We know that not everyone's vision is perfect, which is why some of us need glasses. But some people can also just see more stuff than others! From seeing UV and infrared light, to even having bonus color receptors in our eyes, there are a few ways that some people get more to look at than the rest of us.

Corrections:
04:55 The color corresponded with a wavelength that was about double the wavelength of the laser, not frequency.
05:04 The beam had a wavelength of 1000nm that the people saw as a light with a wavelength of near 500nm, not wave frequency.
