruit.com/animated-electronic-eyes-using-teensy-3-1?view=all) guide. Check out both of those for the full listing of what you'll need. Of course, these work great for other purposes when you need a convex lens.

Note: These are solid glass domes, with no internal void.
