[Productivity of modelled work of near-sighted microscope operators under variable lighting]

A total of 10 examinees with shortsight at 1.0-3.5 diopters were subjected to study of visual performance similar to work at microscope with regular and chromatic (590 nm) light to tested objects. Chromatic light appeared to result in reliably higher visual performance, especially by the end ot 40-minute experiment. The study used an original method modelling visual work and a formula to calculate performance of work at microscope.
