That video made my screen really blurry.

What an amazing invention, AND experience, for those who suffer from color blindness.

Thanks so much for posting.

LIVING IN COLOR

EnChroma color blindness glasses can have a profound impact

on how people see their world. See for yourself.

Too bad they didn't give a hint on what technology they used for this. Did they just saturate the reds and greens on video? That would help the anomalous trichromats but not true dichromats or monochromats. Did they put glass with a notch filter in the wavelengths between the L and M cones?

If either the M or L cones are missing you'll be very red-green color blind. If one or the other is weak or if they are shifted to be closer to each other then you'll be moderately color blind. You'll be able to see bright colors like fall leaves but miss out on subtler variations.
