Saidman, Jean 15 May 1933 A continuous 1064 nm laser source appeared red, but a 1060 nm pulsed laser source appeared green, which suggests the presence of second harmonic generation in the retina
[The visibility of the ultraviolet to the wave length of 3130] This is called the visible part of the spectrum

It was found that the eye could respond to radiation at wavelengths at least as far as 1064 nm Ohannesian, Lena; Streeter, Anthony 9 November 2001

The human eye has the ability to respond to all the wavelengths of light from 400-700 nm.
