Question

The diffraction limit, the smallest angle in degrees that can be resolved, is 250,000 arcsec × (wavelength/diameter of telescope). Humans have two eyes separated by about 8.5 cm and a marvelous computer between their ears. If this optical interferometer is just as good as one eyeball with a diameter as large as the separation of two regular eyeballs, what is the diffraction limit in arcsec of human vision for visible light at 599 nm?
