Vobec nie.
Neviem, ake mate zdroje, ale ten "nezmysel, co sa uci na skole" sa dost 
casto opakuje v roznych variantach v roznych zdrojoch, takze si myslim, 
ze nieco na tom bude :-)

Na tom site kam som daval odkaz je napr.

Photometry is the measurement and specification of light relating to its 
effect on vision. The eye can be regarded as a radiant energy detector 
with a selective spectral response. In a well lit environment it is 
maximally sensitive to light of about 555 nm (yellow-green light) and 
relatively insensitive to far red and blue light. The function 
describing the response of the human eye to different wavelengths is 
known as the relative luminous efficiency function.
