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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
