These goggles look a bit like aviator/welding goggle designs but are not for any sort of eye-protection! They are costume goggles only! You can wear them on top of your head or on your eyes but do not use for welding or flying or motorcycling, etc.
The goggles are fully plastic and have screw-off lens-holders. Each goggle comes with two lenses per eye: one clear glass and one 50% tint plastic. The dark tint lens makes it so you can stuff electronics into the goggles without people being able to see them, but still lets thru plenty of light from your LEDs. Of course, they fit our NeoPixel 16 rings quite well (that’s what we got ’em for!)
There’s no foam or padding, you can add your own foam if you need more comfort, but basically these were meant for wearing on top of your head. Since they’re plastic, you can easily cut holes in the side parts for attaching more LEDs, control buttons, etc.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
