The resolution limit is one of the most important measures used in evaluating the human vision quality. It is measured typically by presenting a test object in the form of periodic fringes of different spacing to the observer subjected to the test and determining the highest spatial frequency still correctly resolved. In this paper we describe the results of such experiments for different colours of illuminating light. Our measurements suggest that the resolution in blue light is substantially worse than in white light. Using laser light it is easy to generate the sinusoidal pattern of high contrast. The resolution measurement with such object is almost 20% worse than in incoherent light of the same colour.
