It’s not often that a technology provides so much instant enjoyment, astonishment, shaking, even tears. Tim Blair found a movie of a colorblind man seeing color for the first time. And there are lots of videos out there.
See one man reduced to tears. Watch this young boy react. (The next man seems very happy but says “your world is so much better than mine.”)
Know someone colorblind? Great Christmas Present (costs $350 USD plus).
(OK, so the first guy does “go on a bit” watch then skip forward…)
Technology Review explains Enchroma Glasses:
Most people have three types of color-sensing cones in their eyes: red, green, and blue. The wavelengths of light that these three cones absorb have overlapping regions. Color-blindness is often a result of a malfunctioning cone that causes wavelengths to overlap even more, resulting in poor color discrimination. The EnChroma glasses use a filter to cut out these overlapping wavelengths, allowing for a clearer distinction between colors, especially red and green.
The invention was derived from the work of Don McPherson, who earned his PhD in glass science at Alfred University. McPherson was trying to design protective eye wear for doctors […]
