Generally the emission of these dyes is considered to be beyond the range of the human eye, but there are papers which describe direct observation of the shorter emission wavelengths, e.g. J Histochem Cytochem. 2000 Mar 48(3):437-44

Subject: Far-red filter set

Hi,

we're considering buying a Y5 filter cube from Leica to see the far-red Alexas, DRAQ5 etc. but then someone mentioned to me that many (most?) people are unable to see far-red light. Does anyone know if this is true, or have experience with this (or a similar) filter cube? It has a BP 700/75 suppression filter.
