For those who are color blind, a show currently airing on public TV stations marks a historic turning point – it’s the first television program ever color-corrected for them.
Fittingly, the trailblazing show is Sight: The Story of Vision, a one-hour documentary narrated by Sir Elton John about the science, medicine and technology of human vision. You’ll need to check local over-the-air listings for exact day/time/channel in your area.
The producers liken their process, dubbed “CA” for “Color Blind Accessible Correction,” to the long-established “CC” (“Closed Captioning”) for the hearing-impaired and “VD” ( “Video Description”) for low-vision and blind viewers. Specifically, CA corrects the picture for viewers with limited red-green color sensitivity – resulting in an improved viewing experience for up to 80% of them, depending on type and severity of their color blindness.
CA is based on technology used in EnChroma eyeglasses for the color blind.
The documentary itself, filmed in 4K, looks at efforts to improve and restore human vision around the world – including segments shot in Australia, Vietnam, China, Honduras, South Africa, India, Peru, Dominican Republic, Brazil, North America, and Europe. Here’s a preview:
