The Dallas Museum offers visitors Color Vision Deficiency lenses which can help many to see a wider spectrum of colors.
The technology, which alleviates red-green CVD for about four out of five users with the disease, was developed by EnChroma, an independent company based in Berkeley, Calif. Usually genetic, red-green CVD is caused by an overlap of red and green color receptor cones in the eye, making the hues virtually indistinguishable. Lenses now provided by DMA increase the contrast between red and green color signals for users with cone overlap, allowing them to see the world with a more enriched color field.
Stop the breadboard and soldering – start crafting right away! Adafruit’s Circuit Playground is packed with LEDs, sensors, buttons, alligator clips, and more. Build projects with Circuit Playground in minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class at code.org, jump into CircuitPython to learn Python and hardware together, TinyGO , or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode and Arduino. It has a powerful processor, 10 NeoPixels, a mini speaker, infrared reception and transmission, two buttons, a switch, 14 crocodile clips and numerous sensors: touch capacitive, IR proximity, temperature, light, motion and sound. A whole world of electronics and coding awaits you, and it fits in the palm of your hand.
